Flavor Neutrino Masses giving sinθ_{13}=0
Keisuke Yuda, Masaki Yasue
Among neutrino mixings, the reactor mixing angle, θ_{13}, is observed to be almost vanishing and is consistent with θ_{13}=0. We discuss how the condition of θ_{13}=0 constrains mo…
Hourava-Lifshitz Gravity on Primordial Black Holes
Hikoya Kasari, Takehiko T. Fujishiro
We tested the Hourava Lifshitz (HL) quantum gravity model by using the L{\" u}, Mei and Pope solutions for primordial black holes (PBHs) and the observational upper bounds of the P…
Dilatonic Inflation, Gravitino and Reheating in Modified Modular invariant Supergravity
Yuta Koshimizu, Toyokazu Fukuoka, Kenji Takagi +2
A new modified string-inspired modular invariant supergravity model is proposed and is applied to realize the slow roll inflation in Einstein frame, so that the model explains WMAP…
Kaon fragmentation function from NJL-jet model
Hrayr H. Matevosyan, Anthony W. Thomas, Wolfgang Bentz
The NJL-jet model provides a sound framework for calculating the fragmentation func- tions in an effective chiral quark theory, where the momentum and isospin sum rules are satisfi…
Sufficient conditions for open manifolds to be diffeomorphic to Euclidean spaces
Kei Kondo, Minoru Tanaka
Let M be a complete non-compact connected Riemannian n-dimensional manifold. We first prove that, for any fixed point p in M, the radial Ricci curvature of M at p is bounded from b…
