AbstractAbstract
[en] In the framework of the relativistic quark model in the light-cone formalism, branching ratios of electromagnetic decays of mesons containing light quarks are calculated. The theoretical results are compared with the experimental data and with the results of the nonrelativistic potential model. 7 refs., 3 figs., 1 tab

AbstractAbstract
[en] The radiative decay constants corresponding to the Fulcher bands of the H2 molecular spectrum are obtained using pulsed-electron beam techniques. Data in the range approx.1.8 to 2.8 x 107 s-1 are obtained at 25 eV incident electron energy for the d 3π/sub u/ →a 3Σ+/sub g/ (v', v'') Q (K) and k 3π/sub u/ →a 3Σ+/sub g/ (v',v'') Q (K) rotational lines with K=1,2,3 and v'=0,1,2,3,→v''=0,1,2,3. Additional measurements of the d 3π/sub u/→a 3Σ/sub g/+(0,0) Q1 rotational line intensity indicate the presence of a two-mode decay over the energy range 50--300 eV. The long-lived decay component, identified as radiative cascade from upper levels, contributes approx.15% to the total d 3π/sub u/(v'=0) population

AbstractAbstract
[en] The radiative decay b → sγ is examined in the Standard Model and in nine classes of models which contain physics beyond the Standard Model. The constraints which may be placed on these models from the recent results of the CLEO Collaboration on both inclusive and exclusive radiative B decays is summarized. Reasonable bounds are found for the parameters in some cases

AbstractAbstract
[en] We find no evidence for ν/sub μ/ or anti ν/sub μ/ decays for any two-body decay mode in which a photon is emitted. The 90% confidence level limit which we set is tau ν/sub μ/Mν/sub μ/ > 0.11, where Mν/sub μ/ is the mass of the muon neutrino in eV and tau ν/sub μ/ is the muon neutrino lifetime in seconds
