Inclusive resonance production in single-vee events in [pi]- nucleon interactions at 200 GeV
We present results from Fermilab MPS experiment E580 on the reactions π⁻N->V°X where V° is K°<sub>S</sub>, A or A̅ and X are charged particles. Transverse and longitudinal momentum distributions for the V° and for K*<sup>±</sup>(892), Σ<sup>±</sup>(1385), Ξ⁻(1321) and Ξ⁺(1321) are presented. A …

Studies of Two-Nucleon Interactions and Few-Body Electromagnetic Structure in Chiral Effective Field Theory
<p>A coordinate-space nucleon-nucleon potential is constructed in chiral effective field theory (χEFT) retaining pions, nucleons and Δ-isobars as explicit degrees of freedom. The calculation of the potential is carried out by including one-and two-pion-exchange contributions up to …

Green's function Monte Carlo calculations of few-nucleon systems
Recently, a realistic nucleon-nucleon potential has been developed with the goal of accurately reproducing isospin symmetry breaking effects in the nuclear interaction. We briefly discuss the motivation for this potential, called Argonne $v\sb{18},$ as well as the Urbana models of three-nucleon …

Dynamic Pion Studies in Nuclear Matter
… which allows the extension of current realistic Nucleon-Nucleon interactions to include pionic degrees of freedom. A prescription for transforming any static pion model to one containing explicit energy dependence is provided. We show that adding energy dependence to the pionic component of the …

Applications of Low Temperature Bolometers to Reactor Neutrinos and Neutrinoless Double Beta Decay
… a neutrino magnetic moment and non-standard interactions between neutrinos and quarks. In particular, combining multiple detector materials and measuring CEvNS at a reactor places leading bounds on beyond the Standard Model neutrino-nucleon interactions. Limiting such interactions is crucial …

Quantum Monte Carlo Calucations Of Three And Six-Quark States
… due to flux-tube confinement, and two-body interactions arising from one-gluon and one-pion exchange. It is strongly dependent on the spin and isospin of the quarks. We solve for single baryon S and P-wave spectra by solving the Schrodinger equation variationally for the ground state of …

Probing New Physics Through Third Generation Leptons
… New physics contributions to the tau-neutrino nucleon scattering were considered. Charged Higgs and W' effects to the deep inelastic scattering ντ ( [special character omitted]τ) + N → τ− (τ+) + X in the neutrino-nucleon interactions has been studied. The neutrino detection process at neutrino …

Variational Theory of Hot Dense Matter
… The Hamiltonian contains modern realistic two nucleon and three nucleon interactions along with relativistic boost corrections. Expectation values of various operators, including the Hamiltonian, are calculated using cluster expansion and chain summation techniques. The pair correlation …

Neutrino emission and pion condensation in dense matter
… In the simplest of these models (p-wave pion-nucleon interaction a1one) it is found that matter is unstable to the formation of a condensed pion mode. This model is made more realistic by including other forces: s-wave pion-nucleon interactions pi-pi interactions, and phenomenological form …

Advances in ab initio approaches to nuclear structure, reaction and nucleonic dynamics
… with the Okubo-Lee-Suzuki formalism for two-nucleon systems. Working within a harmonic oscillator basis, first without and then with a confining harmonic oscillator trap, we demonstrate the effects of renormalization on observables calculated for truncated basis spaces. We illustrate the …

Heavy-flavour production at forward rapidity as a function of charged-particle multiplicity with ALICE at the LHC
… is a significant contribution of Multiple Parton Interactions (MPI), i.e. several hard partonic interactions occurring in a single collision between nucleons. Therefore, the measurement of heavy-flavour hadrons as a function of charged-particle multiplicity gives insight into the mechanisms …

Triton Wave Functions Using Realistic Potentials.
Because the study of three-nucleon systems may provide information pertaining to the interaction between nucleons, much theoretical effort during the past forty years has been devoted to such systems. Provided that a means is found to predict accurately the eigenvalues and eigenfunctions which …
