Determination of the quark coupling strength $∣ V_{u b} ∣$ using baryonic decays

LHCb collaboration, R. Aaij, B. Adeva +707

In the Standard Model of particle physics, the strength of the couplings of the $b$ quark to the $u$ and $c$ quarks, $∣ V_{u b} ∣$ and $∣ V_{c b} ∣$ , are governed by the coupling of the…
