QCD Pomerons at Non-Zero Temperature
摘要
We consider the QCD scattering amplitudes at high energies sqrt{s} 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 alpha_{QCD} on the pomeron eigenvalues is investigated.
