Renormalisability of gauge invariant extensions of the squared gauge potential
Abstract We show that gauge invariant extensions of the local functional O= 1 2 ∫d4xA2 have long range non-localities which...

Entropy of an extremal regular black hole
Abstract We introduce a magnetically charged extremal regular black hole in the coupled system of Einstein gravity and nonlinear electrodynamics. Its near horizon geometry is given by AdS ...

Form factor decomposition of generalized parton distributions at leading twist
Abstract We extend the counting of generalized form factors presented in [Phys. Rev. D 63 (2001) 076005] by Ji and Lebed to the axial vector and the tensor operator at twist-2 level. Following this, a parameterization of all higher moments in x of...

Exploring leptonic CP violation by reactor and neutrino superbeam experiments
Abstract We point out the possibility that reactor measurement of θ 13, when combined with high-statistics ν e appearance accelerator experiments, can detect...

New physics effects in Higgs decay to tau leptons
Abstract We study the possible effects of TeV scale new physics (NP) on the rate for Higgs boson decays to charged leptons, focusing on the τ + ...

Testing the kt-factorization approach with P-wave quarkonia production
Abstract A new qualitative test of the k t -factorization approach is proposed. We analyse the production of P-wave quarkonium states with different spins χ 0, χ ...

Higgs boson masses in the MSSM with general soft breaking
Abstract The operators that break supersymmetry can be holomorphic or non-holomorphic in structure. The latter do not pose any problem for gauge hierarchy and are soft provided that the particle spectrum does not contain any gauge singlets. In...

Self-duality and supersymmetry
Abstract We observe that the Hamiltonian H = D̸ 2 , where ...

Remarks on global anomalies in RCFT orientifolds
Abstract We check the list of supersymmetric standard model orientifold spectra of Dijkstra, Huiszoon and Schellekens for the presence of global anomalies, using probe branes. Absence of global anomalies is found to impose strong constraints, but in ...

Direct CP violation in B∓→π∓ω, π∓ρ0, π0ρ∓, and in B0(B0)→π∓ρ± with an enhanced branching ratio for π0ρ0
Abstract We present a novel dynamics for generating sizable CP-violating asymmetries in the decays of charged B ∓→π ∓ ω,π ∓ ρ ...

Meta-stable supersymmetry breaking vacua on intersecting branes
Abstract We identify configurations of intersecting branes that correspond to the meta-stable supersymmetry breaking vacua in the four-dimensional N = 1 ...

Elasticity of nuclear medium as a principal macrodynamical promoter of electric pygmy dipole resonance
Abstract Motivated by arguments of the nuclear core-layer model formulated in [S.I. Bastrukov, J.A. Maruhn, Z. Phys. A 335 (1990) 139], the macroscopic excitation mechanism of the electric pygmy dipole resonance (PDR) is considered as owing its...

Hadron formation and attenuation in deep inelastic lepton scattering off nuclei
Abstract We investigate hadron formation in deep inelastic lepton scattering on N, Kr and Xe nuclei in the kinematic regime of the HERMES experiment. The elementary electron–nucleon interaction is described within the event generator PYTHIA while a...

New constraints for CP-violating forces between nucleons in the range 1 micrometer to 1 centimeter
Abstract The range of nucleon interaction 10−4 cm–1 cm is interesting because it corresponds to the mass range of an intermediate particle within the so-called “axion window” that is not closed yet by experiment. Depolarization of ultracold neutrons ...

Quantum cosmology of classically constrained gravity
Abstract In [G. Gabadadze, Y. Shang, hep-th/0506040] we discussed a classically constrained model of gravity. This theory contains known solutions of General Relativity (GR), and admits solutions that are absent in GR. Here we study cosmological...

On cutoff effects in lattice QCD from short to long distances
Abstract We discuss kinematical enhancements of cutoff effects at short and intermediate distances. Starting from a pedagogical example with periodic boundary conditions, we switch to the case of the Schrödinger functional, where the theoretical...

Non-forward BFKL pomeron at next-to-leading order
Abstract The kernel of the BFKL equation for non-zero momentum transfer is found at next-to-leading order. It is presented in various forms depending on the regularization of the infrared singularities in “virtual” and “real” parts of the kernel....
