Kinetic neoclassical calculations of impurity radiation profiles
Abstract Modifications of the drift-kinetic transport code XGC0 to include the transport, ionization, and recombination of individual charge states, as well as the associated radiation, are described. The code is first applied to a simulation of an...

Peristalsis of nonconstant viscosity Jeffrey fluid with nanoparticles
Abstract Mixed convective peristaltic activity of variable viscosity nanofluids is addressed. Unlike the conventional consideration of constant viscosity; the viscosity is taken as temperature dependent. Constitutive relations for linear...

Comparing the Rξ gauge and the unitary gauge for the standard model: An example
Abstract For gauge theory, the matrix element for any physical process is independent of the gauge used. However, since this is a formal statement, it does not guarantee this gauge independence in every case. An example is given here where, for a...

Magnetic Measurements of Superconducting Insertion Devices by Stretched Wire with Direct Current
Abstract The main characteristics of multipole insertion devices (ID) are the first and second field integrals along an orbit trajectory in an accelerator. Such integrals of permanent magnets or traditional electromagnets insertion devices can be...

The wave equation: From eikonal to anti-eikonal approximation
Abstract When the refractive index changes very slowly compared to the wave-length we may use the eikonal approximation to the wave equation. In the opposite case, when the refractive index highly variates over the distance of one wave-length, we...

λ-Deformations of left–right asymmetric CFTs
Abstract We compute the all-loop anomalous dimensions of current and primary field operators in deformed current algebra theories based on a general semi-simple group, but with different (large) levels for the left and right sectors. These theories, ...

Lepton number violation by heavy Majorana neutrino in B decays
Abstract Heavy Majorana neutrinos are predicted in addition to ordinary active neutrinos in the models with the seesaw mechanism. We investigate the lepton number violation (LNV) in B decays induced by such a heavy neutrino N with GeV-scale mass....

Assessment of the Implementation of a Neutron Measurement System During the Commissioning of the Jordan Research and Training Reactor
Abstract The Jordan Research and Training Reactor (JRTR) is the first research reactor in Jordan, the commissioning of which is ongoing. The reactor is a 5-MWth, open-pool type, light-water-moderated, and cooled reactor with a heavy water reflector...

The width of the Δ-resonance at two loop order in baryon chiral perturbation theory
Abstract We calculate the width of the delta resonance at leading two-loop order in baryon chiral perturbation theory. This gives a correlation between the leading pion–nucleon–delta and pion–delta couplings, which is relevant for the analysis of...

Gravitational surface Hamiltonian and entropy quantization
Abstract The surface Hamiltonian corresponding to the surface part of a gravitational action has xp structure where p is conjugate momentum of x. Moreover, it leads to TS on the horizon of a black hole. Here T and S are temperature and entropy of...

Topological sigma models on supermanifolds
Abstract This paper concerns constructing topological sigma models governing maps from semirigid super Riemann surfaces to general target supermanifolds. We define both the A model and B model in this general setup by defining suitable BRST...

Exploring high-mass diphoton resonance without new colored states
Abstract A new heavy resonance may be observable at the LHC if it has a significant decay branching fraction into a pair of photons. We entertain this possibility by looking at the modest excess in the diphoton invariant mass spectrum around 750 GeV ...

Horizon thermodynamics in fourth-order gravity
Abstract In the framework of horizon thermodynamics, the field equations of Einstein gravity and some other second-order gravities can be rewritten as the thermodynamic identity: d E ...

Helicity in proton–proton elastic scattering and the spin structure of the pomeron
Abstract We discuss different models for the spin structure of the nonperturbative pomeron: scalar, vector, and rank-2 symmetric tensor. The ratio of single-helicity-flip to helicity-conserving amplitudes in polarised high-energy proton–proton...

Generalized λ-deformations of AdSp×Sp
Abstract We study analytical properties of the generalized λ-deformation, which modifies string theories while preserving integrability, and construct the explicit backgrounds corresponding to ...

On the Bohm criterion in the presence of a magnetic field
Abstract The present paper deals with a particular case involving a magnetic field, namely that of a positive column situated in an axial magnetic field, and it is shown that the Bohm criterion still holds for the normal component of the ion...
