mu+md from isovector pseudoscalar sum rules
Abstract We revisit the isovector pseudoscalar sum rule determination of m u +m d , using families of finite energy ...

Gravitational deflection of light and helicity asymmetry
Abstract The helicity modification of light polarization which is induced by the gravitational deflection from a classical heavy rotating body, like a star or a planet, is considered. The expression of the helicity asymmetry is derived; this...

Boundary states and symplectic fermions
Abstract We investigate the set of boundary states in the symplectic fermion description of the logarithmic conformal field theory with central charge c=−2. We show that the thus constructed states correspond exactly to those derived under the...

Spin-triplet final-state dominance in the pp→pnπ+ reaction at 492 MeV
Abstract The near-forward cross section for the pp→pnπ + reaction has been measured at 492 MeV by using the large acceptance ANKE magnetic spectrometer placed at an internal target position of the storage ring COSY-Jülich....

Charm quark mass
Abstract We report on the result for the charm quark mass as obtained from our lattice QCD computation in the quenched approximation. Our result is mc MS ...

Charm meson production from meson–nucleon scattering
Abstract Using an effective hadronic Lagrangian with physical hadron masses and coupling constants determined either empirically or from SU(4) flavor symmetry, we study the production cross sections of charm mesons from pion and rho meson...

Indications of partial chiral symmetry restoration from pionic atoms
Abstract Extensive data on strong interaction effects in pionic atoms are analyzed with a density-dependent isovector scattering amplitude suggested recently by Weise to result from a density dependence of the pion decay constant. Most of the...

Production of ultra-energetic cosmic rays through the decay of super-heavy X particles
Abstract We present a new and complete numerical analysis of the decay of super-heavy X particles, assumed to be the origin of cosmic rays with energy beyond the GZK cut-off. The decay of X initiates a “parton shower”, where we include all degrees...

Suppressing Hawking radiation by quantum Zeno effect
Abstract We present evidence that quantum Zeno effect, otherwise working only for microscopic systems, may also work for large black holes (BH's). The expectation that a BH geometry should behave classically at time intervals larger than the Planck...

Closed string amplitudes as single-valued open string amplitudes
Abstract We show that the single trace heterotic N-point tree-level gauge amplitude A ...

Constraints on RG flow for four dimensional quantum field theories
Abstract The response of four dimensional quantum field theories to a Weyl rescaling of the metric in the presence of local couplings and which involve a, the coefficient of the Euler density in the energy momentum tensor trace on curved space, is...

Effect of particle fluctuation on isoscaling and isobaric yield ratio of nuclear multifragmentation
Abstract Isoscaling and isobaric yield ratio parameters are compared from canonical and grand canonical ensembles when applied to multifragmentation of finite nuclei. Source dependence of isoscaling parameters and source and isospin dependence of...

Generalization of a summation formula due to Fox
Abstract By employing classical Gauss’s second summation theorem for the series 2 F 1, Fox established the following interesting and useful summation formula for the series ...

Quarkonium production in the LHC era: A polarized perspective
Abstract Polarization measurements are usually considered as the most difficult challenge for the QCD description of quarkonium production. In fact, global data fits for the determination of the non-perturbative parameters of bound-state formation...

Charged-lepton mixing and lepton flavor violation
Abstract We present a model for calculating charged-lepton mixing matrices. These matrices are an essential ingredient for predicting lepton flavor-violating rates in the lepton number nonuniversal models recently proposed to explain anomalies in...
