It is shown that the strong isospin dependence observed in pion absorption on He3 can be described by the two-body mechanism πNNΔNNN. The effect of the three-body mechanism is also calculated but found to be negligibly small. The ΔNNN dynamics consistently determined from NN inelasticities is shown to be essential to understand the isospin dependence.

Heating up of Superconductors
January 27, 2017

This collection marks the 30th anniversary of the discovery of high-temperature superconductors. The papers selected highlight some of the advances that have been made to date, both in understanding why these compounds behave in the way they do, and in utilizing them in applications. The papers included in the collection have been made free to read.

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.
