Exact Methods for Self Interacting Neutrinos
Y. Pehlivan, A. B. Balantekin, Toshitaka Kajino
The effective many-body Hamiltonian which describes vacuum oscillations and self interactions of neutrinos in a two flavor mixing scheme under the single angle approximation has th…
An evaluation of the exposure in nadir observation of the JEM-EUSO mission
J. H. Adams, S. Ahmad, J. -N. Albert +258
We evaluate the exposure during nadir observations with JEM-EUSO, the Extreme Universe Space Observatory, on-board the Japanese Experiment Module of the International Space Station…
7Be charge exchange between 7Be3+ ion and exotic long-lived negatively charged massive particle in big bang nucleosynthesis
Motohiko Kusakabe, K. S. Kim, Myung-Ki Cheoun +2
The existence of an exotic long-lived negatively charged massive particle, i.e., X-, during big bang nucleosynthesis can affect primordial light element abundances. Especially, the…
Neutron stars in a perturbative gravity model with strong magnetic fields
Myung-Ki Cheoun, Cemsinan Deliduman, Can Güngör +4
We investigate the effect of a strong magnetic field on the structure of neutron stars in a model with perturbative gravity. The effect of an interior strong magnetic field…
A Big-Bang Nucleosynthesis Limit on the Neutral Fermion Decays into Neutrinos
Motohiko Kusakabe, A. B. Balantekin, Toshitaka Kajino +1
Using the primordial helium abundance, an upper limit to the magnetic moments for Dirac neutrinos had been provided by imposing restrictions on the number of the additional helicit…
Effects of the density-dependent weak form factors on the neutrino reaction via neutral current for the nucleon in nuclear medium and C
Myung-Ki Cheoun, Ki-Seok Choi, K. S. Kim +4
The nucleon form factors in free space are usually thought to be modified when a nucleon is bound in a nucleus or immersed in a nuclear medium. We investigate effects of the densit…
