A New Silicon Drift Detector For Kaonic Deuterium Measurements: On behalf of the E57 collaboration at J-PARC
Stefan Meyer Institute, Vienna, Austria
Published online: 25 June 2018
The interaction of antikaons with nucleons and nuclei in the lowenergy regime is a very active research field in hadron physics. Specially, the antikaon-nucleon interaction close to threshold provides crucial information on the interplay between spontaneous and explicit chiral symmetry breaking in low-energy QCD and touching one of the fundamental problems in hadron physic today - the still unsolved question of how hadron masses are generated. To study this problem, we have developed a new X–ray detector system and constructed an experimental apparatus to measure the kaonic deuterium 1s ground state shift and width with an accuracy of 60 eV and 140 eV, respectively.
