“Light meson-baryon dynamics and generation of resonances”

Profa. Kanchan Khemchandani - UNIFESP

Dia: 10 de outubro, terça-feira, às 17h.

Local: Sala 335, Ala 2, Edifício Principal.

Resumo da palestra:

Meson-baryon scattering amplitudes are often calculated within a coupled channel approach with the motivation of studying a dynamical formation of resonances. Typically, a particular class of mesons and baryons are considered as coupled channel in such studies and the (kernel) amplitudes used for the resolution of scattering equations are obtained within a nonrelativistic treatment. The justification behind this latter approximation is that it is essentially the dynamics near the thresholds of different meson-baryon channels which is important in determining the possibility of the generation of resonances. In this talk, I will raise the question if we can rely on the standard nonrelativistic treatment of the amplitudes and the differences in the results obtained when treating the amplitudes both relativistically and nonrelativisically.
