Abstract

Analyzing {upsilon}(nS) decays acquired with the CLEO detector operating at the CESR e{sup +}e{sup -} collider, we measure for the first time the product branching fractions B[{upsilon}(nS){yields}{gamma}{chi}{sub bJ}((n-1)P)]B[{chi}{sub bJ}(n-1)P){yields}X{sub i}] for n=2 and 3, where X{sub i} denotes, for each i, one of the 14 exclusive light-hadron final states for which we observe significant signals in both {chi}{sub bJ}(1P) and {chi}{sub bJ}(2P) decays. We also determine upper limits for the electric dipole (E1) transitions {upsilon}(3S){yields}{gamma}{chi}{sub bJ}(1P)

Measurements of branching fractions for electromagnetic transitions involving the {chi}{sub bJ}(1P) states

Journal Article Kornicer, M; Mitchell, R; Tarbert, C; ... - Physical Review. D, Particles Fields

Using (9.32, 5.88) million {Upsilon}(2S,3S) decays taken with the CLEO III detector, we obtain five product branching fractions for the exclusive processes {Upsilon}(2S){yields}{gamma}{chi}{sub b0,1,2}(1P){yields}{gamma}{gamma}{Upsilon}(1S) and {Upsilon}(3S){yields}{gamma}{chi}{sub b1,2}(1P){yields}{gamma}{gamma}{Upsilon}(1S). We observe the transition {chi}{sub b0}(1P){yields}{gamma}{Upsilon}(1S) for the first time. Using the known branching fractions for B[{Upsilon}(2S){yields}{gamma}{chi}{sub bJ}(1P)], we extract values for B[{chi}{sub bJ}(1P){yields}{gamma}{Upsilon}(1S)] for J=0, 1, 2. In turn, these values can be used to unfold the {Upsilon}(3S) product branching fractions to obtain values for B[{Upsilon}(3S){yields}{gamma}{chi}{sub b1,2}(1P)] for the first time individually. Comparison of these with each other and with the branching fraction B[{Upsilon}(3S){yields}{gamma}{chi}{sub b0}] previously measured by CLEO provides tests ofmore »« less

Experimental study of {chi}{sub b}(2P){yields}{pi}{pi}{chi}{sub b}(1P)

Journal Article Cawlfield, C; Eisenstein, B; Karliner, I - Physical Review. D, Particles Fields

We have searched for the di-pion transition {chi}{sub b}(2P){yields}{pi}{pi}{chi}{sub b}(1P) in the CLEO III sample of {upsilon}(3S) decays in the exclusive decay chain: {upsilon}(3S){yields}{gamma}{chi}{sub b}(2P), {chi}{sub b}(2P){yields}{pi}{pi}{chi}{sub b}(1P), {chi}{sub b}(1P){yields}{gamma}{upsilon}(1S), {upsilon}(1S){yields}l{sup +}l{sup -}. Our studies include both {pi}{sup +}{pi}{sup -} and {pi}{sup 0}{pi}{sup 0}, each analyzed both in fully-reconstructed events and in events with one pion undetected. We show that the null hypothesis is not substantiated. Under reasonable assumptions, we find the partial decay width to be {gamma}({chi}{sub b}(2P){yields}{pi}{pi}{chi}{sub b}(1P))=(0.83{+-}0.22{+-}0.08{+-}0.19) keV, with the uncertainties being statistical, internal CLEO systematics, and common systematics from outside sources.

Study of di-pion Bottomonium Transitions and Search for the h_b(1P) State

Journal Article Lees, J; Poireau, V; Tisserand, V; ... - Phys.Rev.D84:011104,2011

We study inclusive di-pion decays using a sample of 108 x 10{sup 6} {Upsilon}(3S) events recorded with the BABAR detector. We search for the decay mode {Upsilon}(3S) {yields} {pi}{sup +}{pi}{sup -}h{sub b} (1P) and find no evidence for the bottomonium spin-singlet state h{sub b}(1P) in the invariant mass distribution recoiling against the {pi}{sup +}{pi}{sup -} system. Assuming the h{sub b}(1P) mass to be 9.900 GeV/c{sup 2}, we measure the upper limit on the branching fraction {Beta}[{Upsilon}(3S) {yields} {pi}{sup +}{pi}{sup -}h{sub b}(1P)] < 1.2 x 10{sup -4}, at 90% confidence level. We also investigate the {chi}{sub bJ}(2P) {yields} {pi}{sup +}{pi}{sup -}more »« less

CLEO Results From {upsilon} Decays

Journal Article Crede, V - AIP Conference Proceedings

Decays of the narrow {upsilon} resonances have been studied with the CLEO-III detector. Among other things, inclusive photon spectra in {upsilon}(2S) and {upsilon}(3S) decays using a large statistics data sample have been obtained. The most precise measurements of electric dipole (E1) photon transition rates and photon energies for {upsilon}(2S) {yields} {gamma}{chi}bJ(1P) and {upsilon}(3S) {yields} {gamma}{chi}bJ(2P) (J = 0, 1, 2) are presented. The rare E1 transition {upsilon}(3S) {yields} {gamma}{chi}b0(1P) has been measured for the first time.

Evidence for the h{sub b}(1P) meson in the decay {Upsilon}(3S){yields}{pi}{sup 0}h{sub b}(1P)

Journal Article Lees, J; Poireau, V; Prencipe, E; ... - Physical Review. D, Particles Fields

Using a sample of 122x10{sup 6} {Upsilon}(3S) events recorded with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC, we search for the h{sub b}(1P) spin-singlet partner of the P-wave {chi}{sub bJ}(1P) states in the sequential decay {Upsilon}(3S){yields}{pi}{sup 0}h{sub b}(1P), h{sub b}(1P){yields}{gamma}{eta}{sub b}(1S). We observe an excess of events above background in the distribution of the recoil mass against the {pi}{sup 0} at mass 9902{+-}4(stat){+-}2(syst) MeV/c{sup 2}. The width of the observed signal is consistent with experimental resolution, and its significance is 3.1{sigma}, including systematic uncertainties. We obtain the value (4.3{+-}1.1(stat){+-}0.9(syst))x10{sup -4} for the product branchingmore »« less
