Abstract
We consider the QCD scattering amplitudes at high energies s and fixed momentum transfers − 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.
