Searches for baryon number violation in the HIBEAM-NNBAR experiment at the European Spallation Source
Bernhard Meirose
TL;DR
The HIBEAM-NNBAR experiment at the European Spallation Source aims to detect baryon number violation through neutron-antineutron conversions, potentially shedding light on the matter-antimatter asymmetry in the universe.
Contribution
This paper proposes a novel two-stage experimental setup at ESS to search for baryon number violation, leveraging its high neutron flux.
Findings
Design of the HIBEAM-NNBAR experiment for high sensitivity searches
Potential to observe neutron to antineutron conversions
Implications for understanding baryon asymmetry
Abstract
The HIBEAM-NNBAR program is a proposed two-stage experiment at the European Spallation Source (ESS) designed to search for baryon number violation, which is - together with C and CP violation - one of the three fundamental Sakharov conditions to explain the observed baryon asymmetry of the Universe. Taking advantage of the ESS' unique capabilities as the future brightest neutron source, the experiment will make high sensitivity searches for neutrons converting into antineutrons and/or sterile neutrons.
