Measurement of the branching fraction for the decay
2002 We present a measurement of the branching ratio BR(K → π ± e ∓ ̄ ν ( ν )) performed using the KLOE detector. K S -mesons are produced in the reaction e + e − → φ → K S K L at the DA Φ NE collider. In a sample of ∼ 5 × 10 6 K S -tagged events we find 624 ± 30 semileptonic K S decays.Normalizing to the K S → π + π − count in the same data sample, we ...A., Aloisio, F., Ambrosino, A., Andryakov, A., Antonelli, M., Antonelli, C., Bacci, G., Bencivenni, S., Bertolucci, C., Bini, C., Bloise, V., Bocci, F., Bossi, P., Branchini, S.

2004 We study the decays B+ → ηcK+ and B0 → ηcK0, where the ηc is reconstructed in the KS0K ±π∓ and K+K- π0 decay modes. Results are based on a sample of 86 B B̄ pairs collected with the BABAR detector at the SLAC e+e- B Factory. We measure the product of branching fractions B(B+ → ηcK+) ×B(ηc→KK̄π)= (7.40±0.50±0.70)×10-5 and B(B 0→ηcK0) ×B(ηc→KK̄π)=(6.48±0.AUBERT B, BARATE R, BOUTIGNY D, COUDERC F, GAILLARD JM, HICHEUR A, KARYOTAKIS Y, LEES JP, TISSERAND V, ZGHICHE A, PALANO A, POMPILI A, CHEN JC, QI ND, RONG G, WANG P, ZHU YS, EIGEN G, OFTE I, STUGU B, ABRAMS GS, BORGLAND AW, BREON AB, BROWN DN, BUTTON SHAFER J, CAHN RN, CHARLES E, DAY CT, GILL MS, GRITSAN AV, GROYSMAN Y, JACOBSEN RG, KADEL RW, KADYK J, KERTH LT, KOLOMENSKY YG, KUKARTSEV G, LECLERC C, LEVI ME, LYNCH G, MIR LM, ODDONE PJ, ORIMOTO TJ, PRIPSTEIN M, ROE NA, RONAN MT, SHELKOV VG, TELNOV AV, WENZEL WA, FORD K, HARRISON TJ, HAWKES CM, MORGAN SE, WATSON AT, WATSON NK, FRITSCH M, GOETZEN K, HELD T, KOCH H, LEWANDOWSKI B, PELIZAEUS M, STEINKE M, BOYD JT, CHEVALIER N, COTTINGHAM WN, KELLY MP, LATHAM TE, WILSON FF, ABE K, CUHADAR DONSZELMANN T, HEARTY C, MATTISON TS, MCKENNA JA, THIESSEN D, KYBERD P, TEODORESCU L, BLINOV VE, BUKIN AD, DRUZHININ VP, GOLUBEV VB, IVANCHENKO VN, KRAVCHENKO EA, ONUCHIN AP, SEREDNYAKOV SI, SKOVPEN YI, SOLODOV EP, YUSHKOV AN, BEST D, BRUINSMA M, CHAO M, ESCHRICH I, KIRKBY D, LANKFORD AJ, MANDELKERN M, MOMMSEN RK, ROETHEL W, STOKER DP, BUCHANAN C, HARTFIEL BL, GARY JW, SHEN BC, WANG K, DEL RE D, HADAVAND HK, HILL EJ, MACFARLANE DB, PAAR HP, RAHATLOU S, SHARMA V, BERRYHILL JW, CAMPAGNARI C, DAHMES B, LEVY SL, LONG O, LU A, MAZUR MA, RICHMAN JD, VERKERKE W, BECK TW, EISNER AM, HEUSCH CA, LOCKMAN WS, SCHALK T, SCHMITZ RE, SCHUMM BA, SEIDEN A, SPRADLIN P, WILLIAMS DC, WILSON MG, ALBERT J, CHEN E, DUBOIS FELSMANN GP, DVORETSKII A, HITLIN DG, NARSKY I, PIATENKO T, PORTER FC, RYD A, SAMUEL A, YANG S, JAYATILLEKE S, MANCINELLI G, MEADOWS BT, SOKOLOFF MD, ABE T, BLANC F, BLOOM P, CHEN S, CLARK PJ, FORD WT, NAUENBERG U, OLIVAS A, RANKIN P, SMITH JG, VAN HOEK WC, ZHANG L, HARTON JL, HU T, SOFFER A, TOKI WH, WILSON RJ, ALTENBURG D, BRANDT T, BROSE J, COLBERG T, DICKOPP M, FELTRESI E, HAUKE A, LACKER HM, MALY E, MULLER PFEFFERKORN R, NOGOWSKI R, OTTO S, SCHUBERT J, SCHUBERT KR, SCHWIERZ R, SPAAN B, BERNARD D, BONNEAUD GR, BROCHARD F, GRENIER P, THIEBAUX C, VASILEIADIS G, VERDERI M, BARD DJ, KHAN A, LAVIN D, MUHEIM F, PLAYFER S, ANDREOTTI M, AZZOLINI V, BETTONI D, BOZZI C, CALABRESE R, CIBINETTO G, LUPPI E, NEGRINI M, PIEMONTESE L, SARTI A, TREADWELL E, PALOMBO F, MARGONI, MARTINO, SIMONETTO, FRANCO, STROILI, ROBERTO, NERI N, SIMI, GABRIELE +205 moreopenaire +4 more sources
