For the baryon sector at low densities we employ the Walecka model. Applying Gibbs criteria to this composite system...

Including all three Ioffe currents we get from one wave function both the negative neutron charge radius 〈 r 2〉 neutron=-0.108 fm 2 and the decreasing d/u ratio in the proton for x Bj increasing from 0.5 to 1. 展开 DOI: 10.1016/0370-2693(85)91382-6 被引量: 6 ...

Using QCD sum rules, we calculate the electric dipole moment of the neutron d_n induced by all CP violating operators up to dimension five. We find that the chromoelectric dipole moments of quarks ilde d_i, including that of the strange quark, provide significant contributions comparable in ...
we can only guess what they are. We have named themquarks. We believe that two types of quarks — one named “up” and the other “down” — make up the proton and the neutron. Quarks are held together by a force dubbed the chromo force, represented by particles namedgluons, which ar...
any up-type quark (up, charm, and top quarks) can change into any down-type quark (down, strange, and bottom quarks) and vice versa.This flavor transformation mechanism causes the radioactiveprocess of beta decay,in which a neutron "splits" into a proton,an electron and an electron antin...
A quark-antiquark pair forms a meson. There are six species of quarks and, correspondingly, six species of antiquarks. Quarks appear so far to be permanently confined to the proton or neutron. Any attempt to liberate them results in the copious production of mesons, that is, quark-anti...
