The Hindered M1 Radiative Decay Υ(2S) → η_b(1S)γ from Lattice NRQCD
Hughes, Ciaran; Dowdall, Rachel J; Davies, Christine TH; Horgan, Ronald Raymond; von, Hippel Georg; Wingate, Matthew Bowen (APSPhysical Review D, 2015-11-03)We present a calculation of the hindered M1 Υ(2S) → η_b(1S)γ decay rate using lattice nonrelativistic QCD. The calculation includes spin-dependent relativistic corrections to the NRQCD action through O(v⁶ ) in the quark’s ...
