We calculate the decay rate ratios for OZI allowed decays of Υ(5S) to two B mesons by using the decay amplitudes which incorporate the wave function of the Υ(5S) state. We obtain the results that the branching ratio of the Υ(5S) decay to B∗ sB ∗ s is much larger than the branching ratio to BsB ∗ s or BsB ∗ s , in good agreement with recent experimental results of CLEO and BELLE. This agreement ...

In a canonical way, one can think of B as “two-parameter Brownian motion”. In this article, we address the following question: “Given a measurable function υ : R → R+, what can be said about the distribution of ∫ [0,1]2 υ(Bs) ds?” The one-parameter variant of this question is both easy-to-state and well understood. Indeed, if b designates standard Brownian motion, the Laplace transform of ∫ 1 0...

Rough set theory is introduced into linear υ support vector machine (svm), and rough marginbased linear υ svm is proposed in this paper. By constructing rough lower margin, rough upper margin and rough boundary in linear υ svm, then we maximize the rough margin not margin in linear υ svm. Thus more points are considered in constructing the separating hyper-plane than those used in linear υ svm....

The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of 150 μb(-1) and 230 nb(-1), respectively, collected in 2011 by the CMS experiment at the LHC, at a center-of-mass energy per nucleon pair of 2.76 TeV. The Υ(nS) yields are measured from...

Let E be an elliptic curve over a number field K. Let h be the logarithmic (or Weil) height on E and ĥ be the canonical height on E. Bounds for the difference h − ĥ are of tremendous theoretical and practical importance. It is possible to decompose h − ĥ as a weighted sum of continuous bounded functions Ψυ : E(Kυ) → R over the set of places υ of K. A standard method for bounding h− ĥ, (due to L...

We present the first observation of the bottomonium ground state ηb(1S) in the photon energy spectrum using a sample of (109 ± 1) million of Υ(3S) events recorded at the Υ(3S) energy with the BaBar detector at the PEP-II B factory at SLAC. A peak at Eγ = 921.2 +2.1 −2.8(stat) ± 2.4(syst) MeV observed with a significance of 10 standard deviations in the photon energy spectrum is interpretated as...

Properties of bottomonia (Υ,χb, and Υ ′) in the quark-gluon plasma (QGP) are investigated by assessing inelastic reaction rates and their interplay with open-bottom states (b quarks or B mesons) and color screening. The latter leads to vanishing quarkonium-binding energies at sufficiently high temperatures (close to the dissolution point), which, in particular, renders standard gluo-dissociatio...

We study the radiative decay of Υ into a scalar glueball Υ → γGs using QCD factorization. We find that for this process the non-perturbative effects can be factorized into a matrix element defined in non-relativistic QCD which can be determined from leptonic decay of Υ, and into the gluon parton distribution amplitude, whose asymptotic form is known up to a normalization constant. Normalizing t...

The so-called Prüfer υ-multiplication domains PυMDs are usually defined as domains whose finitely generated nonzero ideals are t-invertible. These domains generalize Prüfer domains and Krull domains. The PυMDs are relatively obscure compared to their verywell-known special cases. One of the reasons could be that the study of PυMDs uses the jargon of star operations, such as the υ-operation and ...
