Rho
meson width at finite temperature
from finite energy QCD sum rules, A.
Ayala,
Universidad Nacional Autónoma de México,
Mexico − Finite energy
sum
rules at finite temperature have proven to be an efficient tool
to explore
non-perturbative properties of the QCD phase diagram. In this talk I show that
these can be applied
to study the properties of the rho meson at finite temperature.
In particular, I
show that under the
simplifying assumption of a constant rho mass with temperature
one can obtain
simultaneous solutions for the energy threshold for the onset of
the continuum,
the rho width and the rho decay constant consistent with an
increase of the rho
width with temperature.
