Isocurvature fluctuations in tracker quintessence models
Abstract We consider effects of the isocurvature perturbation in the framework of the tracker-type quintessence models. During the inflation, fluctuations in the amplitude of the quintessence field are generated, which provide isocurvature component ...

On three-body B0→D∗−D(∗)0K+ decays and couplings of heavy mesons to light pseudoscalar mesons
Abstract We analyze the decay modes B0→D∗−D0K+ and B0→D∗−D∗0K+ and, using the available experimental data, we find bounds for the constants g and h describing the strong coupling of heavy mesons to light...

Anisotropic non-gaussianity with noncommutative spacetime
Abstract We study single field inflation in noncommutative spacetime and compute two-point and three-point correlation functions for the curvature perturbation. We find that both power spectrum and bispectrum for comoving curvature perturbation are...

A 2.5m long liquid hydrogen target for COMPASS
Abstract A 2.5m long liquid hydrogen target has been developed for the COMPASS experiment at CERN to investigate the nucleon spin structure via the Deeply Virtual Compton Scattering (DVCS) process. To recognize exclusive DVCS events, produced...

Electromagnetic two-point functions and Casimir densities for a conducting plate in de Sitter spacetime
Abstract We evaluate the two-point function for the electromagnetic field tensor in ( D + 1 ) -dimensional...

Studies of azimuthal modulations in two hadron fragmentation of a transversely polarised quark
Abstract We study the azimuthal modulations of dihadron fragmentation functions (DiFFs) of a transversely polarised quark using an NJL-jet based model that incorporates the Collins effect for single hadron emission. The DiFFs are extracted as Monte...

New exclusion limits on dark gauge forces from proton Bremsstrahlung in beam-dump data
Abstract We re-analyze published proton beam dump data taken at the U70 accelerator at IHEP Serpukhov with the ν-calorimeter I experiment in 1989 to set mass-coupling limits for dark gauge forces. The corresponding data have been used for axion and...

On regularizing the infrared singularities in QCD NLO splitting functions with the new Principal Value prescription
Abstract We propose a modified use of the Principal Value prescription for regularizing the infrared singularities in the light-cone axial gauge by applying it to all singularities in the light-cone plus component of integration momentum. The...
