Pion-nucleon sigma term and deeply bound pionic atoms
Natsumi Ikeno, Takahiro Nishi, Kenta Itahashi +3
We investigate the possibility to determine the value of the pion-nucleon sigma term precisely by the experimental observables of the deeply bound pionic atoms. We discuss…
Chiral symmetry restoration at high matter density observed in pionic atoms
Takahiro Nishi, Kenta Itahashi, DeukSoon Ahn +45
Modern theories of physics tell that the vacuum is not an empty space. Hidden in the vacuum is a structure of anti-quarks and quarks . The and pair has t…
Spectral structure of singular spectrum decomposition for time series
Kenji Kume, Naoko Nose-Togawa
Singular spectrum analysis (SSA) is a nonparametric and adaptive spectral decomposition of a time series. The singular value decomposition of the trajectory matrix and the anti-dia…
Filter characteristics in image decomposition with singular spectrum analysis
Kenji Kume, Naoko Nose-Togawa
Singular spectrum analysis is developed as a nonparametric spectral decomposition of a time series. It can be easily extended to the decomposition of multidimensional lattice-like…
Nuclear Quadrupole Effects in Deeply Bound Pionic Atoms
N. Nose-Togawa, S. Hirenzaki, K. Kume
We have studied nuclear quadrupole deformation effects in deeply bound pionic atoms theoretically. We have evaluated the level shifts and widths of the hyperfine components using t…
