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…
Phenomenological model of the Kaonic Nuclear Cluster K^-pp in the ground state
A. N. Ivanov, P. Kienle, J. Marton +1
A phenomenological model is proposed for the analysis of the properties of the Kaonic Nuclear Cluster (KNC) Kpp in its ground state. Inside the KNC K^-pp we describe the relative m…
On renormalizability of the massless Thirring model
H. Bozkaya, A. N. Ivanov, M. Pitschmann
We discuss the renormalizability of the massless Thirring model in terms of the causal fermion Green functions and correlation functions of left-right fermion densities. We obtain…
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 =…
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…
