[Theory-seminars] seminar next week

[Vincent Mathieu]

Hi all,

there is no seminar on Monday Oct 8 (Columbus Day in the US except JLab). 
On Wednesday Oct 10 1pm, there will be a cake seminar by José Goity. 

Title: BChPT x 1/Nc: a consistent approach to baryon chiral dynamics

Abstract: BChPT has been notoriously problematic in describing basic 
properties of baryons, especially in SU(3). The problems are related to 
large NLO and NNLO corrections. Those problems were identified to be the 
result of the failure of implement consistency with the 1/Nc expansion 
of QCD into the EFT. It will be shown that by implementing that 
consistency the chiral expansion shows dramatically improved 
convergence. The mechanism that leads to such improvements will be 
explained and applied to the especially challenging case of SU(3) 
baryons. The applications will include  mass relations, sigma terms of 
the nucleon, SU(3) breaking of the vector current charges and axial 
couplings. Quark mass dependencies using results from lattice QCD will 
provide useful testing for the approach.

Cheers,
Vincent
