Microscopic study of fusion reactions with a weakly bound nucleus: Effects of deformed halo

Xiang-Xiang Sun (孙向向) and Lu Guo (郭璐)

Phys. Rev. C 107, L011601 (2023) - Published 4 January, 2023

New modeling explains the relatively high fusion reaction probabilities of halo nuclei, which are composed of a dense core surrounded by a “satellite” of one or two nucleons.

Densities and momentum distributions in A12 nuclei from chiral effective field theory interactions

M. Piarulli, S. Pastore, R. B. Wiringa, S. Brusilow, and R. Lim

Phys. Rev. C 107, 014314 (2023) - Published 20 January, 2023

This study presents calculations of one- and two-body densities in both coordinate and momentum space for various nuclei up to 12C, using the phenomenological AV18+UX and various Norfolk NN + NNN χEFT interactions. It features new calculations of the pair density as a function of both pair separation and center-of-mass, as well as the two-body momentum distribution for short- and long-range pairs differentiated by a pair separation boundary. The full set of results are available online for general use by the nuclear physics community and are intended to provide useful insights into the short-range structure of nuclei and various reaction processes.

KamNet: An integrated spatiotemporal deep neural network for rare event searches in KamLAND-Zen

A. Li, Z. Fu, C. Grant, H. Ozaki, I. Shimizu, H. Song, A. Takeuchi, and L. A. Winslow

Phys. Rev. C 107, 014323 (2023) - Published 30 January, 2023

Searches for rare events employ customized detectors with large fiducial mass to effectively reduce background. Leveraging recent breakthroughs in geometric deep learning and spatiotemporal analysis, this work presents a novel machine-learning algorithm (KamNet) as a new, robust tool to maximize the information provided by the kiloton-scale KamLAND liquid-scintillator detector. Adding a so-called “attention mechanism” to KamNet, the authors demonstrate that this enhanced machine-learning approach can increase the sensitivity of the KamLAND-Zen experiment to zero-neutrino- and two-neutrino double-β decay. That mechanism also elucidates the underlying physics KamNet is using for background rejection.

Multinucleon transfer mechanism in Cf250+Th232 collisions using the quantal transport description based on the stochastic mean-field approach

S. Ayik, M. Arik, O. Yilmaz, B. Yilmaz, and A. S. Umar

Phys. Rev. C 107, 014609 (2023) - Published 10 January, 2023

The production of elements close to the superheavy island of stability, with Z>100, is one of the most appealing challenges in nuclear physics. Based on a stochastic extension of the time-dependent Hartree-Fock theory, this article presents accurate microscopic calculations of multinucleon transfer for the 250Cf+232Th system at Ec.m.=950 MeV. Isotope production cross sections are described without any adjustable parameters, thus providing a benchmark to new experimental searches.

Confronting anomalous kaon correlations measured in Pb-Pb collisions at sNN=2.76 TeV

Joseph I. Kapusta, Scott Pratt, and Mayank Singh

Phys. Rev. C 107, 014913 (2023) - Published 30 January, 2023

This paper uses simple models to interpret recent measurements of anomalously strong correlations between neutral and charged kaon production performed at the LHC for high-energy heavy-ion collisions. Thermal models, including charge conservation effects, are found to be insufficient to explain the data for the most central collisions. More exotic conjectures involving coherent emission can reproduce the observations if 30% of the kaons are emitted from coherent sources in the most central collisions. Such coherence might be related to the melting and re-freezing of the QCD vacuum.

Ab initio calculation of the β-decay spectrum of He6

G. B. King, A. Baroni, V. Cirigliano, S. Gandolfi, L. Hayen, E. Mereghetti, S. Pastore, and M. Piarulli

Phys. Rev. C 107, 015503 (2023) - Published 27 January, 2023

Searches for new physics can be conducted by brute force or, like the perihelion shift of Mercury, looking for subtle but persistent discrepancies. This detailed paper carries out high-precision calculations of the β-decay spectrum of 6He, and estimates the experimental precision needed to reveal hints of charged-current interactions beyond the Standard Model and/or sterile neutrinos.

Fermi operator expansion method for nuclei and inhomogeneous matter with a nuclear energy density functional

Takashi Nakatsukasa

Phys. Rev. C 107, 015802 (2023) - Published 9 January, 2023

Calculations for nuclear structure at high excitation energy or of nuclear matter in explosive stellar phenomena and neutron stars require intensive computations. The author tests the performance of a numerical method based on Fermi operator expansion that requires neither diagonalization nor Gram-Schmidt orthonormalization. The approach is suitable for massively parallel computing with distributed memory, and the calculations promise to scale well for large space sizes. Applied to finite nuclei and inhomogeneous nuclear matter, the method is efficient at high temperature, and the calculations clearly show the liquid-gas phase transition.

Searches for new physics can be conducted by brute force or, like the perihelion shift of Mercury, looking for subtle but persistent discrepancies. This detailed paper carries out high-precision calculations of the β-decay spectrum of 6He, and estimates the experimental precision needed to reveal hints of charged-current interactions beyond the Standard Model and/or sterile neutrinos.

Calculations for nuclear structure at high excitation energy or of nuclear matter in explosive stellar phenomena and neutron stars require intensive computations. The author tests the performance of a numerical method based on Fermi operator expansion that requires neither diagonalization nor Gram-Schmidt orthonormalization. The approach is suitable for massively parallel computing with distributed memory, and the calculations promise to scale well for large space sizes. Applied to finite nuclei and inhomogeneous nuclear matter, the method is efficient at high temperature, and the calculations clearly show the liquid-gas phase transition.
