Shear viscosity of a pion gas due to and interactions
Sabyasachi Ghosh, Gastao Krein, Saurav Sarkar
We have calculated the shear viscosity of pion medium, where propagating pion has some finite thermal width due to interaction with the low mass resonances, and . With the h…

The Gerasimov-Drell-Hearn sum rule and the single-pion photoproduction multipole E0+ close to threshold
D. Drechsel, G. Krein
The long-standing discrepancy between the Gerasimov-Drell-Hearn sum rule and the analysis of pion photoproduction multipoles is greatly diminished by use of s-wave multipoles that…

Optimized expansion for the Walecka model
G. Krein, D. P. Menezes, M. B. Pinto
The optimized -expansion is used to study vacuum polarization effects in the Walecka model. The optimized -expansion is a nonperturbative approach for field theoretic models…
