SCET approach to top quark decay
Abstract In this work we study the QCD corrections to the top quark doubly decay rate with a detected B hadron containing a b quark. We focus on the regime among which the emitted W boson nearly carries its maximum energy. The tool that we use here...

Closing the light sbottom mass window from a compilation of e+e−→hadron data
Abstract The e+e−→hadron cross section data from PEP, PETRA, TRISTAN, SLC and LEP, at centre-of-mass energies between 20 to 209 GeV, are analysed to search for the production of a pair of light sbottoms decaying hadronically via R-parity-violating...

Left–right symmetric model of neutrino dark energy
Abstract We implemented the neutrino dark energy (νDE) proposal in a left–right symmetric model. Unlike earlier models of mass varying neutrinos, in the present model the mass parameter that depends on the scalar field (acceleron) remains very light ...

Universal properties of bulk viscosity near the QCD phase transition
Abstract We extract the bulk viscosity of hot quark–gluon matter in the presence of light quarks from the recent lattice data on the QCD equation of state. For that purpose we extend the sum rule analysis by including the contribution of light...

Anomalous U(1)'s masses in non-supersymmetric open string vacua
Abstract Anomalous U(1)'s are omnipresent in realizations of the Standard Model using D-branes. Such models are typically non-supersymmetric, and the anomalous U(1) masses are potentially relevant for experiment. In this Letter, the string...

Chiral effective model with the Polyakov loop
Abstract We discuss how the simultaneous crossovers of deconfinement and chiral restoration can be realized. We propose a dynamical mechanism assuming that the effective potential gives a finite value of the chiral condensate if the Polyakov loop...

Orbital electron capture decay of hydrogen- and helium-like 142Pm ions
Abstract The β + and orbital electron-capture decays of stored hydrogen- and helium-like 142Pm ions have been measured. So ...

One-loop weak corrections to γ/Z hadro-production at finite transverse momentum
Abstract We illustrate the effects of one-loop weak corrections onto the production of neutral gauge bosons of the Standard Model at RHIC-spin, Tevatron and LHC, in presence of quark/gluon radiation from the initial state. We find such effects to be ...

Description of positive and negative parity dipole bands within the extended coherent state model
Abstract The extended coherent state model is further extended as to describe two dipole bands of different parities. The formalism provides a consistent description of eight rotational bands. A unified description for spherical, transitional and...

ϒ production as a probe for early state dynamics in high energy nuclear collisions at RHIC
Abstract ϒ production in heavy ion collisions at RHIC energy is investigated. While the transverse momentum spectra of the ground state ϒ ( 1 ...

Exact scaling relations in relativistic hydrodynamic turbulence
Abstract We consider the steady state statistics of turbulence in general classes of dissipative hydrodynamic equations, where the fluctuations are sustained by a random source concentrated at large scales. It is well known that in some particular...

Neutron-induced fission cross sections of short-lived actinides with the surrogate reaction method
Abstract Neutron-induced fission cross sections for 242,243Cm and 241Am have been obtained with the surrogate reaction method. Recent results for the neutron-induced cross section of 243Cm are questioned by the present data. For the first time, the...

Monte Carlo model for the dynamic magnetization of microspheres
Abstract Monte Carlo method with a variable number of calculation steps is used for simulations of the magnetization dynamics in a microsphere consisting of a non-magnetic core coated with a layer of magnetic nanograins. Namely, the dynamic magnetic ...

Optical quasi-solitons by Lie symmetry analysis
Abstract This paper studies optical quasi-solitons by the aid of Lie group analysis. Nine types of nonlinearities are considered here. They are Kerr law, power law, parabolic law, dual-power law, polynomial law, triple-power law, saturable law,...

Electromagnetic form factors of octet baryons in QCD
Abstract The electromagnetic form factors of octet baryons are estimated within light cone QCD sum rules method, using the most general form of the interpolating current for baryons. A comparison of our predictions on the magnetic dipole and...
