<Title>Search for the decay phi -> K0-K0bar-gamma with the KLOE experiment</Title> <Authors>Ambrosino, F.; Antonelli, A.; Antonelli, M.; Archilli, F.; Beltrame, P.; Bencivenni, G.; Bertolucci, S.; Bini, C.; Bloise, C.; Bocchetta, Serena; Bossi, F.; Branchini, P.; Capon, G.; Capussela, T.; Ceradini, Filippo; Ciambrone, P.; De Lucia, E.; De Santis, A.; De Simone, P.; De Zorzi, G.; Denig, A.; Di Domenico, A.; Di Donato, C.; Di Micco, Biagio; Dreucci, M.; Felici, G.; Fiore, S.; Franzini, P.; Gatti, C.; Gauzzi, P.; Giovannella, S.; Graziani, E.; Lanfranchi, G.; Lee-Franzini, J.; Martini, M.; Massarotti, P.; Meola, S.; Miscetti, S.; Moulson, M.; Mueller, S.; Murtas, F.; Napolitano, M.; Nguyen, Federico; Palutan, M.; Pasqualucci, E.; Passeri, A.; Patera, V.; Santangelo, P.; Sciascia, B.; Spadaro, T.; Testa, M.; Tortora, L.; Valente, P.; Venanzoni, G.; Versaci, R.; Xu, G.</Authors> <Issue Date>2009-07</Issue Date> <Is part of>Physics Letters B</Is part of> <Volume>679</Volume> <Pages>10-14</Pages> <Abstract>We have searched for the decay phi -> K0-K0bar-gamma by detecting KS pairs plus a photon and with the KS-mesons decaying to pi+ pi-, in a sample of about 1.5 x 10^9 phi-decays collected by the KLOE experiment at DAFNE. The reaction proceeds through the intermediate states f0(980)-gamma, a0(980)-gamma. We find five events with 3.2 events expected from background processes. We obtain the upperlimit: BR(phi -> K0-Kobar-gamma < 1.9 x 10^(-8) at 90% CL.</Abstract>

<Title>Precise measurement of Gamma(K -> e nu(gamma))/Gamma(K -> mu nu(gamma))and study of K -> e nu gamma</Title> <Authors>Ambrosino, F.; Antonelli, A.; Antonelli, M.; Archilli, F.; Beltrame, P.; Bencivenni, G.; Bini, C.; Bloise, C.; Bocchetta, Serena; Bossi, F.; Branchini, P.; Capon, G.; Capriotti, D.; Capussela, T.; Ceradini, Filippo; Ciambrone, P.; De Lucia, E.; De Santis, A.; De Simone, P.; De Zorzi, G.; Denig, A.; Di Domenico, A.; Di Donato, C.; Di Micco, Biagio; Dreucci, M.; Felici, G.; Fiore, S.; Franzini, P.; Gatti, C.; Gauzzi, P.; Giovannella, S.; Graziani, E.; Jacewicz, M.; Kulikov, V.; Lanfranchi, G.; Lee-Franzini, J.; Martini, M.; Massarotti, P.; Meola, S.; Miscetti, S.; Moulson, M.; Mueller, S.; Murtas, F.; Napolitano, M.; Nguyen, Federico; Palutan, M.; Passeri, A.; Patera, V.; Santangelo, P.; Sciascia, B.; Sibidanov, A.; Spadaro, T.; Tortora, L.; Valente, P.; Venanzoni, G.; Versaci, R.</Authors> <Issue Date>2009-12</Issue Date> <Is part of>European Physical Journal C</Is part of> <Volume>64</Volume> <Pages>627-636</Pages> <Abstract>We present a precise measurement of the ratio R-K = Gamma(K -> enu(gamma))/Gamma(K -> mu nu(gamma)) and a study of the radiativeprocess K -> e nu gamma, performed with the KLOE detector. The resultsare based on data collected at the Frascati e(+)e(-) collider DA Phi NEfor an integrated luminosity of 2.2 fb(-1). We find R-K = (2.493 +/-0.025(stat) +/- 0.019(syst)) x 10(-5), in agreement with the StandardModel expectation. This result is used to improve constraints onparameters of the Minimal Supersymmetric Standard Model with leptonflavor violation. We also measured the differential decay rate dGamma(K -> e nu gamma)/dE(gamma) for photon energies 10 < E-gamma < 250MeV. Results are compared with predictions from theory.</Abstract>
