Title: PSI(2S) Two- and Three-Body Hadronic Decays

Abstract

The authors report measurements of branching fractions for {psi}(2S) decays into {omega}{pi}{sup +} {pi}{sup -}, b{sub 1}{pi}, {omega}f{sub 2}(1270), {omega}K{sup +}K{sup -}, {omega}p{bar p}, {phi}{pi}{sup +}{pi}{sup -}, {phi}f{sub 0}(980), {phi}K{sup +} K{sup -}, and an upper limit for {phi}p{bar p} final states based on a data sample of (4.02 {+-} 0.22) x 10{sup 6} {psi}(2S) events collected with the BESI detector at the Beijing Electron-Positron Collider. The branching fractions for b{sub 1}{pi} and {omega}f{sub 2}(1270) update previous BES results, while those for other decay modes are first measurements. The ratios of {psi}(2S) and J/{psi} branching fractions are smaller than what is expected from the 12% rule by a factor of six for {omega}f{sub 2}(1270), by a factor of two for {omega}{pi}{sup +} {pi}{sup -}, {omega}p{bar p}, and {phi}K{sup +} K{sup -}, while for other studied channels the ratios are consistent with expectation within errors.

  • This paper describes the observation of the decays B{sup {plus}} {r_arrow} {psi}(2S)K{sup {plus}} and B{sup 0} {r_arrow} {psi}(2S)K{sup {asterisk}}(892){sup 0} in 1.8 TeV p{ovr p} collisions and presents measurements of the branching fractions Br(B{sup {plus}} {r_arrow} {psi}(2S)K{sup {plus}}) and Br(B{sup 0} {r_arrow} {psi}(2S)K{sup {asterisk}}(892){sup 0}) relative to Br(B{sup {plus}} {r_arrow} J/{psi}K{sup {plus}}) and Br(B{sup 0} {r_arrow} J/{psi}K{sup {asterisk}}(892){sup 0}), respectively. The {psi}(2S) mesons are reconstructed in both the {psi}(2S) {r_arrow} {mu}{sup {plus}}{mu}{sup {minus}} and {psi}(2S) {r_arrow} J/{psi}{pi}{sup {plus}}{pi}{sup {minus}} channels. The world average branching fractions for the J/{psi} channels are used to extract the absolute branching fractions Br(B{sup {plus}} {r_arrow}more » {psi}(2S)K{sup {plus}}) = (6.8{plus_minus}1.0(stat.){plus_minus}1.4(syst.)){times}10{sup {minus}4} and Br(B{sup 0} {r_arrow} {psi}(2S)K{sup {asterisk}}(892){sup 0}) = (9.0{plus_minus}2.1(stat.){plus_minus}2. 0(syst.)){times}10{sup {minus}4}. 9 refs., 13 figs., 8 tabs.« less

  • Preliminary results are presented on a search for several exclusive charmless hadronic B decays, from data collected by the BABAR detector near the {Upsilon}(4S) resonance. These include two-body decay modes h{sup {+-}}h{sup {-+}}, three-body decay modes with final states h{sup {+-}}h{sup {-+}}h{sup {+-}} and h{sup {+-}}h{sup {-+}}{pi}{sup 0}, and quasi-two-body decay modes with final states X{sup 0}h and X{sup 0}K{sub s}{sup 0}, where h = {pi} or K and X{sup 0} = {eta}' or {omega}. The measurement of branching fractions for four decay modes, and upper limits for nine modes are presented.

  • In these lectures the authors discuss the impact of soft hadronic physics on predictions for B decays. Unfortunately their tools for calculating these effects are limited; even after the use of the best available tools the resulting theoretical uncertainties are difficult to delimit, and can obscure tests for the presence of beyond-Standard-Model physics. The first lecture reviews what tools are available, the second reviews in more detail two examples of how these tools can be used.

    Account is given for the observed enhancement of GAMMA(D/sup 0/ ..-->.. K/sup -/K/sup +/)/GAMMA(D/sup 0/ ..-->.. K/sup -/..pi../sup +/) and suppression of GAMMA(D/sup 0/ ..-->.. ..pi../sup -/..pi../sup +/)/GAMMA(D/sup 0/ ..-->.. K/sup -/..pi../sup +/) relative to tan /sup 2/theta/sub C/ in terms of the ratio f/sub K//f/sub ..pi../ of leptonic decay constants and different effective Cabibbo angles in noncharm and charm sectors. Strong new constraints on mixing angles in the six-quark model are implied. 18 references.

  • The authors present preliminary results of a search for several exclusive charmless hadronic B decays from electron-positron annihilation data collected by the BaBar detector near the Upsilon(4S) resonance. These include three-body decay modes with final states h{+-}h{sup minus-plus}h{+-} and h{+-}h{sup minus-plus}pi{sup 0}, and quasi-two-body decay modes with final states X{sup 0}h and X{sup 0}K{sub S}{sup 0}, where h = pi or K and X{sup 0} = eta-prime or omega. They find beta(B{sup 0} --> rho{sup minus-plus}pi{sup {+-}}) = (49{+-}13{sub {minus}5}{sup +6}) x 10{sup {minus}6} and beta(B{sup +} --> eta-prime-K{sup +}) = (62{+-}18{+-}8) x 10{sup {minus}6} and present upper limits formore » right other decays.« less
