Production of heavy vector particles in interactions of leptons with the massless gauge bosons
Abstract The cross section for vector leptoquark production in electron–gluon collisions is calculated analytically using the Lagrangian with the minimal couplings between the leptoquarks and the gauge fields of the standard model. It is found that...

Comments on Yang–Mills thermodynamics: The Hagedorn spectrum and the gluon gas pictures for a generic gauge algebra
Abstract We discuss the dependence of pure Yang–Mills equation of state on the choice of gauge algebra. In the confined phase, we generalize to an arbitrary simple gauge algebra Meyerʼs proposal of modeling the Yang–Mills matter by an ideal glueball ...

β-Delayed proton-decay study of 20Mg and its implications for the breakout reaction in X-ray bursts
Abstract Under astrophysical conditions of high temperature and density, such as for example found in X-ray bursts, breakout can occur from the hot CNO cycles into the rapid proton capture process. A key breakout route is via the sequence ...

Confronting dark energy models mimicking ΛCDM epoch with observational constraints: Future cosmological perturbations decay or future Rip?
Abstract We confront dark energy models which are currently similar to ΛCDM theory with observational data which include the SNe data, matter density perturbations and baryon acoustic oscillations data. DE cosmology under consideration may evolve to ...

A concise quantum efficiency measurement system for gaseous photomultipliers
Abstract We have been developing gaseous photomultiplier tubes (PMTs) with a bialkali photocathode combined with micropattern gas detectors (MPGDs). The sensitivity of a PMT is described in terms of its quantum efficiency (QE). The QE is very...

Neutron matter instabilities induced by strong magnetic fields
Abstract We study some properties of spin-polarized neutron matter in the presence of a strong magnetic field at finite temperature. Using the Skyrme model together with the Hartree–Fock approximation we obtain an energy density functional that is...

Impact of rotation-driven particle repopulation on the thermal evolution of pulsars
Abstract Driven by the loss of energy, isolated rotating neutron stars (pulsars) are gradually slowing down to lower frequencies, which increases the tremendous compression of the matter inside of them. This increase in compression changes both the...

Applications of an identity of Andrews
Abstract In this paper, we give a bilateral form of an identity of Andrews, which is a generalization of the 1 ψ 1 summation formula of Ramanujan. Using Andrews’ identity, we deduce some new identities...

Application of the Silicon Photomultipliers for Detectors in the GlueX Experiment
Abstract The GlueX detector in Hall D at Jefferson Lab [1]is instrumented with about 5000 Silicon Photomultipliers (SiPM) manufactured by Hamamatsu Corporation [2]. These photo sensors have properties similar to conventional photomultipliers but can ...

ATLAS silicon microstrip tracker operation and performance
Abstract The Semi-Conductor Tracker is a silicon microstrip detector at the heart of the ATLAS experiment at the CERN Large Hadron Collider. Together with the rest of the ATLAS Inner Detector it provides vital precision tracking information of...

A New Type of Radical-Pair-Based Model for Magnetoreception
Abstract Certain migratory birds can sense the Earth's magnetic field. The nature of this process is not yet properly understood. Here we offer a simple explanation according to which birds literally see the local magnetic field through the impact...

Hunting radions at linear colliders
Abstract We investigate the possibility to disentangle the radions in the Randall–Sundrum scenario from Higgs boson at the next generation high energy e + e − linear colliders. Due to...

Majorana phase in minimal S3 invariant extension of the standard model
Abstract The leptonic sector in a recently proposed minimal extension of the standard model, in which the permutation symmetry S 3 is assumed to be an exact flavor symmetry at the weak scale, is revisited. We find that S ...

Global geometry of the 2+1 rotating black hole
Abstract The generic rotating BTZ black hole, obtained by identifications in AdS 3 space through a discrete subgroup of its isometry group, is investigated within a Lie theoretical context. This space is found to admit a...

Dead-Time Free Measurement of Dipole–Dipole Interactions between Electron Spins
Abstract A four-pulse version of the pulse double electron–electron resonance (DEER) experiment is presented, which is designed for the determination of interradical distances on a nanoscopic lengthscale. With the new pulse sequence...
