Proposal for Testing Lepton Univerality in Upsilon Decays at a B Factory Running at Υ(3s) *

A proposal is presented for detecting new physics at a B factory running at the Υ(3S) resonance by testing lepton universality to the few percent level in the leptonic decays of the Υ(1S) and Υ(2S) resonances tagged by the dipion in the chain decay: Υ(3S) → π + π

Possibility of Exotic States in the Upsilon system

Recent data from Belle show unusually large partial widths Υ(5S) → Υ(1S)ππ and Υ(5S) → Υ(2S)ππ. The Z(4430) narrow resonance also reported by Belle in ψπ spectrum has the properties expected of a c̄cud̄ charged isovector tetraquark T c̄c . The analogous state T b̄b in the bottom sector might mediate anomalously large cascade decays in the Upsilon system, Υ(mS) → T b̄b π → Υ(nS)ππ, with a tetraquark-...

Heavy Quark Masses from the QQ̄ Threshold and the Upsilon Expansion

Recent results from studies using half the perturbative mass of heavy quark-antiquark n = 1, 3S1 quarkonium as a new heavy quark mass definition for problems where the characteristic scale is smaller than or of the same order as the heavy quark mass are reviewed. In this new scheme, called the 1S mass scheme, the heavy quark mass can be determined very accurately, and many observables like incl...

Observation of the Hadronic transitions chi(b1,2)(2P)-->omegaUpsilon(1S).

The CLEO Collaboration has made the first observations of hadronic transitions among bottomonium (bbmacr;) states other than the dipion transitions among Upsilon(nS) states. In our study of Upsilon(3S) decays, we find a significant signal for Upsilon(3S)-->gammaomegaUpsilon(1S) that is consistent with radiative decays Upsilon(3S)-->gammachi(b1,2)(2P), followed by chi(b1,2)(2P)-->omegaUpsilon(1S...

B Decays -measurements and Predictions * 1 Basic Methods on Upsilon-4s Resonance

Hadronic decays of B mesons are reviewed. First, masses of B mesons and observed patterns together with physics behind them are discussed. Then the effective Hamiltonian responsible for major decays is presented and its practical applications are discussed in the context of factorization. Various tests of factorization are then studied. For rare decays, the focus is placed on Kπ, ππ final state...

Observation of Upsilon(2S)-->etaUpsilon(1S) and search for related transitions.

We report the first observation of Upsilon(2S)-->etaUpsilon(1S), with a branching fraction B=(2.1(-0.6)+0.7(stat)+/-0.3(syst)) x 10(-4) and a statistical significance 5.3sigma. Data were acquired with the CLEO III detector at the CESR e+e(-) symmetric collider. This is the first process observed involving a b-quark spin flip. For related transitions, 90% confidence limits in units of 10(-4) are...
