Deltas in hadron gas

K. G. Denisenko and St. Mrowczyński

Phys. Rev. C 35, 1932 – Published 1 May 1987

Abstract

The relation between the author’s transport theory approach to the systems with unstable particles and the S-matrix formulation of statistical mechanics is established. Then, the equilibrium characteristics of a classical gas of nucleons, deltas, and pions are studied. The finiteness of the delta decay width is taken into account. It is shown that if one treats the delta isobars as stable particles their number is significantly underestimated at the temperatures smaller than about 60 MeV.

APS and the Physical Review Editorial Office Continue to Support Researchers

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.

We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy.

Ways to Access APS Journal Articles Off-Campus

Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals. To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions.
