Jalilian-Marian, Iancu, McLerran, Weigert, Leonidov, Kovner evolution at next to leading order
Alex Kovner, Michael Lublinsky, Yair Mulian
The Jalilian-Marian,Iancu, McLerran, Weigert, Leonidov, Kovner (JIMWLK) Hamiltonian for high energy evolution of QCD amplitudes is presented at the next-to-leading order accuracy i…
The Curious Case of an Effective Theory
Ibrahim Burak Ilhan, Alex Kovner
We describe an effective theory of a scalar field, motivated by some features expected in the low energy theory of gluodynamics in 3+1 dimensions. The theory describes two propagat…
QCD Reggeon Calculus From KLWMIJ/JIMWLK Evolution: Vertices, Reggeization and All
T. Altinoluk, C. Contreras, A. Kovner +3
We show explicitly how the high energy QCD evolution generated by the KLWMIJ Hamiltonian can be cast in the form of the QCD Reggeon Field Theory. We show how to reduce the KLWMIJ H…
Some Comments on Ghosts and Unitarity: The Pais-Uhlenbeck Oscillator Revisited
Ibrahim Burak Ilhan, Alex Kovner
We give a simple discussion of ghosts, unitarity violation, negative norm states and quantum vs classical behavior in the simplest model with four derivative action - the Pais-Uhle…
