The mass difference associated with the oscillation, first observed in this analysis, is one of the smallest mass differences ever measured.
It is curious to note that if the Ξb(6100)– baryon were only 13 MeV heavier, it would be above the Λb0 K- mass threshold.
The highlight of the conference was the new LHCb result on RK based on the full Run 1 and Run 2 data.
The latest analysis represents an improvement in precision thanks to doubling the dataset.
The LHCb collaboration combined several analyses to update branching-fraction measurements for about 50 Bs0 decays.
Andrzej Buras’s new book, Gauge Theory of Weak Decays, is an indispensable travel guide to unexplored territory in weak decays, writes our reviewer.
The collaboration has used Run 2 data to add new exotic states to the tally of tetraquarks previously discovered in B+→J/ψφK+ decays in 2016.
LHCb has recently published a new result on |Vub| using the first ever measurement of the Bs0→K–μ+νμ decay.
Flavour studies have a bright future, concluded conference delegates, who discussed impressive recent results in CP violation and the status of Belle II and upgrades to the LHC experiments.
Work now turns to connecting such observations with the known suppression and regeneration mechanisms in heavy-ion collisions.
