Neutrino Masses in the Supersymmetric Standard Model with Right-Handed Neutrinos and Spontaneous R-Parity Violation
Ryuichiro Kitano, Kin-ya Oda
We propose an extension of the supersymmetric standard model with right-handed neutrinos and a singlet Higgs field, and study the neutrino masses in this model. The Majorana masses…
General relativistic effects on neutrino-driven wind from young, hot neutron star and the r-process nucleosynthesis
Kaori Otsuki, Hideyuki Tagoshi, Toshitaka Kajino +1
Neutrino-driven wind from young hot neutron star, which is formed by supernova explosion, is the most promising candidate site for r-process nucleosynthesis. We study general relat…
Period Measurement of AGB Stars in the Outer Galactic Disk
Jun-ichi Nakashima, B. W. Jiang, Shuji Deguchi +2
Light variation of the 47 AGB star candidates in the outer Galactic disk has been monitored at I-band for 5 years. Periods were determined well for 18 of them and less reliably for…
Meson Synchrotron Emission from Central Engines of Gamma-Ray Bursts with Strong Magnetic Fields
Akira Tokuhisa, Toshitaka Kajino
Gamma-ray bursts (GRBs) are presumed to be powered by still unknown central engines for the timescales in the range a few s. We propose that the GRB central engines woul…
Phase Transition of 4D Simplicial Quantum Gravity with U(1) Gauge Field
H. S. Egawa, S. Horata, N. Tsuda +1
The phase transition of 4D simplicial quantum gravity coupled to U(1) gauge fields is studied using Monte-Carlo simulations. The phase transition of the dynamical triangulation mod…
Evolution of Beryllium and Boron in the Inhomogeneous Early Galaxy
Takeru Ken Suzuki, Yuzuru Yoshii, Toshitaka Kajino
A model of supernova-driven chemical evolution of the Galactic halo, recently proposed by Tsujimoto, Shigeyama, & Yoshii (1999, ApJL, 519, 64), is extended in order to investigate…
