Phys. Rev. C 88, 025205 – Published 19 August 2013


The K+K final state interaction was investigated based on both the K+K invariant mass distributions measured at excess energies of Q=10 and 28 MeV and the near threshold excitation function for the ppppK+K reaction. The K+K final state enhancement factor was parametrized using the effective range expansion. The effective range of the K+K interaction was estimated to be Re(bK+K)=0.1±0.4stat±0.3sysfm and Im(bK+K)=1.20.2stat0.0sys+0.1stat+0.2sysfm, and the determined real and imaginary parts of the K+K scattering length amount to Re(aK+K)=8.04.0stat+6.0statfm and Im(aK+K)=0.05.0stat+20.0statfm.

Discontinuation of Brief Reports in Physical Review C
March 17, 2015

Starting July 1, 2015, Physical Review C (PRC) is discontinuing its Brief Reports section. Beginning on April 1, 2015, PRC will consider new submissions to the Brief Reports section as short regular articles.

APS and CERN Sign Open Access Agreement for SCOAP3

APS and CERN, the host organization of SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics), have signed an agreement to make the high-energy physics (HEP) articles published in three leading APS journals open access beginning January 1, 2018. This agreement acts to support the publishing of open access content for wider benefit of the HEP community.
