Search for bbb¯b¯ tetraquark decays in 4 muons, B+B−, B0B¯0 and Bs0B¯s0 channels at LHC

We perform a quantitative analysis of the bbb¯b¯ tetraquark decays into hidden- and open-bottom mesons and calculate, for the first time, the bbb¯b¯ tetraquark total decay width. On the basis of our results, we propose the bbb¯b¯→B+B−(B0B¯0)(Bs0B¯s0)→l+l−+X decays as the most suitable channels to ob...
