Low-energy neutrino responses for 71Ga by electron capture rates, charge exchange reactions and shell model calculations
Yoritaka Iwata, Hiroyasu Ejiri, Shahariar Sarkar
Weak Gamow-Teller (GT) responses for low-lying states in are crucial for studying low-energy solar neutrinos and the Ga anomaly, i.e., the possible transition…
The study of decay of Xe using nonclosure approach in nuclear shell model
S. Sarkar, Y. Iwata, K. Jha +1
In this investigation, we compute the nuclear matrix elements (NMEs) relevant to the light neutrino-exchange mechanism governing neutrinoless double beta () decay in …
Nuclear matrix elements calculation for decay of Sn using nonclosure approach in nuclear shell model
Shahariar Sarkar, P. K. Rath, V. Nanal +5
In this study, we calculate the nuclear matrix elements (NMEs) for the light neutrino-exchange mechanism of neutrinoless double beta ) decay of Sn within the framewor…
Effect of Spin-Dependent Short-Range Correlations on Nuclear Matrix Elements for Neutrinoless Double Beta Decay of Ca
S. Sarkar, Y. Iwata
The neutrinoless double beta decay is a pivotal weak nuclear process that holds the potential to unveil the Majorana nature of neutrinos and predict their absolute masses. In this…
Recurrence formula for some higher order evolution equations
Yoritaka Iwata
Riccati's differential equation is formulated as abstract equation in finite or infinite dimensional Banach spaces. Since the Riccati's differential equation with the Cole-Hopf tra…
Unbounded generalization of the Baker-Campbell-Hausdorff formulae
Yoritaka Iwata
Based on the operator representation on the module over Banach algebra , the Campbell-Baker-Hausdorff formula is generalized to the unbounded situations. In conclusion, by me…
Antisymmetric tensor generalizations of affine vector fields
Tsuyoshi Houri, Yoshiyuki Morisawa, Kentaro Tomoda
Tensor generalizations of affine vector fields called symmetric and antisymmetric affine tensor fields are discussed as symmetry of spacetimes. We review the properties of the symm…
Relativistic Gravitational Collapse of a Cylindrical Shell of Dust II: Settling Down Boundary Condition
Ken-ichi Nakao, Tomohiro Harada, Yasunari Kurita +1
We numerically study the dynamics of an imploding hollow cylinder composed of dust. Since there is no cylindrical black hole in 4-dimensional spacetime with physically reasonable e…
Kerr-Schild ansatz in Einstein-Gauss-Bonnet gravity: An exact vacuum solution in five dimensions
Andres Anabalon, Nathalie Deruelle, Yoshiyuki Morisawa +4
As is well-known, Kerr-Schild metrics linearize the Einstein tensor. We shall see here that they also simplify the Gauss-Bonnet tensor, which turns out to be only quadratic in the…
Charged Rotating Kaluza-Klein Black Holes Generated by G2(2) Transformation
Shinya Tomizawa, Yukinori Yasui, Yoshiyuki Morisawa
Applying the G_{2(2)} generating technique for minimal D=5 supergravity to the Rasheed black hole solution, we present a new rotating charged Kaluza-Klein black hole solution to th…
Boundary Value Problem for Black Rings
Yoshiyuki Morisawa, Shinya Tomizawa, Yukinori Yasui
We study the boundary value problem for asymptotically flat stationary black ring solutions to the five-dimensional vacuum Einstein equations. Assuming the existence of two additio…
Cosmological Black Holes on Taub-NUT space in Five-Dimensional Einstein-Maxwell Theory
Daisuke Ida, Hideki Ishihara, Masashi Kimura +3
The cosmological black hole solution on the Gibbons-Hawking space has been constructed. We also investigate the properties of this solution in the case of a single black hole. Unli…
Relativistic Gravitational Collapse of a Cylindrical Shell of Dust
Ken-ichi Nakao, Yasunari Kurita, Yoshiyuki Morisawa +1
The gravitational collapse of a thick cylindrical shell of dust matter is investigated. It is found that a spacetime singularity forms on the symmetry axis and that it is necessari…
Zero-mode Spectrum of Eleven-dimensional Theory on the Plane-wave Background
Tetsuji Kimura
In this doctoral thesis we study zero-mode spectra of Matrix theory and eleven-dimensional supergravity on the plane-wave background. This background is obtained via the Penrose li…
Kahler Potentials on Toric Varieties
Tetsuji Kimura
One has believed that low energy effective theories of the Higgs branch of gauged linear sigma models correspond to supersymmetric nonlinear sigma models, which have been already i…
