Probing a light long-lived pseudo-scalar from Higgs decay via displaced taus at the LHC
Lianyou Shan, Lei Wang, Jin Min Yang +1
A light (GeV mass) long-lived ( around dozens of millimeters) CP-odd scalar can be readily predicted in new physics models. In this work we investigate the Higgs decay into su…
