Long distance effects and strangeness in the nucleon
To calculate the magnetic protons momentum space separation separation
2014/12/20
We discuss the calculation of the strange magnetic radius of the proton in chiral perturbation theory. In particular, we investigate the low-energy component of the loop integrals involving kaons. We ...

Improved method for calculating nucleon strangeness
2011/1/7
The strange quark content of the nucleon, as well as other matrix elements, can be calculated on the lattice by examining correlations between the nucleon propagator and the quark condensate. The larg...
The implications of chiral symmetry breaking and SU(3) symmetry breaking have been studied in the chiral constituent quark model ( CQM). The role of hidden strangeness component has been investigated ...
