Prospects for B s 0 $$ {B}_{(s)}^0 $$ → π 0 π 0 and B s 0 $$ {B}_{(s)}^0 $$ → ηη modes and corresponding CP asymmetries at Tera-Z

Abstract The physics potential of measuring B s 0 $$ {B}_{(s)}^0 $$ → π 0 π 0 and B s 0 $$ {B}_{(s)}^0 $$ → ηη decays via four-photon final states at Tera-Z phase of CEPC or FCC-ee is investigated in this paper. We propose an electromagnetic calorimeter (ECAL) with both high energy resolution and ex...
