Description
We predict that direct photon production in pp collisions at 7~TeV
will get at least 10 times enhanced compared to the next to leading
order pQCD predictions, at low transverse momentum ($\pt$ $\lesssim$
10~GeV/c), due to the thermal photon emissions from a quark gluon plasma
(QGP) formed in high multiplicity events. Thus the enhancement of
direct photon production at low $\pt$ can be a QGP signal in pp collisions.
