Final state interactions and the extraction of neutron single spin asymmetries from semi-inclusive deep-inelastic scattering by a transversely polarized $^{3}\mathrm{He}$ target

2017-12-12T10:00:00+00:00

Author(s): A. Del Dotto, L. P. Kaptari, E. Pace, G. Salmè, and S. Scopetta

The semi-inclusive deep-inelastic electron scattering off transversely polarized $^{3}\mathrm{He}$, i.e., the process $e+\stackrel{⃗}{^{3}\mathrm{He}}→{e}^{′}+h+X$, with $h$ being a detected fast hadron, is studied beyond the plane-wave impulse approximation. To this end, a distorted spin-dependent ...

Nonradial oscillation modes of compact stars with a crust

2017-12-12T10:00:00+00:00

Author(s): Cesar Vásquez Flores, Zack B. Hall, II, and Prashanth Jaikumar

Oscillation modes of isolated compact stars can, in principle, be a fingerprint of the equation of state (EoS) of dense matter. We study the non-radial high-frequency $l=2$ spheroidal modes of neutron stars and strange quark stars, adopting a two-component model (core and crust) for these two types ...

Global $\mathrm{Λ}$ polarization in heavy-ion collisions from a transport model

2017-11-29T10:00:00+00:00

Author(s): Hui Li, Long-Gang Pang, Qun Wang, and Xiao-Liang Xia

Off-central relativistic heavy ion collisions impart very large orbital angular momenta onto the quark-gluon plasma, creating a strong vortex in the initial hot fluid and appearing eventually, via spin-vorticity coupling, as particle polarization. From the vorticity field given by a multi-phase transport model the authors compute the global polarization of Λ baryons which is in agreement with experimental data. This suggests that the spin of a hadron could provide information on quark-gluon plasma flow.

Author(s): M. H. Sikora et al.

Compton scattering, where the electromagnetic field of a real photon induces radiation multipoles by displacing charges and currents inside the nucleon, is an important probe of both the structure of light nuclei and the nucleon polarizabilities. This paper presents the first extensive and precise measurements of elastic Compton scattering on 4He. These results should allow precision comparisons with new calculations expected from both lattice gauge and effective field theories.

Here we concentrate on the situation of la...

Elastic and inelastic pion-nucleon scattering to fourth order in chiral perturbation theory

Author(s): D. Siemens, V. Bernard, E. Epelbaum, A. M. Gasparyan, H. Krebs, and Ulf-G. Meißner

We extend our previous study of elastic pion-nucleon scattering in the framework of chiral perturbation theory by performing a combined analysis of the reactions $πN→πN$ and $πN→ππN$. The calculation is carried out to fourth order in the chiral expansion using the heavy-baryon approach and the covar...

Bismuth capture of neutrons is the termination point of the $s$-process cycle of nucleosynthesis in stellar environments. A new measurement is reported here for neutron activation of bismuth with an intense quasi-Maxwellian neutron source at $kT∼30\phantom{\rule{0.16em}{0ex}}\mathrm{keV}$. The measu...

Nuclear matter fourth-order symmetry energy in nonrelativistic mean-field models

Author(s): Jie Pu, Zhen Zhang, and Lie-Wen Chen

Background: Nuclear matter fourth-order symmetry energy ${E}_{\text{sym,4}}(ρ)$ may significantly influence the properties of neutron stars such as the core-crust transition density and pressure as well as the proton fraction at high densities. The magnitude of ${E}_{\text{sym,4}}(ρ)$ is, however, l...

Author(s): Nirbhay K. Behera, Sadhana Dash, Bharati Naik, Basanta K. Nandi, and Tanmay Pani

The charged-particle multiplicity distribution and the transverse-energy distribution measured in heavy-ion collisions at top RHIC and LHC energies are described using the two-component model approach based on a convolution of the Monte Carlo Glauber model with the Weibull model for particle product...

Microscopic core-quasiparticle coupling model for spectroscopy of odd-mass nuclei

Author(s): S. Quan, W. P. Liu, Z. P. Li, and M. S. Smith

Background: Predictions of the spectroscopic properties of low-lying states are critical for nuclear structure studies but are problematic for nuclei with an odd nucleon due to the interplay of the unpaired single particle with nuclear collective degrees of freedom.

Neutrinoless double-$β$ decay matrix elements in large shell-model spaces with the generator-coordinate method

Author(s): C. F. Jiao, J. Engel, and J. D. Holt

We use the generator-coordinate method (GCM) with realistic shell-model interactions to closely approximate full shell-model calculations of the matrix elements for the neutrinoless double-$β$ decay of $^{48}\mathrm{Ca}$, $^{76}\mathrm{Ge}$, and $^{82}\mathrm{Se}$. We work in one major shell for the...

Partial correlation analysis method in ultrarelativistic heavy-ion collisions

2017-11-13T10:00:00+00:00

Author(s): Adam Olszewski and Wojciech Broniowski

We argue that statistical data analysis of two-particle longitudinal correlations in ultrarelativistic heavy-ion collisions may be efficiently carried out with the technique of partial covariance. In this method, the spurious event-by-event fluctuations due to imprecise centrality determination are ...

Coherent diffractive photoproduction of ${ρ}^{0}$ mesons on gold nuclei at 200 GeV/nucleon-pair at the Relativistic Heavy Ion Collider

The STAR Collaboration reports on the photoproduction of ${π}^{+}{π}^{−}$ pairs in gold-gold collisions at a center-of-mass energy of 200 GeV/nucleon-pair. These pion pairs are produced when a nearly real photon emitted by one ion scatters from the other ion.

Author(s): Adam Bzdak and Volker Koch

The dependence of multiproton correlation functions and cumulants on the acceptance in rapidity and transverse momentum is studied. We find that the preliminary data of various cumulant ratios are consistent, within errors, with rapidity and transverse momentum-independent correlation functions. How...
