Scalar supersymmetry
Abstract We describe a new realization of supersymmetry, called scalar supersymmetry, acting in spaces of differential forms (bi-spinors), where transformation parameters are Lorentz scalars instead of spinors. The realization is related but is not...

Higgs inflation at the critical point
Abstract Higgs inflation can occur if the Standard Model (SM) is a self-consistent effective field theory up to inflationary scale. This leads to an upper bound on the top Yukawa coupling, ...

Effect of double stratification on MHD free convection in a micropolar fluid
Abstract This paper analyzes the flow and heat and mass transfer characteristics of the free convection on a vertical plate with variable wall temperature and concentration in a doubly stratified micropolar fluid. A uniform magnetic field is applied ...

The role of Glauber exchange in soft collinear effective theory and the Balitsky–Fadin–Kuraev–Lipatov Equation
Abstract In soft collinear effective theory (SCET) the interaction between high energy quarks moving in opposite directions involving momentum transfer much smaller than the center-of-mass energy is described by the Glauber interaction operator...

Fourier Monte Carlo Implementation Guide
Abstract The Fourier Monte Carlo algorithm represents a powerful tool to study criticality in lattice spins systems. In par- ticular, the algorithm constitutes an interesting alternative to other simulation approaches for models with microscopic or...

An exact solution for R2,eff in CPMG experiments in the case of two site chemical exchange
Abstract The Carr–Purcell–Meiboom–Gill (CPMG) experiment is widely used to quantitatively analyse the effects of chemical exchange on NMR spectra. In a CPMG experiment, the effective transverse relaxation rate, R 2, ...

Bound Beta-decay of the Free Neutron: BoB
Abstract For many years neutron decay has been investigated as a possible pathway to the exploration of new physics. One such example is the bound beta-decay (BoB) of the neutron into a hydrogen atom and an anti-neutrino. This two-body decay mode...

Checking flavour models at neutrino facilities
Abstract In the recent years, the industry of model building has been the subject of the intense activity, especially after the measurement of a relatively large values of the reactor angle. Special attention has been devoted to the use of...

Quantum M2→2Λ/3 discontinuity for massive gravity with a Λ term
Abstract In a previous paper we showed that the absence of the van Dam–Veltman–Zakharov discontinuity as M 2→0 for massive spin 2 with a Λ term is an artifact of the tree approximation, and that the discontinuity reappears at...

Scalar σ meson effects in ρ and ω decays into π0π0γ
Abstract The complementarity between chiral perturbation theory and the linear sigma model in the scalar channel is exploited to study π 0 π 0 production in ρ and ω radiative decays,...

CP violation, neutrino mixing and the baryon asymmetry
Abstract We study neutrino masses and mixings based on the simplest SO(10) mass relations and the seesaw mechanism. We find that the requirement of large neutrino mixings determines the relative magnitude of the heavy Majorana neutrino masses in...

Coupling effects in the elastic scattering of the exotic nucleus 6He on protons
Abstract Cross sections for the elastic scattering of 6He radioactive nuclear beam on proton targets have been measured at 38.3 MeV/nucleon. With a view to test the ability of general optical potentials to reproduce the data for scattering of...

Some aspects of brane inflation
Abstract The inflaton potential in four-dimensional theory is rather arbitrary, and fine-tuning is required generically. By contrast, inflation in the brane world scenario has the interesting feature that the inflaton potential is motivated from...

Anomalous C-violating three photon decay of the neutral pion in noncommutative quantum electrodynamics
Abstract We show that a simple and reasonable generalization of the anomalous interaction between the neutral pion and two photons can induce the C-violating three photon decay of the neutral pion in noncommutative quantum electrodynamics. We find...

GUT breaking on the lattice
Abstract We construct a supersymmetric grand unified model in the framework of a latticized extra dimension. The SU(5) symmetries on the lattice are broken by the vacuum expectation values of the link fields connecting adjacent SU(5) sites, leaving...

Higher order corrections to primordial spectra from cosmological inflation
Abstract We calculate power spectra of cosmological perturbations at high accuracy for two classes of inflation models. We classify the models according to the behaviour of the Hubble distance during inflation. Our approximation works if the Hubble...

Is the Coulomb sum rule violated in nuclei?
Abstract Guided by the experimental confirmation of the validity of the Effective Momentum Approximation (EMA) in quasi-elastic scattering off nuclei, we have re-examined the extraction of the longitudinal and transverse response functions in...
