Abstract

The absolute inclusive branching fraction of D{sub s}{sup +}{r_arrow}{phi}X{sup +} has been measured from data collected by the BES detector at a center-of-mass energy of 4.03 GeV, corresponding to an integrated luminosity of 22.3 pb{sup {minus}1}. At this energy, direct pair production e{sup +}e{sup {minus}}{r_arrow}D{sub s}{sup +}D{sub s}{sup {minus}} has been observed. We have selected D{sub s} candidate events by reconstructing five hadronic decay modes D{sub s}{sup +}{r_arrow}{phi}{pi}{sup +}, {bar K}{sup 0{asterisk}}K{sup +}, {bar K}{sup 0}K{sup +}, f{sub 0}{pi}{sup +} and K{sup 0}K{sup {minus}}{pi}{sup +}{pi}{sup +} and have searched for inclusive {phi}{close_quote}s in the recoiling D{sub s}{sup {minus}}. We observed three recoiling {phi}{close_quote}s in the 166.4 {plus_minus} 31.8 D{sub s} candidate events, which leads to the absolute branching fraction B(D{sub s}{sup +}{r_arrow}{phi}X{sup +})=(17.8{sub {minus}7.2}{sup +15.1}{sub {minus}6.3}{sup +0.6}) {percent} and B(D{sub s}{sup +}{r_arrow}{phi}{pi}{sup +})=(3.6{sub {minus}1.6}{sup +3.1}{sub {minus}1.3}{sup +0.4}) {percent}. {copyright} {ital 1997} {ital The American Physical Society}

Measurements of {ital B}{r_arrow}{ital D}{sup +}{sub {ital s}}{ital X} decays

Journal Article CLEO Collaboration - Physical Review, D

This paper describes new measurements from CLEO of the inclusive {ital B}{r_arrow}{ital D}{sub {ital s}}{sup +}{ital X} branching fraction as well as the {ital B}{sup +}{r_arrow}{ital D}{sub {ital s}}{sup ({asterisk})+}{bar {ital D}}{sup ({asterisk})0} and {ital B}{sup 0}{r_arrow}{ital D}{sub {ital s}}{sup ({asterisk})+}{ital D}{sup ({asterisk}){minus}} branching fractions.

Measurement of the branching fraction of D{sub s} inclusive semileptonic decay D{sub s}{sup +}{r_arrow}e{sup +}X

Journal Article Bai, J Z ; Bian, J G ; Chai, Z W ; ... - Physical Review, D

The absolute inclusive semileptonic branching fraction of the D{sub s} meson has been measured based on 22.3 pb{sup {minus}1} of e{sup +}e{sup {minus}} collision data collected with the Beijing Spectrometer at {radical} (s) =4.03GeV. At this energy, the D{sub s} are produced in pairs: e{sup +}e{sup {minus}}{r_arrow}D{sub s}{sup +}D{sub s}{sup {minus}}. We reconstructed 171{plus_minus}21{plus_minus}15 D{sub s} events in five hadronic decay modes. In the recoil system of these events, several D{sub s} inclusive semileptonic decays were observed and the branching fraction is estimated to be B(D{sub s}{sup +}{r_arrow}e{sup +}X)=(7.7{sub {minus}4.3{minus}2.1}{sup +5.7+2.4}){percent}. {copyright} {ital 1997} {ital The American Physical Society}

Search for the Pentaquark via the P{sup 0}{sub {bar c}s}{r_arrow}{phi}{pi}p Decay

Journal Article Amato, S ; Anjos, J C ; Bediaga, I ; ... - Physical Review Letters

We report results of the first search for the pentaquark P{sub {bar c}s} which is predicted to be a doublet of states: P{sup 0}{sub {bar c}s}={vert_bar} {bar c}suud{r_angle} and P{sup {minus}}{sub {bar c}s}={vert_bar} {bar c}sddu{r_angle} . A search was made for the decay P{sup 0}{sub {bar c}s}{r_arrow} {phi}{pi}p in data from Fermilab experiment E791, in which a 500 GeV/c {pi}{sup {minus}} beam interacted with nuclear targets. We present upper limits at 90{percent} confidence level for the ratio of cross section times branching fraction of this decay to that for the decay D{sup {plus_minus}}{sub s}{r_arrow}{phi}{pi}{sup {plus_minus} } .

CP violation in the exclusive decays B{r_arrow}{pi}e{sup +}e{sup {minus}} and B{r_arrow}{rho}e{sup +}e{sup {minus}}

Journal Article Krueger, F ; Sehgal, L M - Physical Review, D

As a sequel to the calculation of the CP-violating asymmetry in the decay rates of b{r_arrow}dl{sup +}l{sup {minus}} and {bar b}{r_arrow}{bar d}l{sup +}l{sup {minus}}, we address in this paper the asymmetry in exclusive channels {bar B}{r_arrow}{pi}e{sup +}e{sup {minus}} and {bar B}{r_arrow}{rho}e{sup +}e{sup {minus}}, using form factors from two different models. In the invariant mass region 1GeV{lt}{radical} (s) {lt}M{sub J/{psi}}, the partial width asymmetry in the channel {bar B}{r_arrow}{pi} is {minus}6{percent} ({minus}2{percent}), and that in the channel {bar B}{r_arrow}{rho}, for one choice of form factors, is {minus}5{percent} ({minus}2{percent}), assuming Cabibbo-Kobayashi-Maskawa parameters {eta}=0.34, {rho}=0.3 ({minus}0.3).

Relations between the K{sub l3} and {tau}{r_arrow}K{pi}{nu}{sub {tau}} decays

Journal Article Lichard, P ; Institute of Physics, Silesian University, 746-01 Opava - Physical Review, D

We investigate the relations between the K{sub l3} and {tau}{r_arrow}K{pi}{nu}{sub {tau}} decays using the meson dominance approach. First, the experimental branching fractions (BF) for K{sub e3}{sup {plus_minus}} and K{sub e3}{sup 0} are used to fix two normalization constants (isospin invariance is not assumed). Then, the BF of {tau}{sup {minus}}{r_arrow}K{sup {asterisk}}(892){sup {minus}}{nu}{sub {tau}} is calculated in agreement with experiment. We further argue that the nonzero value of the slope parameter {lambda}{sub 0} of the K{sub {mu}3}{sup {plus_minus}} and K{sub {mu}3}{sup 0} form factors f{sub 0}(t) implies the existence of the {tau}{sup {minus}}{r_arrow}K{sub 0}{sup {asterisk}}(1430){sup {minus}}{nu}{sub {tau}} decay. We calculate its BF,more »« less
