70. Study of exotic f${}_0$ and f${}_1$ states with ALICE

Francesca Bellini (Istituto Nazionale di Fisica Nucleare)

Invited

Despite most of the known observed hadrons fit into the quark model picture formulated back in the 1960s', there exist several resonances whose properties suggest an exotic structure. In particular, the nature of f${}_0$(980), f${}_1$(1285), and f${}_0$(1710) states is still debated, as these have been proposed as ordinary two-quark states, compact tetraquarks, hadronic molecules, hybrid states or...

55. Resonance production in the STAR experiment

Invited

Relativistic heavy ion collisions provide a unique opportunity for investigating nuclear matter’s characteristics under extreme conditions of high temperature and density. Resonance particles, such as K∗0 and φ, are considered good tools for probing the medium generated during these collisions. Specifically,K∗0, with a relatively short lifetime of approximately 4 fm/c, undergoes decay within...

90. In-medium effects in φ meson production in heavy-ion collisions from subthreshold to relativistic energies

Elena Bratkovskaya (GSI, Darmstadt & Frankfurt Uni.)

08/11/2023, 15:20

Invited

We investigate the hidden strange $\varphi$ meson production in heavy-ion collisions from subthreshold ($E_{kin}\sim 1$ A GeV) to relativistic ($E_{kin}\sim 21$ A TeV) energies as well as its coupling to the open strange mesons (kaons, antikaons) and their productions.
Our study is based on the off-shell microscopic Parton-Hadron-String Dynamics (PHSD) transport approach which is applicable for...

84. LHCb on technical aspects how to search and find resonances, also using AI techniques.

Paolo Gandini (Istituto Nazionale di Fisica Nucleare)

08/11/2023, 15:45

Invited

I will describe how to look for resonances at the LHCb experiment at CERN. Searches usually involve small signal yields, therefore careful and advanced techniques are required to reject the huge background coming from the hadronic collisions.

45. Measurement of azimuthal anisotropy of the ${\mathrm{f}}_0(980)$ and ${\mathrm{D}}^0$ mesons in heavy ion collisions at CMS

Nihar Ranjan Saha (Indian Institute of Technology, Madras (IN))

08/11/2023, 16:10

Contributed

We present novel insights into the elusive ${\mathrm{f}}_0(980)$ hadron's quark composition and the interaction of heavy charm quarks with the quark-gluon plasma (QGP) through the anisotropic flow measurement of ${\mathrm{D}}^0$ in Heavy-Ion collisions. The ${\mathrm{f}}_0(980)$, whose precise configuration has remained controversial, is reconstructed for the first time via its dominant decay channel,...
