B2ll lines and B2llgamma
B2mumu (also same-sign), B2hh, B2ee (also same-sign), B2emu (also same-sign) and the corresponding B2llgamma lines. The mass windows are large enough to cover B0 and Bs decays (in spite of the decay descriptor being Bs)
B2mumu and B2hh use Flavour Tagging
Lines inspired by Run 2 Stripping with the aim to allow lower lifetimes (favourable for B2hh and B2mumu TD-CPV studies).

For the radiative lines (that have zero rates) I have tested on the standard minbias sample with a significantly loosened BIPCHI2 (<1000)

So the selection does work. But I was not able to run over the (ancient) B2mumugamma sample.
