“…There are only slightly more than half of the number of data points compared to the T=1 case and the reliability of the data is less, given that it must be extracted from deuteron data with corrections. Again most of the data can be obtained from compilations [30,31,32] but we try to give references to original papers [28,45,46,53,61,62,63,64,65,66,67,68,69,70,71,72]. Normally the neutron result is obtained assuming that the interactions of the kaon with the proton and neutron are independent.…”

We have performed a partial-wave analysis of K + -nucleon scattering in the momentum range from 0 to 1.5 GeV/c addressing the uncertainties of the results and comparing them with several previous analyses. It is found that the treatment of the reaction threshold behavior is particularly important. We find a T=0 scattering length which is not consistent with zero, as has been claimed by other analyses. The T=0 phase shifts for ℓ > 0 are consistent with a pure spin-orbit potential. Some indications for the production of a T=0 pentaquark with spin-parity D5/2+ are discussed.

K d part1al cross sections and calculate most of the others using relations derived from isospin conservation and data from other experiments.The most striking feature of the cross section data is the abrupt rise of the total single-pion-production cross section near 1000 MBV/c.We extract isospin-O KN partial cross sections and find a rapid increase of cro(KNrr) at the threshold for the quasi-two-body reactionAs in the case of the isospin-l K+N system,it appears that the structure around 1200 MeV/c in the I total cross section for the isospin-O K+N system is well reconstructed by the sum of three smoothly varying channel cross sectionscr (KN), cr (KNrc), and cr (KNrcrc). We study the reaction KN ~ K*N 0 0 0 near threshold and find that the production and decay angular distributions can be interpreted in terms of t-channel phenomena, specifically a superposition of ru, p, and rc exchange. As is true of the lsospin-l K6 and K*N * final states, the lsospln-O K N state has a behavior near threshold which is not very different from its behavior at much higher energy.

“…A light sterile neutrino (ν s ) is necessary to explain the solar [1], atmospheric [2] and LSND [3] neutrino anomalies simulteniously via neutrino mixing schemes. The sterile neutrino has to be approximately degenerate in mass with either ν e or ν µ and it must have a mixing angle compatible with those found by the oscillation experiments.…”

A see-saw model of sterile neutrino

If the smallness of the mass of the sterile neutrino is to be explained by the seesaw mechanism, the off-diagonal entries of the mass matrix needs to be protected by some symmetry not far above the electroweak scale. We implement see-saw mechanism in a gauge model based on SU (2) q L × SU (2) l L × U (1) q Y × U (1) l Y ununified gauge group which breaks to SU (2) L × U (1) Y at the TeV region via a two-step symmetry breaking chain. The right handed diagonal block is tied to the highest scale up to which the un-unification symmetry holds. The sterile neutrino emerges from a quark-lepton mixed representation of the un-unified group.
