Feynman Diagrams and Rooted Maps
A. Prunotto, W. M. Alberico, P. Czerski
The Rooted Maps Theory, a branch of the Theory of Homology, is shown to be a powerful tool for investigating the topological properties of Feynman diagrams, related to the single p…
Survival of Bc mesons in a hot plasma within a potential model
W. M. Alberico, S. Carignano, P. Czerski +3
We extend a previous work on the study of heavy charmonia and bottomonia in a deconfined quark-gluon plasma by considering the Bc family of mesons. With the introduction of this bo…
Screening Masses of Scalar and Pseudo-scalar Excitations in Quark-gluon Plasma
P. Czerski, W. M. Alberico
The quark-gluon plasma (QGP) excitations, corresponding to the scalar and pseudoscalar meson quantum numbers, for different temperatures are calculated. Analysis is performed in th…
Meson Correlation Function and Screening Mass in Thermal QCD
Piotr Czerski
Analytical results for the spatial dependence of the correlation functions for all meson excitations in perturbative Quantum Chromodynamics, the lowest order, are calculated. The m…
HTL approach to the viscosity of quark plasma
P. Czerski, W. M. Alberico, S. Chiacchiera +4
The quark viscosity in the quark gluon plasma is evaluated in HTL approximation. The different contributions to the viscosity arising from the various components of the quark spect…
Meson Screening Masses in the Interacting QCD Plasma
W. M. Alberico, A. Beraudo, A. Czerska +2
The meson screening mass in the pseudoscalar channel is calculated from the momentum dependent meson spectral function, using HTL fermionic propagators. A careful subtraction proce…
