H-Dibaryon Results from KTeV
Results from the KTeV experiment at Fermilab using Ξ hyperons are presented, especially the first form-factor (FF) measurement from its semi-leptonic decay. This decay, which is an important test of the Standard Model, was observed for the first time using the 1997 KTeV experiment. We also report on the analysis of a large samples of Ξ weak radiative decays, and a search for the decay of a ligh...
متن کاملHypernucleus formation and strangeness production in proton - nucleus reactions ∗
We study the production of Λ hyperons in p + A reactions on the basis of a BUU transport approach from 1.1 to 1.9 GeV and evaluate the properties of the hypernuclei produced in particular with respect to their momentum distribution in the laboratory frame. Due to elastic ΛN scattering large cross sections for the production of heavy hypernuclei in the order of 100 400 μb are predicted for p + U...
متن کاملMass of the H dibaryon.
Recent lattice QCD calculations have reported evidence for the existence of a bound state with strangeness -2 and baryon number 2 at quark masses somewhat higher than the physical values. By developing a description of the dependence of this binding energy on the up, down and strange quark masses that allows a controlled chiral extrapolation, we explore the hypothesis that this state is to be i...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
SU(3) breaking and the H dibaryon.
SU(3) breaking in quark masses affects hyperfine energy and configuration mixing in the proposed 0 dibaryon (a AA bound state). The hyperfine energy is modified substantially, so that it is much less advantageous than ln the SU(3) limit (by about a factor of 3) to recouple the spins of the quarks in two A's to form an H. Nonetheless, the 8 remains an almost pure configuration of the 490-dimensi...
