We consider the Higgs boson production in the gluon-fusion channel to nextto-next-to-leading order within the Minimal Supersymmetric Standard Model. In particular, we present analytical results for the matching coefficient of the effective theory and study its influence on the total production cross section in the limit where the masses of all MSSM particles coincide. For supersymmetric masses ...

In this work, we analyze the deformation of surface waves in shallow flows conditions, propagating in a channel of slowly varying cross-section. Based on a singular perturbation technique, the main purpose is to predict the motion of waves by using a dimensionless formulation of the governing equations, considering that the longitudinal variation of the transversal section obey a power-law dist...

In this paper, the cooling performance of water-cooled heat sinks for heat dissipation from electronic components is investigated numerically. Computational Fluid Dynamics (CFD) simulations are carried out to study the rectangular and circular cross-sectional shaped heat sinks. The sectional geometry of channels affects the flow and heat transfer characteristics of minichannel heat sinks. T...

We present the complete two-loop electroweak corrections to gg → H, the main partonic channel for the production of the Higgs boson at hadron colliders. The evaluation is based on a numerical approach and the result covers all kinematical regions, including WW and ZZ thresholds, by introducing complex masses for the W and the Z bosons. Furthermore the relation between physical observables measu...

We use the Paris nucleon-antinucleon optical potential for explanation of experimental data in the process e + e − → p¯ p near threshold. It is shown that the cross section and the electromagnetic form factors are very sensitive to the parameters of the potential. It turns out that final-state interaction due to slightly modified absorptive part of the potential allows us to reproduce available...

In scenarios with the fundamental unification scale at the TeV one expects string excitations of the standard model fields at accessible energies. We study the neutrino-nucleon cross section in these models. We show that duality of the scattering amplitude forces the existence of a tower of massive leptoquarks that mediate the process in the s channel. Using the narrow-width approximation we fi...

We investigate the observability of the lightest Higgs boson in the gluon–fusion channel at the CERN Large Hadron Collider (LHC) in the minimal supersymmetric Standard Model with explicit CP–violating mixing among three neutral Higgs bosons. The lightest Higgs boson with its mass less than 130 GeV can be detected at the LHC via its gluon–fusion production followed by the decay into two photons....

A dual model with a nonlinear proton Regge trajectory in the missing mass (M2X) channel is constructed. background based on direct-channel exotic trajectory, developed and applied earlier for inclusive electron-proton cross section description nucleon resonance region, used. The parameters of are determined from extrapolations to experiments. Predictions low-mass (2 < M2X 8 GeV2) diffraction...
