93. Saturation and geometrical scaling in large and small systems

Michal Praszalowicz (Jagiellonian University)

07/03/2016, 16:30

I this talk we shall discuss different pieces of experimental evidence of geometrical scaling in hadronic collisions. We shall also speculate on possible fluctuations of the saturation scale and their impact on rapidity spectra.

52. Soft Pomeron in Holographic QCD

Miguel Costa

07/03/2016, 17:00

We study the graviton Regge trajectory in Holographic QCD as a model for high energy scattering processes dominated by soft pomeron exchange. This is done by considering spin J fields from the closed string sector that are dual to glueball states of even spin and parity. In particular, we construct a model that governs the analytic continuation of the spin J field equation to the region of...

55. Hadron Resonance Gas Model, Thermodynamics of QCD and Heavy Quark Physics

Dr Eugenio Megias (Max Planck Institut fur Physik, Munich)

07/03/2016, 17:30

We show how quark and glueball properties can be determined from the Hadron Resonance Gas model below the de-confinement phase transition [1,2,3,4]. This makes use of Quark-Hadron duality necessitating a tower of excited states and poses the interesting problem of identification of degrees of freedom at increasing temperatures [5]. In particular, we compute the equation of state of...

70. Description of EM structure of nonet of pseudoscalar mesons by $Unitary \& Analytic$ model leads to more accurate muon g-2 anomaly and QED $\alpha(H_Z^2)$ evaluation

Prof. Anna Zuzana Dubnickova (Comenius University)

07/03/2016, 18:30

It is demonstrated, if data on the EM form factors of the nonet of pseudoscalar mesons $\pi^+$, $\pi^0$, $\pi^-$, $K^+$, $K^0$, $\bar K^0$, $K^-$, $\eta$, $\eta'$ are described by the $Unitary \& Analytic$ model, then with more precision the muon $g-2$ anomaly and QED running fine structure constant at the squared mass of the Z-boson $\alpha(M^2_Z)$ are evaluated The most important sources...

106. Light quark mass differences in the pion eta and eta' system

Brigitte Hiller (Coimbra U.)

07/03/2016, 19:00

Isospin breaking effects in the low lying spin 0 meson sector are studied within a chiral three flavor multiquark Lagrangian with explicit symmetry breaking interactions taken to NLO in the large Nc counting.

92. Pion form factor in DSBSEs formalism

Vladimir Sauli (Nuclear Institute Rez near Prague)

07/03/2016, 19:30

New methods for solution of inhomogeneous as well as homogeneous Bethe-Salpeter equation for mesons will be discussed. Within covariant formalism of Dyson-Schwinger and Bethe-Salpeter equations, the calculation of production pion form factor will be presented and compared with recent BABAR experiment.
