Parity violation in radiative neutron capture on the deuteron

Abstract

Parity violating (PV) effects in neutron-deuteron radiative capture are studied using Desplanques, Donoghue, and Holstein (DDH) and effective field theory (EFT) weak potentials. The values of PV effects are calculated using wave functions, obtained by solving three-body Faddeev equations in configuration space for realistic strong potentials. The relations between physical observables and low-energy constants are presented, and dependencies of the calculated PV effects on strong and weak potentials are discussed. The presented analysis shows the possible reason for the existing discrepancy in PV nuclear data analysis using the DDH approach and reveals a new opportunity to study short range interactions in nuclei.

Parity-violating photon circular polarization in nd $\rightarrow$ 3H $\gamma$ with effective field theory at thermal energy

“…Recently, the PV effects in nd → 3 Hγ were calculated for DDH and EFT weak interaction potentials [12]. We compare these P γ values with our results in sect.V.…”

“…Recently, the value of P γ in nd → 3 Hγ is calculated with the DDH-best parameter values and 4-parameter fits for the different potential models in ref. [12]. The order of magnitude of the results of P γ in the ref.…”

Nuclear electric dipole moment of three-body systems

“…As increasing the parameter Λ, the result become more sensitive to the short range details of a potential model. The largest deviation for the INOY potential was also observed for matrix elements calculated for parity violating radiative neutron capture [22]. However, unlike to the case of parity violating radiative capture, the EDM matrix elements do not show significant dependence at short distances for local strong potentials.…”

Multiplicity fluctuation and correlation of mesons and baryons in ultra-relativistic heavy-ion collisions at the LHC

“…The mechanism assumes the effective absence of soft gluon quanta at hadronization and the effective degrees of freedom of QCD matter are quarks and antiquarks with constituent masses at hadronization. Application of quark combination to the bulk quark system produced in relativistic A+A collisions is natural in picture, and QCM has good performance in explaining or reproducing the data of transverse momentum spectra, yields and longitudinal rapidity distributions for various identified hadrons [24,25,[29][30][31][32][33][34][35][36][37][38][39]. In this paper, we do not intend to discuss the space-time details of the combination as those in Refs.…”
