Strong isospin violation and chiral logarithms in the baryon spectrum
David A. Brantley, Balint Joo, Ekaterina V. Mastropas +4
We present a precise lattice QCD calculation of the contribution to the neutron-proton mass splitting arising from strong isospin breaking, MeV. We als…
Decay constants of the pion and its excitations on the lattice
Ekaterina V. Mastropas, David G. Richards
We present a calculation using lattice QCD of the ratios of decay constants of the excited states of the pion, to that of the pion ground state, at three values of the pion mass be…
Lattice study of the leptonic decay constant of the pion and its excitations
Ekaterina V. Mastropas, David G. Richards
We present a calculation of the decay constant of the pion, and its lowest-lying three excitations, at three values of the pion mass between around 400 and 700 MeV, using anisotrop…
A hadron model with breaking of spatial homogeneity of vacuum
E. N. Myasnikov, E. V. Mastropas
A possible breaking of spatial homogeneity of vacuum due to the interaction between quark and Bose-field is analyzed. It is shown that in this case quark can be in a localized stat…
