Hadron Physics Opportunities at FAIR

J. G. Messchendorp, F. Nerling, P. Achenbach +103

This White Paper outlines a coordinated, decade-spanning programme of hadron and QCD studies anchored at the GSI/FAIR accelerator complex. Profiting from intense deuteron, proton a…

Feasibility of the observation of mesic nuclei in the semi-exclusive C() reaction

Natsumi Ikeno, Yuko Higashi, Hiroyuki Fujioka +7

We study theoretically the feasibility of the semi-exclusive C() reaction for the observation of mesic nuclei using the microscopic transport model JAM.…

Precise lifetime measurement of H hypernucleus using in-flight HeH reaction

T. Akaishi, H. Asano, X. Chen +35

We present a new measurement of the H hypernuclear lifetime using in-flight + He H + reaction at the J-PARC hadron facility. We demonstrat…

Pole position of measured in reactions

PARC E31 Collaboration, S. Aikawa, S. Ajimura +74

We measured a set of , , and invariant mass spectra below and above the mass threshold in -induced reactions on deuteron. We deduced th…

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…
