Enrico Bertuzzo, Ana Luisa Foguel, Gabriel M. Salla, Renata Zukanovich Funchal
TL;DR
This paper establishes new experimental bounds on leptophilic axionlike particles and Majorons using ArgoNeuT data, significantly constraining their possible properties in the 0.2 to 1.7 GeV mass range.
Contribution
It provides the first constraints from ArgoNeuT on these particles, improving the limits in the specified mass range.
Findings
Bounds are the most restrictive in the 0.2-1.7 GeV mass range.
ArgoNeuT data constrains leptophilic axionlike particles and Majorons.
New limits surpass previous experimental constraints.
Abstract
Axionlike particles are among the most studied extensions of the standard model. In this Letter we study the bounds that the ArgoNeuT experiment can put on the parameter space of two specific scenarios: leptophilic axionlike particles and Majorons. We find that such bounds are currently the most constraining ones in the (0.2 - 1.7) GeV mass range.
