Dispersion relations and soft pion theorems for K→ππ
Abstract We propose a new method to obtain the K→ππ amplitude from K→π which allows one to fully account for the effects of final state interactions. The method is based on a set of dispersion relations for the K→ππ amplitude in which the weak...

Study of system-size effects in multi-fragmentation using quantum molecular dynamics model
Abstract We report, for the first time, the dependence of the multiplicity of different fragments on the system size employing a quantum molecular dynamics model. This dependence is extracted from the simulations of symmetric collisions of Ca+Ca,...

In-flight Conductivity and Temperature Measurements of Hypervelocity Projectiles
Abstract The conductivity and temperature of hypervelocity projectiles were studied using a novel magnetic diffusion analysis technique and five color radiometry. A copper shaped charge jet was fired through an electromagnetic coil to saturate the...

Noncommutative multi-instantons on R2n×S2
Abstract Generalizing self-duality on R 2×S2 to higher dimensions, we consider the Donaldson–Uhlenbeck–Yau equations on R 2n×S2 ...

Fine structure constant variation from a late phase transition
Abstract Recent experimental data indicates that the fine structure constant α may be varying on cosmological time scales. We consider the possibility that such a variation could be induced by a second order phase transition which occurs at late...

Subleading shape functions in B→Xuℓν̄ and the determination of |Vub|
Abstract We calculate the subleading twist contributions to the endpoint of the inclusive lepton energy spectrum in B→Xuℓ ν ̄ . We show that the same ...

Higgs boson production via double Pomeron exchange at the LHC
Abstract We study Higgs boson production via double Pomeron exchange allowing for the presence of Pomeron remnants. We estimate the number of events produced at the LHC collider, as a function of the Higgs boson mass and its decay channel. The model ...

Quarks and leptons between branes and bulk
Abstract We study a supersymmetric SO(10) gauge theory in six dimensions compactified on an orbifold. Three sequential quark–lepton families are localized at the three fixpoints where SO(10) is broken to its three GUT subgroups. Split bulk...

The dipole picture and saturation in soft processes
Abstract We attempt to describe soft hadron interactions in the framework of saturation models, one based upon the Balitsky–Kovchegov non-linear equation and another one due to Golec-Biernat and Wüsthoff. For pp, Kp, and πp scattering the relevant...

Supersymmetric dark matter in light of WMAP
Abstract We re-examine the parameter space of the constrained minimal supersymmetric extension of the Standard Model (CMSSM), taking account of the restricted range of Ω CDM h2 ...

Four-zero texture of Hermitian quark mass matrices and current experimental tests
Abstract We show that the four-zero texture of Hermitian quark mass matrices can survive current experimental tests: it is able to yield sufficiently large predictions for the flavor mixing parameter |V ...

Complete N=4 structure of low-energy effective action in N=4 super-Yang–Mills theories
Abstract Using the N=2 superfield approach, we construct full N=4 supersymmetric low-energy effective actions for N=4 SYM models, with both N=2 gauge ...

More remarks on suppression of large black hole production in particle collisions
Abstract The problem of evaluating the cross section of production of large black holes in particle collisions at trans-Planckian energies is revisited. It is argued that the geometric cross section claimed in the literature would in fact lead to an ...

Upper bound on the radii of black-hole photonspheres
Abstract One of the most remarkable predictions of the general theory of relativity is the existence of black-hole “photonspheres”, compact null hypersurfaces on which massless particles can orbit the central black hole. We prove that every...

Heavy Flavour Cross Section Measurements with the ATLAS Detector
Abstract ATLAS measurements of heavy flavour production cross sections are presented from proton-proton collisions at the LHC at a centre-of-mass energy of 7 TeV. These make use of b-hadron decays to ...

Regular black hole metrics and the weak energy condition
Abstract In this work we construct a family of spherically symmetric, static, charged regular black hole metrics in the context of Einstein-nonlinear electrodynamics theory. The construction of the charged regular black hole metrics is based on...
