Survival Probability of Unstable States in Coupled-Channels -- nonexponential decay of "threshold-cusp"
Wren A. Yamada, Osamu Morimatsu, Toru Sato +1
We investigate the survival probability of unstable states, the time-dependence of an initial state, in coupled channels. First, we extend the formulation of the survival probabili…
Derivative expansion in the HAL QCD method for a separable potential
Sinya Aoki, Koichi Yazaki
We investigate how the derivative expansion in the HAL QCD method works to extract physical observables, using a separable potential in quantum mechanics, which is solvable but hig…
Near-threshold Spectrum from Uniformized Mittag-Leffler Expansion -Pole Structure of -
Wren A. Yamada, Osamu Morimatsu, Toru Sato +1
We demonstrate how S-matrix poles manifest themselves as the physical spectrum near the upper threshold in the context of the two-channel uniformized Mittag-Leffler expansion, an e…
Hermitizing the HAL QCD potential in the derivative expansion
Sinya Aoki, Takumi Iritani, Koichi Yazaki
A formalism is given to hermitize the HAL QCD potential, which needs to be non-hermitian except the leading order (LO) local term in the derivative expansion as the Nambu-Bethe-Sal…
Exotic Hadrons from Heavy Ion Collisions
ExHIC Collaboration, Sungtae Cho, Tetsuo Hyodo +12
Heavy ion collisions (HIC) at high energies are excellent ways for producing heavy hadrons and composite particles. With upgraded detectors at RHIC and LHC, it has become possible…
Revision of the brick wall method for calculating the black hole thermodynamic quantities
F. Lenz, K. Ohta, K. Yazaki
Within the framework of the "brick wall model", a novel method is developed to compute the contributions of a scalar field to the thermodynamic quantities of black holes. The relat…
