Polarization of Lambda^0 hyperons as a signature for the Quark-Gluon Plasma
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +5
The momentum distribution of Lambda^0 hyperons produced from the quark-gluon plasma (QGP) in ultra-relativistic heavy-ion collisions is calculated in dependence on their polarizati…
Energy level displacement of the excited nl state of pionic hydrogen
A. N. Ivanov, M. Faber, A. Hirtl +2
The energy level displacements of the excited nl states of pionic hydrogen and the contribution of the ns -> 1s transitions and the (pi^-p)_Coul -> 1s transitions of the pi^-p pair…
On kaonic hydrogen. Quantum field theoretic and relativistic covariant approach
A. N. Ivanov, M. Cargnelli, M. Faber +3
We study kaonic hydrogen, the bound K^-p state A_(Kp). Within a quantum field theoretic and relativistic covariant approach we derive the energy level displacement of the ground st…
On the vacua in the massless Thirring model
M. Faber, A. N. Ivanov
We calculate the most general effective potential for the massless Thirring model in dependence of the local fields of all fermion-antifermion collective excitations. We analyse th…
Dynamical breaking of conformal symmetry in the massless Thirring model
M. Faber, A. N. Ivanov
We discuss conformal invariance of the massless Thirring model. We show that conformal symmetry of the massless Thirring model is dynamically broken due to the constant of motion c…
Goldstone bosons in the massless Thirring model. Witten's criterion
M. Faber, A. N. Ivanov
We discuss the Ward identity and the low-energy theorem for the divergence of the axial-vector current in the massless Thirring model with fermion fields quantized in the chirally…
