On the estimate of the sigma^(I = 1)_(KN)(0)-term value from the energy level shift of kaonic hydrogen in the ground state
A. N. Ivanov, M. Faber, V. A. Ivanova +2
Using the experimental data on the energy level shift of kaonic hydrogen in the ground state (the DEAR Collaboration, Phys. Rev. Lett. 94, 212302 (2005)) and the theoretical value…
On the Sigma^0 --> Lambda^0 + gamma decay in the Effective quark model with chiral U(3)xU(3) symmetry
A. N. Ivanov, A. Ya. Berdnikov, Ya. A. Berdnikov +5
We analyse the angular distributions of the Sigma^0 --> Lambda^0 + gamma decay rate in the laboratory and in the rest frame of the Sigma^0 - hyperon in the dependence on baryon pol…
On strangeness production in the reactions pp -> p Lambda^0 K^+ and pn -> n Lambda^0 K^+ near threshold
A. N. Ivanov, Ya. A. Berdnikov, M. Faber +3
The cross sections for the reactions pp -> p Lambda^0K^+ and pn -> n Lambda^0K^+ are calculated near threshold of the final states. The theoretical ratio of the cross sections R =…
Lattice QCD at finite density via a new canonical approach
Andrei Alexandru, Manfried Faber, Ivan Horváth +1
We carry out a finite density calculation based on a canonical approach which is designed to address the overlap problem. Two degenerate flavor simulations are performed using Wils…
On the renormalization of the sine-Gordon model
H. Bozkaya, M. Faber, A. N. Ivanov +1
We analyse the renormalizability of the sine-Gordon model by the example of the two-point Green function up to second order in alpha_r(M), the dimensional coupling constant defined…
Recent Theoretical Studies on Hadronic Atoms
A. N. Ivanov, M. Cargnelli, M. Faber +5
A report contains a review of recent theoretical investigations on kaonic atoms carried out at Stefan Meyer Institute of the Austrian Academy of Sciences. We discuss (1) a phenomen…
On isospin-breaking corrections to the energy level displacement of the ground state of kaonic hydrogen
A. N. Ivanov, M. Cargnelli, M. Faber +5
In the model of low-energy bar-K N interactions near threshold (EPJA 21, 11 (2004); 25, 79 (2005)) we calculate isospin-breaking corrections to the energy level displacement of the…
