Relativistic QPC model for reduced V → Pγ, P → γγ, etc. decays and enhanced E.M. tadpoles
No full textCertain relativization prescriptions for the quark pair creation (QPC) model are found to lead to an understanding of the connected problems of the reduced radiative decays and enhanced e.m. mass differences within a unified framework. In particular, we find excellent agreement with most V → Pγ, P → Vγ and P → γγ as well as η → 3π, η → π0γγ decays, all without free parameters
Transverse electromagnetic waves with finite energy, action, and ∫E →B →d<SUP>4</SUP>x
No full textTransverse electromagnetic waves possessing finite energy, action, and ∫E →B →d4x are obtained in 3 + 1 dimensions as a solution of the source-free Maxwell's equation in vacuum
Observation of γγ → φρ<sup>0</sup> and γγ → φρ
No full textTwo-photon production of the hadronic final states K<sup>+</sup>K<sup>−</sup>π<sup>+</sup>π<sup>−</sup> and K<sup>+</sup>K<sup>−</sup>π<sup>+</sup>π<sup>0</sup>π<sup>−</sup> has been studied using the ARGUS detector at the e<sup>+</sup>e<sup>−</sup> storage ring DORIS II at DESY. The cross sections of the reactions γγ → φρ<sup>0</sup> and γγ → φρ have been measured for the first time. In addition, angular distrubutions have been determined for the reaction γγ → φρ<sup>0</sup> → K<sup>+</sup>K<sup>−</sup>π<sup>+</sup>π<sup>−</sup>
Hb Southampton [B106(G8)Leu→PRO, CTG→CCG] in a Uruguayan woman
No full textHemoglobin Southampton (also known as hemoglobin Casper) is a rare hemoglobin structural variant resulting from a substitution of a leucine residue for proline at codon beta106 [beta106(G8)Leu→Pro, CTG→CCG]. It is very unstable and associated with severe hemolytic anemia. We detected this mutation in a 37-year-old Uruguayan woman with a history of severe chronic hemolytic anemia since her childhood. According to our knowledge this is the first time that this variant has been found in the Uruguayan population

Study of the decays K→μνe<SUP>+</SUP>e<SUP>-</SUP> and K→eνμ<SUP>+</SUP>μ<SUP>-</SUP>
No full textThe decays K→μνe+e- and K→eνμ+μ- have been discussed in a hard-meson model. The structure-dependent effects can be seen in the K→μνe+e- mode only at large values of the mass of the virtual photon. However, in K→eνμ+μ- decay the structure-dependent terms predominate, even though the branching ratio is small
Unified treatment of the pd→dp and pp→π<SUP>+</SUP>d processes in a model of N and N<SUP>*</SUP> exchanges
No full textWe present a unified account of two related processes, pd→dp and pp→π+d, in a scheme of higher baryon couplings developed by this group. The work which represents a considerably improved version of an earlier model for the study of the pd→dp process at moderately high energies (1.0-1.5 GeV) is now extended to include (i) lower energies (down to 300 MeV) for pd→dp, and (ii) the related process pp→π+d, within a common set of assumptions for the N and N* exchange vertices. The fits to the data for both the processes come out rather well over their respective energy ranges, which are appreciable
Measurement of the branching fraction scrB(τ<sup>-</sup>→h<sup>-</sup>→π<sup>0</sup>ν<sub>τ</sub>)
No full textUsing data from the CLEO II detector at the Cornell Electron Storage Ring, we measure scrB(τ<sup>-</sup>→h<sup>-</sup>→π<sup>0</sup>ν<sub>τ</sub> where h<sup>-</sup> refers to either π<sup>-</sup> or K<sup>-</sup>. We use three different methods to measure this branching fraction. The combined result is scrB(τ<sup>-</sup>→h<sup>-</sup>→π<sup>0</sup>ν<sub>τ</sub>=0.2587±0.0012±0.0042, in good agreement with standard model pr
Supersymmetry effects on the exclusive semileptonic decays B→πτ<SUP>+</SUP>τ<SUP>-</SUP> and B→ρτ<SUP>+</SUP>τ<SUP>-</SUP>
No full textSemileptonic decays of B mesons are known to be very sensitive to any new physics effects. Amongst various possibilities the transition at the quark level b→d1+1- is more suited than b→s1+1- for the purpose of studying CP violation. Here in this work we will discuss the effects of supersymmetry on the various experimentally measurable quantities such as the decay rate, forward backward asymmetry, various polarization asymmetries, and CP violation asymmetries in the exclusive channels B→π1+1- and B→ρ1+1-. We will focus mainly on the neutral Higgs boson effects on these measurements, with a view to eliciting information about possible CP violating as well as non-Hermitian terms in the effective Hamiltonian
