Flash from the Past: New Gamma-Ray Constraints on Light CP-even Scalar from SN1987A
Yue Yu, Writasree Maitra, P. S. Bhupal Dev +4
We derive new constraints on light CP-even scalars using old gamma-ray observations in the direction of SN1987A by the Solar Maximum Mission (SMM) satellite. Light scalars can be a…
