The string-derived Bern-Kosower formalism was originally developed for the computation of on-shell gluon amplitudes. In previous work we have, using worldline methods, shown how to extend and optimize this formalism as a tool for obtaining form-factor decompositions of the off-shell 1PI gluon amplitudes. Following an earlier rederivation of the three-gluon (Ball-Chiu) form factor decomposition, h ... More

A search for the Standard Model Higgs boson decaying to tau pair has been performed in pp collision data recorded by CMS detector at LHC at centre-of-mass energy 8 TeV (7 TeV) corresponding to an integrated luminosity 20/fb (5/fb). The production modes considered are gluon-gluon fusion, VBF and associated production with a vector boson. The analysis strategy will be reported, focusing on the estim ... More

Heavy quarks (charm and beauty) are excellent probes to investigate the properties of the strongly interacting matter formed in heavy-ion collisions, where a Quark-Gluon Plasma (QGP) is produced. Due to their large mass, charm and beauty quarks are produced in hard partonic scattering processes in the initial stages of the collision, before the formation of the QGP. While traversing the medium the ... More

The ALICE detector at the LHC is specifically designed to investigate the properties of the hot and dense medium, consisting of deconfined quarks and gluons (QGP), created in highenergy heavy-ion collisions. Heavy–flavour particles are very special probes to investigate the properties of such a medium, since they are mainly produced in the initial phase and could experience the full evolution o ... More

Recently we have proposed unitary symmetry relations between the Light-Cone QCD sum rules with meson and photon distribution amplitudes (DA's). But they are not suitable if one deals with the baryon DA's because in this case interpolating currents have different nature: one of them is baryon current while the other one is either a meson or a photon current. As the resulting formules with baryon DA ... More

Observing renewed interest in (semi-) relativistic descriptions of bound states, we would like to make a few comments on the eigenvalue problem posed by the spinless Salpeter equation and, illustrated by the example of the Woods-Saxon potential, recall various elementary tools that practitioners looking for analytic albeit approximate solutions might find useful in their quest.

In the LHC era, the discovery of New Physics signals is the major ambition of the high energy physics community and flavor physics can provide access to new heavy particles (Kaluza—Klein modes, supersymmetric particles …) in complementary way with respect to direct searches. Signals of possible deviations with respect to the Standard Model (SM) have been recently claimed both by BaBar and LHC ... More

In spite of undeniable similarities of the applied techniques, rather different challenges are encountered when extracting, from QCD sum rules for two-point correlators of appropriate heavy-light interpolating currents, the decay constants of charmed mesons of, on the one hand, pseudoscalar nature and, on the other hand, vector nature. This observation justifies a careful reassessment of the corre ... More

The existence of stars with masses up to 2 M_S and the hints of the existence of stars with radii smaller than about 11 km seem to require, at the same time, a stiff and a soft hadronic equation of state at large densities. We argue that these two apparently contradicting constraints could be actually an indication of the existence of two families of compact stars: hadronic stars, whose equation ... More

We calculate the shifts in the masses and decay constants of B and D mesons in nuclear medium in the frame work of QCD sum rules. We write the shifts in the masses and decay constants in terms of B-N and D-N scattering lengths and an extra phenomenological parameter entered to calculations. Computing an approciate forward scattering correlation function, we derive the QCD sum rules for the B-N and ... More

The η transition form factor is analyzed for the first time in both space-like and time-like regions at low and intermediate energies in a model-independent approach through the use of rational approximants. With the release of the η → e+e−γ data on the very low energy region by the A2 Collaboration we extract the most precise slope and curvature parameters of the form factors as well as th ... More

Based on the mathematically well defined Pade Theory, a theoretically safe new procedure for the extraction of the pole mass and width of a resonance is proposed. In particular, thanks to the Montessus de Ballore theorem we are able to unfold the Second Riemann Sheet of an amplitude to search for the position of the resonant pole in the complex plane (arXiv:1306.6308 [hep-ph]). The method is syste ... More

In the first three years of the LHC operation, ALICE has measured identified light flavour hadrons in a wide transverse momentum range. The measurements have been performed in the three collision systems: pp at $\sqrt(s)$ = 0.9, 2.76 and 7 TeV, p-Pb at $\sqrt(s_{NN})$ = 5.02 TeV and Pb--Pb at $\sqrt(s_{NN})$ = 2.76 TeV. In this poster, the latest results on transverse momentum distributions, par ... More

A non-local Nambu-Jona-Lasinio model can be derived from QCD in the low-energy limit. In this way, it is possible to fix all the free parameters of the model with physical ones. We use this approach to derive a local limit to the Nambu-Jona-Lasinio model with the parameters those obtained from QCD in order to fix the physical parameters of $\rho$ condensation. $\rho$ condensation is a consequence ...

QCD at finite temperature has been usually studied within the standard Boltzmann-Gibbs statistics. One of the standard properties of this is that entropy is extensive, which means that for two systems A and B which are independent (in the sense that the probabilities of the states of A+B factorize into those of A and B), the entropy of the joint system S(A+B) is equal to the sum of the individual ...

Since quarks interact with each other through the exchange of colored self-interacting gluons, QCD predicts the existence of hybrid configurations, composed by a quark, an antiquark and an excited gluon. This structure gives rise to hybrid mesons, whose $J^{PC}$ quantum numbers can be either ordinary or exotic. In the former case hybrid configurations are not easily observable because they mix wit ... More
