The spinless Bethe-Salpeter equation is solved for three attractive static quark-antiquark potentials of the form V(r) = -ar(-beta)+br(beta)+c, 0 < beta less-than-or-equal-to 1, and the effective non-Coulombic power-law potential of the. form V(r)=ar 0.1+c to obtain the spin-averaged energy levels in bottomonium UPSILON(bbBAR) and charmonium psi(ccBAR) families. The shifted 1/N expansion technique is used. Calculations of the energy eigenvalues are carried out up to third order and parameters of each potential are adjusted to obtain the best agreement with the experimental spin-averaged data (SAD). Flavor-dependent and flavor-independent cases are considered in this work.

Measurement of the differential cross section and charge asymmetry for inclusive pp -> W-+/- + X production at root s=8 TeV Khachatryan, V. y; et. al. (Springer Science and Business Media LLC, 2016-08-01) The differential cross section and charge asymmetry for inclusive pp -> W-+/- + X -> mu(+/-)nu + X production at root s = 8 TeV are measured as a function of muon pseudorapidity. The data sample corresponds to an integrated luminosity of 18.8 fb(-1) recorded with the CMS detector at the LHC. These results provide important constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable x from 10(-3) to 10(-1).
Jet and underlying event properties as a function of charged-particle multiplicity in proton-proton collisions at root s=7 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-12-01) Characteristics of multi-particle production in proton-proton collisions at root s = 7 TeV are studied as a function of the charged-particle multiplicity, N (ch). The produced particles are separated into two classes: those belonging to jets and those belonging to the underlying event. Charged particles are measured with pseudorapidity |eta| 0.25 GeV/c. Jets are reconstructed from charged-particles only and required to have p (T)> 5 GeV/c. The distributions of jet p (T), average p (T) of charged particles b...
Double-lepton polarization asymmetries in the B -> Kl(+)l(-) decay beyond the standard model Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2004-06-01) General expressions for the double-lepton polarizations in the B --> Kl(+)l(-)decay are obtained, using a model independent effective Hamiltonian, including all possible interactions. Correlations between the averaged double-lepton polarization asymmetries and the branching ratio, as well as the averaged single-lepton polarization asymmetry are studied. It is observed that a study of the double-lepton polarization asymmetries can serve as a good test for establishing new physics beyond the standard model.
Radiation in Yang-Mills Formulation of Gravity and a Generalized pp-Wave Metric Başkal, Sibel (Oxford University Press (OUP), 1999-10-1) Variational methods applied to a quadratic Yang-Mills-type Lagrangian yield two sets of relations interpreted as the field equations and the energy-momentum tensor for the gravitational field. A covariant condition is imposed on the energy-momentum tensor in order for it to represent the radiation field. A generalized pp-wave metric is found to simultaneously satisfy both the field equations and the radiation condition. The result is compared with that of Lichnerowicz.
Accelerated Levi-Civita-Bertotti-Robinson metric in D dimensions Gurses, M; Sarıoğlu, Bahtiyar Özgür (Springer Science and Business Media LLC, 2005-12-01) A conformally flat accelerated charge metric is found in an arbitrary dimension D. It is a solution of the Einstein-Maxwell-null fluid equations with a cosmological constant in D >= 4 dimensions. When the acceleration is zero, our solution reduces to the Levi-Civita-Bertotti-Robinson metric. We show that the charge loses its energy, for all dimensions, due to the acceleration.
