Constraints of Big Bang Nucleosynthesis and Cosmological Observations on varying Higgs VEV

Hongrui Feng, Yudong Luo, Toshitaka Kajino +2

The Higgs vacuum expectation value (VEV) alters both the electroweak and strong interaction rates. We study both effects on Big Bang Nucleosynthesis (BBN) and seek concordance betw…

Electron-capture rates in the medium-mass nuclei Ti, Ni, Zn, and Ge within deformed quasiparticle random-phase approximation

Eunja Ha, Myung-Ki Cheoun, H. Sagawa +2

Electron-capture (EC) rates in medium-mass nuclei are governed by Gamow--Teller (GT) strength distributions and provide important input for stellar weak-interaction processes. In t…

The Sc, Ti, and V Abundance Discrepancy: Testing High-Mass IMF Variation and Massive-Star Rotation

Soonchul Choi, Eda Gjergo, Youngman Kim +1

Scandium, titanium, and vanadium can be synthesized primarily in massive stars. Yet many of the current Galactic chemical evolution models under-produce these elements at early epo…

Impact of experimental mass of Kr on the Se waiting-point in -process

Min Zhang, Yudong Luo, Akira Dohi +5

The recent mass measurement of Kr using the -defined isochronous mass spectrometry yields a mass excess of keV, indicating a 220-keV increase in binding en…

A Systematic Study of Magnetic Fields Impacts on Neutrino Transport in Core-Collapse Supernovae

Yudong Luo, Shuai Zha, Toshitaka Kajino

We quantify the impact of strong magnetic fields (assuming with G) on the neutrino transport in core-collapse supernovae (CCSNe). Magnet…

High Energy Particle Production from Proton Synchrotron Radiation in Strong Magnetic Fields in Relativistic Quantum Field Theory

Tomoyuki Maruyama, A. Baha Balantekin, Myung-Ki Cheoun +4

We investigate photon, pion, and rho-meson production from proton synchrotron radiation in the presence of strong magnetic fields. The proton decay widths and the luminosities of t…
