Recent analysis of proton and deuteron deep-inelastic scattering data have suggested that the extracted d/u quark distribution ratio at large x may be significantly larger than previously believed, if the data are corrected for nuclear binding effects in the deuteron. We examine the sensitivity to the large-x d/u ratio of lepton asymmetries from W-boson production in pp and pp collisions at lar...

An enhancement of antiprotons produced in p + d reaction in comparison with ones in p + p elementary reaction is investigated. In the neighborhood of subthresh-old energy the enhancement is caused by the difference of available energies for antiproton production. The cross section in p + d reaction, on the other hand, becomes just twice of the one in elementary p + p reaction at the incident en...

In ultraperipheral relativistic deuteron on heavy-ion collisions, a photon emitted from the heavy nucleus may dissociate the deuterium ion. We find deuterium breakup cross sections of 1.38 barns for deuterium-gold collisions at a center of mass energy of 200 GeV per nucleon, as studied at the Relativistic Heavy Ion Collider, and 2.49 barns for deuterium-lead collisions at a center of mass energ...

vVe propose the nucleon-nucleon potential of one-boson-exchange type in the triplet even (3E) state, which is determined so as to reproduce the two-nucleon scattering data below 350 MeV as well as the deuteron data. In an earlier paper by Kishi, Sawada and Watari, the hard core radius in 3E state was larger than those in other states. In this paper we take the same hard core radius in 3E state ...

As known, electron vacuum polarisation by nuclear Coulomb field produces the Uehling potential with range ℏ/2mec. Similarly, neutrino Z boson a long-range ∼GF2/r5 very large ℏ/2mνc. Measurements of macroscopic effects produced Geff2/r5 give limits on effective interaction constant Geff which exceed Fermi GF many orders magnitude, while from spectroscopy simple atomic systems are approaching Sta...

The existence of a new interaction involving the electron neutrino and nucleons, which has received convincing confirmation through good agreement between theoretical experimental results concerning all observable processes with solar neutrinos, should also inevitably manifest itself in deuteron disintegration by reactor antineutrinos neutral currents. In this paper, analytical numerical charac...
