Convective transport in a porous medium layer saturated with a Maxwell nanofluid
Abstract A linear and weakly non-linear stability analys is has been carried out to study the onset of convection in a horizontal layer of a porous medium saturated with a Maxwell nanofluid. To simulate the momentum equation in porous media, a...

An ANN-based approach to predict blast-induced ground vibration of Gol-E-Gohar iron ore mine, Iran
Abstract Blast-induced ground vibration is one of the inevitable outcomes of blasting in mining projects and may cause substantial damage to rock mass as well as nearby structures and human beings. In this paper, an attempt has been made to present...

Rare B→ℓ+ℓ−γ decay and new physics effects
Abstract Using the most general, model independent form of the effective Hamiltonian rare decays B→ℓ+ℓ− γ (ℓ=μ,τ) are studied. The sensitivity of the photon energy distribution and branching ratio to the new Wilson coefficients...

Correction terms to Newton law due to induced gravity in AdS background
Abstract We calculate small correction terms to gravitational potential on Randall–Sundrum brane with an induced Einstein term. The behaviors of the correction terms depend on the magnitudes of AdS radius k −1 and a...

Exact Witten index in D=2 supersymmetric Yang–Mills quantum mechanics
Abstract A new, recursive method of calculating matrix elements of polynomial hamiltonians is proposed. It is particularly suitable for the recent algebraic studies of the supersymmetric Yang–Mills quantum mechanics in any dimensions. For the D=2...

RG generated fermion mass
Abstract Chiral symmetry breaking in a purely fermionic theory is investigated by the help of the renormalization group method. It is shown that the RG equation for the running mass m k ...

Physics of strongly coupled N=1 supersymmetric SO(Nc) gauge theories

A quantization of (2+1)-gravity related to high-energy Yang–Mills theory
Abstract We point out that canonical quantization of the two-body problem in (2+1)-gravity is related to the high-energy equation in Yang–Mills theory by a proper ordering of the relevant operators. This feature arises from expanding the Hamiltonian ...

The anomalous dimension of the composite operator A2 in the Landau gauge
Abstract The local composite operator A 2 is analysed in pure Yang–Mills theory in the Landau gauge within the algebraic renormalization. It is proven that the anomalous dimension of A 2 is not an...

Scale dependence of hadronic wave functions and parton densities
Abstract We study how the components of hadronic wave functions in light-cone quantization depend on the ultraviolet cut-off by relating them in a systematic way to the matrix elements of a class of quark–gluon operators between the QCD vacuum and...

On nonperturbative solutions of superstring field theory
Abstract Nonperturbative solutions to the nonlinear field equations in the NS sector of cubic as well as nonpolynomial superstring field theory can be obtained from a linear equation which includes a “spectral” parameter λ and a coboundary operator...

The g factor of the proton
Abstract We consider higher order corrections to the g factor of a bound proton in hydrogen atom and their consequences for a magnetic moment of free and bound proton and deuteron as well as some other objects.

A determination of Aμ2 and the non-perturbative vacuum energy of Yang–Mills theory in the Landau gauge
Abstract We discuss the 2-point-particle-irreducible (2PPI) expansion, which sums bubble graphs to all orders, in the context of SU(N) Yang–Mills theory in the Landau gauge. Using the method we investigate the possible existence of a gluon...

Transition rates in charged boson nebulae
Abstract Using the first-order approximating solutions to the Einstein–Maxwell–Klein–Gordon system of equations for a complex scalar field minimally coupled to a spherically symmetric spacetime, we study the feedback of gravity and electric field on ...

On the Landau–Ginzburg theory of MAG projected SU(2) lattice gauge theory
Abstract Maximal Abelian gauge fixing and subsequent Abelian projection of SU(2) lattice gauge theory defines closed trajectories of magnetic monopoles. These trajectories can be interpreted in terms of an effective scalar field theory of the MAG...
