DESCRIPTION:Speakers: Jakub Vosmera (CEICO\, Institute of Physics\, Czech
Academy of Sciences)\nStarting with a general string field theory action w
hich possesses an $A_\\infty$ (or $L_\\infty$) structure\, we derive an ef
fective action for the massless degrees of freedom. We show that the verti
ces of this effective action again exhibit an $A_\\infty$ (or $L_\\infty$)
structure. Repeating this procedure for the WZW-like heterotic and open s
uperstring field theories formulated in the large Hilbert space\, we find
that the computation of the quartic vertex of the effective action for mas
sless modes at zero momentum localizes on the boundary of the worldsheet m
oduli space. We show that our results can be used to efficiently deal with
several concrete superstring backgrounds of interest.\n\nhttps://agenda.i

DESCRIPTION:Speakers: Maurizio Muratori (University of Modena and Reggio E
milia)\nNumerical Worldline (WL) Monte Carlo (MC) techniques for particle
path integrals in flat spacetimes have been deeply developed in order to e
xtract physical information from QFT systems. It is however possible to ex
tend such procedures to the case of (Euclidean) curved spaces\, where the
proper-time discretization of a bosonic worldline point-particle is treate
d similarly to a time-slicing regularization for the associated quantum pa
th integral. In particular\, it induces a well-known counterterm in the th
eory which\, together with curvature effects arising directly from the cur
ved metric tensor\, plays the role of an additional potential. To test the
setup\, the numerical evaluation of the heat kernel of a free scalar poi
nt-particle on a 4-hyperboloid is presented\; such system was already stud
ied analytically\, and the expressions of the associated effective potenti
al and of the metric tensor were provided in closed form. The curved space
problem was turned into a flat space one\, allowing for a direct comparis
on between WLMC techniques in curved (the test) and in flat (the check) sp

DESCRIPTION:Speakers: Alice Aldi (INFN-Sezione Roma 2)\nThe famous paper [
1] by Kawai\, Lewellen and Tye (KLT) showed that $n$-closed strings scatte
ring amplitudes at tree-level on the sphere can be calculated and written
in terms of $n$-open strings scattering amplitudes on the disk\, using wel
l known techniques of complex analysis. Their results can be summarised (s
chematically) by “$Gravity = (Gauge)^2$”. In the context of Orientifol
d theories\, tree-level scattering amplitudes involving closed string Tach
yons were considered in order to extend their relationship with scattering
amplitudes of open string Tachyons. String $g_s$-perturbation theory for
orientifold theories involves both $oriented$ and $unoriented$ surfaces\,
having Euler characteristic $\\chi = 2 -2g -b-c$ with g-genus\, b-boundar
ies and c-crosscaps. Oriented theories at tree-level are analysed in [1] a
nd [2\,3]\, where only oriented surfaces enter the calculations\, respecti
vely Sphere (S2) and Disk (D2). Following [1\,2\,3]\, we investigate the l
ess studied tree-level string scattering amplitudes on an unoriented surfa
ce\, the Real Projective Plane (RP2) [4]\, and the relation between $n$-cl
osed strings and 2$n$-open strings is found.\n\nhttps://agenda.infn.it/eve

braic structures are ubiquitous in fundamental physics. For instance\, $A_

heory. Importantly\, via the Batalin-Vilkovisky formalism\, any Lagrangian
field theory admits an $L_\\infty$-algebra that governs all of its physic
s including field equations\, symmetries\, and Noether identities. In this
talk\, I will explain the connection between higher algebraic structures
and tree-level scattering amplitudes. In particular\, I will prove that po

with the possibility to extend it to (excited) twist fields\, both in the
Abelian and non Abelian cases.\n\nWe consider two-dimensional fermions in
the presence of point-like defects in the time-like direction correspondin
g to spin fields which provide non trivial boundary conditions. We solve t
hem and the equations of motion to define a basis of modes in the Euclidea
n formulation. We compute the algebra of creation and annihilation operato
rs necessary to build the Fock space in the presence of defects. With the
definition of the in-vacuum\, we then compute the contractions of the fiel
ds and the stress-energy tensor which shows that we are indeed considering
a CFT\, notwithstanding the time dependent defects. We then proceed to bu

