Higgs inflation in a radiative seesaw model
Abstract We investigate a simple model to explain inflation, neutrino masses and dark matter simultaneously. This is based on the so-called radiative seesaw model proposed by E. Ma in order to explain neutrino masses and dark matter by introducing a ...

A varied shaping time noise analysis of Al0.8Ga0.2As and GaAs soft X-ray photodiodes coupled to a low-noise charge sensitive preamplifier
Abstract The noise sources affecting Al0.8Ga0.2As and GaAs spectroscopic X-ray photon counting p+–i–n+ photodiodes connected to a custom low-noise charge sensitive preamplifier are quantified by analysing the system's response to pulses from a...

Generalized parton distributions of the photon
Abstract We present a first calculation of the generalized parton distributions of the photon (both polarized and unpolarized) using overlaps of light-front wave functions at leading order in α and zeroth order in ...

A model for space and time-like proton (neutron) form factors
Abstract A model is suggested to interpret nucleon electromagnetic form factors both in space and time-like regions and to describe the existing data. It implies quarks to be colorless in the region of high intensity chromo-electromagnetic gluon...

Hadron–hadron interactions from imaginary-time Nambu–Bethe–Salpeter wave function on the lattice
Abstract Imaginary-time Nambu–Bethe–Salpeter (NBS) wave function is introduced to extend our previous approach for hadron–hadron interactions on the lattice. Scattering states of hadrons with different energies encoded in the NBS wave function are...

The heterotic string yields natural supersymmetry
Abstract The most promising MSSM candidates of the heterotic string reveal some distinctive properties. These include gauge-top unification, a specific solution to the μ-problem and mirage pattern for the gaugino masses. The location of the top- and ...

Monte Carlo Simulation of Ultrafast Carrier Transport: Scalability Study
Abstract In this work we consider Monte Carlo methods and algorithms for solving quantum-kinetic integral equations which describe the electron transport in semiconductors. Here we study the scalability of the presented algorithms using HPC...

Strongly separated pairs of core electrons in computed ground states of small molecules
Abstract We have performed full configuration interaction computations of the ground states of the molecules Be, BeH2, Li, LiH, B, and BH and verified that the core electrons constitute “separated electron pairs.” These separated pairs of core...

A Quantum Representation for Involution Groups
Abstract We answer a question posed by Martin et al. at MFPS XXVI in the affirmative: the free affine monoid over a finite involution group has a quantum representation, in addition to the classical representation already shown to exist in [Martin,...

Centrality dependence of the pseudorapidity density distribution for charged particles in Pb–Pb collisions at
Abstract We present the first wide-range measurement of the charged-particle pseudorapidity density distribution, for different centralities (the 0–5%, 5–10%, 10–20%, and 20–30% most central events) in Pb–Pb collisions at ...

Artificial gravity field
Abstract Using computer algebra to run Einstein’s equations “backward”, from field to source rather than from source to field, we design an artificial gravity field for a space station or spaceship. Everywhere inside astronauts experience normal...

Phenomenology of the interplay between IR-improved DGLAP-CS theory and NLO ME matched parton shower MC precision
Abstract We present the current status of the application of our approach of exact amplitude-based resummation in quantum field theory to precision QCD calculations, by realistic MC event generator methods, as needed for precision LHC physics. In...

Neutrino properties from Yukawa structure
Abstract We discuss the implications for lepton mixing and CP violation of structure in the lepton mass matrices, for the case that neutrino masses are generated by the see-saw mechanism with an hierarchical structure for the Majorana masses. For...

PCT theorem in field theory on non-commutative space
Abstract The PCT theorem is shown to be valid in quantum field theory formulated on non-commutative space–time by exploiting the properties of the Wightman functions defined in such a set up.
