The effective description of non-strange hadrons low-energy electro-weak transitions
Gevorg G. Bunatian
Starting with the general principles of global and local symmetries, the effective pion-nucleon lagrangian, essentially non-linear in pion field, to describe the non-strange hadron…
On the usage of electron beam as a tool to produce radioactive isotopes in photo-nuclear reactions
G. G. Bunatian, V. G. Nikolenko, A. B. Popov
We treat the bremsstrahlung induced by initial electron beam in converter, and the production of a desirable radio-isotope due to the photo-nuclear reaction caused by this bremsstr…
Radiative Corrections to the Neutron Beta-decay within the Standard Model
G. G. Bunatian
Starting with the basic Lagrangian of the Standard Model, the radiative corrections to the neutron beta-decay are acquired. The electroweak interactions are consistently taken into…
Inquiry for the π^+ π^- bound state conversion in two π^0 as being due to the Weinberg pion-pion-interaction lagrangian
G. G. Bunatian
In the work presented, the decay of the pionium, that is the π^+ π^- bound state, into two π^0 is studied, the ππ-interaction causing this transition being described by the underly…
Temperature Dependence of the Chiral Condensate from an Interacting Pion Gas
G. Bunatian, J. Wambach
By exploiting the fact that the chiral condensate is related to the derivative of the free-energy density with respect to the bare quark mass we calculate the temperature dependenc…