the spin fields.\n\nhttps://agenda.infn.it/event/19816/contributions/10707

DESCRIPTION:Speakers: Carlo Heissenberg (Nordita\, Stockholm)\nAsymptotic
symmetries at null infinity do not seem to play a fundamental role in high
er dimensions: in constrast with the four-dimensional case\, in $D>4$ it i
s indeed possible and natural to describe radiative solutions to Maxwell's
and Einstein's equations without ever enlarging the asymptotic symmetry g
roup beyond the standard global symmetries. Similarly\, memory effects do
not show an immediate link with nontrivial symmetries acting asymptoticall
y\, thus pointing to their absence in higher dimensions. However\, these c
onclusions seem at odds with the connection asymptotic symmetries and memo
ry effects share with soft theorems\, whose validity extends beyond $D=4$.
\nWe investigate this issue studying memory effects associated to Abelian
and non-Abelian radiation getting to null infinity\, in arbitrary even spa
cetime dimensions. Together with classical memories\, linear and non-linea
r\, given by permanent kicks in the velocity of probe particles\, we also
discuss the higher-dimensional counterparts of quantum memory effects\, ma
nifesting themselves in modifications of the relative phases describing a
configuration of several probes. \nAdopting the Lorenz gauge\, we illustra
te how one can interpret such memory effects as the action of suitable res
idual symmetries acting near null infinity and propose a strategy for defi
ning infinite-dimensional asymptotic symmetries of Maxwell’s theory in a
ny dimension\, eiher even and odd.\n\nhttps://agenda.infn.it/event/19816/c

with arbitrary picture number. The usual cohomology problem in the Large
Hilber Space can then be reformulated in terms of a dual problem with a tw
o parameters gauge symmetry. The interactions then emerge in a way analogo
us to Berkovits' picture zero NS theory and do not exhibit an explicit $A_

DESCRIPTION:Speakers: Veronica Guidetti (Istituto Nazionale di Fisica Nucl
eare)\nIn recent years the idea of bosonic ultralight CDM (also called fu
zzy dark matter\, FDM) has been proposed\, in one of its prominent version
s it states that DM is made of ultralight axion-like particles that form h
alos as Bose-Einstein condensates. In this theory each axionic particle ca
n develop structures on de Broglie scale thanks to gravitational effects.
A prominent soliton\, i.e. a state where self-gravity is balanced by the e
ffective pressure arising from the uncertainty principle\, develops at the
center of every bound halo. The extremely high value of the decay constan
t together with the possible multiple axionic nature of FDM have been clai
med to be a possible sign in favour of the string axiverse\, where a pleni
tude of axion like particle naturally arise in 4D effective theory. I will
point out that obtaining a fuzzy dark matter axion with the correct mass
and decay constant is a big challenge for string theory\, being also its
existence in contrast with WGC .\n\nhttps://agenda.infn.it/event/19816/con

DESCRIPTION:Speakers: Alessandro Mininno (Instituto de Fisica Teorica UAM-

1]\, we apply dimer diagram techniques to uncover discrete global symmetri
es in the fields theories on D3-branes at singularities given by general o
rbifolds of general toric Calabi-Yau threefold singularities. The discrete
symmetries are discrete Heisenberg groups\, with two generators A\,B with
commutation AB=BAC\, with C a central element. These generators depend on
the abelian orbifold. This fully generalizes observations in particular o
rbifolds of the flat space\, the conifold and other toric Sasaki-Einstein
manifolds. The generator A is realized as a shift in the dimer diagram\, a
ssociated to the orbifold quantum symmetry\; the action of B is determined
by equations describing a 1-form in the dimer graph in the unit cell of t
he parent theory with twisted boundary conditions\; finally\, C is an elem
ent of the (mesonic and baryonic) non-anomalous U(1) symmetries\, determin
ed by geometric identities involving the elements of the dimer graph of th
e parent theory. These discrete global symmetries of the quiver gauge theo
ries are holographically dual to discrete gauge symmetries from torsion cy
cles in the horizon. Our findings allow to easily construct the discrete s
ymmetries for infinite classes of orbifolds.\n\n\n [1]: https://arxiv.org

a5 for mixed boundary conditions\, keeping all the weights of various geo

a $T(U(N))$ SCFT\, thus playing the role of non-conventional matter. In t
his talk I will discuss the main features of S-fold SCFTs\, focusing on th
eir moduli space and how mirror symmetry relates them. The construction of
these theories can be extended to various gauge groups\, and in particula
r I will discuss the ones involving $G_2$ gauge group. Moreover\, the issu
