DESCRIPTION:Speakers: Mahfuzur Rahaman (Variable Energy Cyclotron Centre\,

nstitute\, Anushaktinagar\, Mumbai\, India.)\nClassical and quantum Tsalli
s distributions have been widely used in many branches of natural sciences
. But\, the quantum field theory of the Tsallis distributions is relativel
y a less explored arena. In the article **arXiv:1906.02893v2 [hep-ph]**\,
we derived the expressions for the thermal two-point functions for the Tsa
llis statistics with the help of the corresponding statistical mechanical
formulations. In the conference\, we will show that the quantum Tsallis di
stributions used in the literature appear in the thermal part of the propa
gator much in the same way the Boltzmann-Gibbs distributions appear in the
conventional thermal field theory. As an application of our findings\, th
e thermal mass in the $ \\phi^4 $ scalar field theory within the realm of
the Tsallis statistics will also be discussed. For small system like qua
rk gluon plasma (QGP) where the application of Boltzmann-Gibbsstatistics i
s uncertain\, the thermal field theoretic formulation developed in this wo
rk for Tsallis statistics will have crucial importance. The thermal spectr
al function of quarks and gluons estimated using BG and Tsallis statistics
will differ (as the case for $ \\phi^4 $ interaction) which may have si
gnificant impact on the signals of QGP.\n\nhttps://indico.cern.ch/event/79
