Abstract

Using data collected by the CLEO II detector at a center-of-mass energy on or near the {Upsilon}(4S) resonance, we have determined the 90% confidence level upper limit {Beta}({bar B} {yields} {Lambda}{sub c}{sup +}e{sup -} X)/{Beta}({bar B} {yields} ({Lambda}{sub c}{sup +} or {bar {Lambda}}{sub c}{sup -})X) < 0.05 for electrons with momentum above 0.6 GeV/c. We have also obtained the limit {Beta}(B{sup -} {yields} {Lambda}{sub c}{sup +}{bar p}e{sup -}{bar {nu}}{sub e})/{Beta}({bar B} {yields} {Lambda}{sub c}{sup +}{bar p}X) < 0.04 at the 90% confidence level and measured the ratio {Beta}({bar B} {yields} {Lambda}{sub c}{sup +}{bar p}X)/{Beta}({bar B} {yields} ({Lambda}{sub c}{sup +} or {bar {Lambda}}{sub c}{sup -})X) = 0.57 {+-} 0.05 {+-} 0.05.

Sigma. sub c production from e sup + e sup minus annihilation in the. Upsilon. energy region

Miscellaneous Letson, T

This dissertation presents results of a study of {Sigma}{sub c} production in the {Upsilon} energy region. The experiment was performed at the Cornell Electron Storage Ring using the CLEO detector, the CLEO detector is a large-aperture magnetic detector. Previous experiments have presented inconsistent values for the mass difference M({Sigma}{sub c}{sup 0}) - M({Lambda}{sub c}{sup +}) differing by 10.8 MeV/c{sup 2}, while agreeing on the value for M({Sigma}{sub c}{sup ++}) - M({Lambda}{sub c}{sup +}). This analysis measures both of these mass differences. The author finds M({Sigma}{sub c}{sup ++}) - M({Lambda}{sub c}{sup +}) {equals} 167.8 {+-} 0.5 {+-} 0.3 MeV/c{sup 2}, whichmore »« less
Observation of Exclusive B Decays to Final States Containing a Charmed Baryon

Technical Report Jessop, Colin

Using data collected in the region of the {Upsilon}(4S) resonance with the CLEO-II detector, they report on the first observation of exclusive decays of the B meson to final states with a charmed baryon. They have measured the branching fractions {Beta}(B{sup -} {yields} {Lambda}{sub c}{sup +}{bar p}{pi}{sup -}) = (0.62{sub -0.20}{sup +0.23} {+-} 0.11 {+-} 0.10) x 10{sup -3} and {Beta}({bar B}{sup 0} {yields} {Lambda}{sub c}{sup +}{bar p}{pi}{sup +}{pi}{sup -}) = (1.33{sub -0.42}{sup +0.46} {+-} 0.31 {+-} 0.21) x 10{sup -3}. In addition, they report upper limits for final states of the form {bar B} {yields} {Lambda}{sub c}{sup +}{bar p}(n{pi})more »« less

Journal Article Park, K; Choi, Y; Choi, Y; ... - Physical Review. D, Particles Fields

We study the three-body charmed baryonic decays B{sup 0}{yields}{sigma}{sub c}{sup ++}p{pi}{sup -} and B{sup 0}{yields}{sigma}{sub c}{sup 0}p{pi}{sup +} in the four-body final state B{sup 0}{yields}{lambda}{sub c}{sup +}p{pi}{sup +}{pi}{sup -}, using a data sample of 357 fb{sup -1} accumulated at the {upsilon}(4S) resonance with the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider. We measure the branching fractions B(B{sup 0}{yields}{sigma}{sub c}(2455){sup ++}p{pi}{sup -})=(2.1{+-}0.2{+-}0.3{+-}0.5)x10{sup -4}, B(B{sup 0}{yields}{sigma}{sub c}(2455){sup 0}p{pi}{sup +})=(1.4{+-}0.2{+-}0.2{+-}0.4)x10{sup -4} and B(B{sup 0}{yields}{sigma}{sub c}(2520){sup ++}p{pi}{sup -})=(1.2{+-}0.1{+-}0.2{+-}0.3)x10{sup -4} with signal significances of 13.1{sigma}, 9.4{sigma} and 7.1{sigma}, respectively.

Study of Branching Fractions and CP-Violating Asymmetries in B Meson Decays to Rho And Pion Final State with the BABAR Detector

Technical Report Wu, Jinwei

We present measurements of branching fractions and CP-violating asymmetries in B-meson decays to {rho}{sup +}{pi}{sup 0}, {rho}{sup 0}{pi}{sup +} and {rho}{sup 0}{pi}{sup 0}. The data sample comprises 89 x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We find the charge-averaged branching fractions {Beta}(B{sup +} {yields} {rho}{sup +}{pi}{sup 0}) = (10.9 {+-} 1.9(stat) {+-} 1.9(syst)) x 10{sup -6} and {Beta}(B{sup 0} {yields} {rho}{sup 0}{pi}{sup +}) = (9.5 {+-} 1.1 {+-} 0.9) x 10{sup -6}, and we set a 90% confidence-level upper limit {Beta}(B{sup 0} {yields} {rho}{sup 0}{pi}{sup 0})more »« less
