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…
Spectroscopy of pionic atoms in reaction and angular dependence of the formation cross sections
T. Nishi, K. Itahashi, G. P. A. Berg +36
We observed the atomic and states of bound to nuclei as distinct peak structures in the missing mass spectra of the ${}^{122}{\rm Sn}(d,{}^3{\rm…
Missing-mass spectroscopy of the reaction near the -meson production threshold
Y. K. Tanaka, K. Itahashi, H. Fujioka +51
Excitation-energy spectra of C nuclei near the -meson production threshold have been measured by missing-mass spectroscopy using the C(,) reaction. A…
Measurement of excitation spectra in the C reaction near the emission threshold
Y. K. Tanaka, K. Itahashi, H. Fujioka +51
Excitation spectra of C were measured in the C reaction near the emission threshold. A proton beam extracted from the synchrotron SIS-18 at GSI with an in…
Search for η'(958)-nucleus bound states by (p,d) reaction at GSI and FAIR
H. Fujioka, Y. Ayyad, J. Benlliure +51
The mass of the η' meson is theoretically expected to be reduced at finite density, which indicates the existence of η'-nucleus bound states. To investigate these states, we perfor…
