QCD Pomerons at Non-Zero Temperature
Abstract
We consider the QCD scattering amplitudes at high energies sqrts and fixed momentum transfers sqrt-t in the leading logarithmic approximation at a non-zero temperature T in the t-channel. It is shown that the BFKL Hamiltonian has the property of holomorphic separability. The holomorphic Hamiltonian for n-reggeized gluons at temperature T is shown to be obtained from the T=0 Hamiltonian by an unitary transformation. The connection with field quantization in accelerated frames and black hole backgrounds is discussed. The effect of the running of alphaQCD on the pomeron eigenvalues is investigated.
