Effect of Long-lived Strongly Interacting Relic Particles on Big Bang Nucleosynthesis
Motohiko Kusakabe, Toshitaka Kajino, Takashi Yoshida +1
It has been suggested that relic long-lived strongly interacting massive particles (SIMPs, or particles) existed in the early universe. We study effects of such long-lived unst…
Neutrino-Nucleus Reaction Cross Sections for Light Element Synthesis in Supernova Explosions
T. Yoshida, T. Suzuki, S. Chiba +5
The neutrino-nucleus reaction cross sections of 4He and 12C are evaluated using new shell model Hamiltonians. Branching ratios of various decay channels are calculated to evaluate…
New Constraints on Radiative Decay of Long-Lived Particles in Big Bang Nucleosynthesis with New He Photodisintegration Data
Motohiko Kusakabe, Toshitaka Kajino, Takashi Yoshida +3
A recent measurement of He photodisintegration reactions, He(,)H and He(,)He with laser-Compton photons shows smaller cross sections than those esti…
A Simultaneous Solution to the ^6Li and ^7Li Big Bang Nucleosynthesis Problems from a Long-Lived Negatively-Charged Leptonic Particle
Motohiko Kusakabe, Toshitaka Kajino, Richard N. Boyd +2
The Li abundance observed in metal poor halo stars exhibits a plateau similar to that for Li suggesting a primordial origin. However, the observed abundance of Li is a…
Neutrino Nucleus Reactions based on New Shell Model Hamiltonians
Toshio Suzuki, Satoshi Chiba, Takashi Yoshida +2
A new shell model Hamiltonian for p-shell nuclei which properly takes into account important roles of spin-isospin interactions is used to obtain cross sections of neutrino-^12C re…
Neutrino Oscillation Effects on Supernova Light Element Synthesis
T. Yoshida, T. Kajino, H. Yokomakura +3
Neutrino oscillations affect light element synthesis through the neutrino-process in supernova explosions. The 7Li and 11B yields produced in a supernova explosion of a 16.2 solar-…
