Recursion Relations in Liouville Gravity coupled to Ising Model satisfying Fusion Rules
K. Hamada
The recursion relations of 2D quantum gravity coupled to the Ising model discussed by the author previously are reexamined. We study the case in which the matter sector satisfies t…
Search for oscillations with the OPERA experiment in the CNGS beam
OPERA collaboration, N. Agafonova, A. Aleksandrov +161
A first result of the search for \numu \nue oscillations in the OPERA experiment, located at the Gran Sasso Underground Laboratory, is presented. The experiment looke…
Gravitational Collapse in 1+1 Dimensions and Quantum Gravity
K. Hamada
We investigate the quantum theory of 1+1 dimensional dilaton gravity, which is an interesting toy model of the black hole dynamics. The functional measures of gravity part are expl…
Measurement of the neutrino velocity with the OPERA detector in the CNGS beam
The OPERA Collaboration, T. Adam, N. Agafonova +188
The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km. The measureme…
Vertex Operators for Super Yang-Mills and Multi D-Branes in Green-Schwarz Superstring
K. Hamada
We study vertex operators for super Yang-Mills and multi D-branes in covariant form using Green-Schwarz formalism. We introduce the contact terms naturally and prove space-time sup…
Quantum Theory of Dilaton Gravity in 1+1 Dimensions
K. Hamada
We discuss the quantum theory of 1+1 dimensional dilaton gravity, which is an interesting model with analogous features to the spherically symmetric gravitational systems in 3+1 di…
A Gravitational Lens Model for the Lya Emitter, LAE 221724+001716 at z=3.1 in the SSA 22 Field
Y. Nakahiro, Y. Taniguchi, A. K. Inoue +8
During the course of our Lyman continuum imaging survey, we found that the spectroscopically confirmed Lya emitter LAE 221724+001716 at z = 3.10 in the SSA 22 field shows strong Ly…
Measurement of the neutrino velocity with the OPERA detector in the CNGS beam using the 2012 dedicated data
The OPERA Collaboration, T. Adam, N. Agafonova +168
In spring 2012 CERN provided two weeks of a short bunch proton beam dedicated to the neutrino velocity measurement over a distance of 730 km. The OPERA neutrino experiment at the u…
Comparative study of macroscopic quantum tunneling in Bi_2Sr_2CaCu_2O_y intrinsic Josephson junctions with different device structures
K. Ota, K. Hamada, R. Takemura +6
We investigated macroscopic quantum tunneling (MQT) of BiSrCaCuO intrinsic Josephson junctions (IJJs) with two device structures. One is a nanometer-thick small mes…
Measurement of the atmospheric muon charge ratio with the OPERA detector
OPERA Collaboration, N. Agafonova, A. Anokhina +182
The OPERA detector at the Gran Sasso underground laboratory (LNGS) was used to measure the atmospheric muon charge ratio in the TeV energy region. We analyzed 403069 atmospheric mu…
Quantum Gravity and Black Hole Dynamics in 1+1 Dimensions
K. Hamada, A. Tsuchiya
We study the quantum theory of 1+1 dimensional dilaton gravity, which is an interesting toy model of the black hole dynamics. The functional measures are explicitly evaluated and t…
