Search for hidden-sector bosons in $B^{0} \to K^{* 0} μ^{+} μ^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +724

A search is presented for hidden-sector bosons, $χ$ , produced in the decay $B^{0} \to K^{*} (892)^{0} χ$ , with $K^{*} (892)^{0} \to K^{+} π^{-}$ and $χ \to μ^{+} μ^{-}$ . The search is performed u…

Observation of $J / ψ p$ resonances consistent with pentaquark states in $Λ_{b}^{0} \to J / ψ K^{-} p$ decays

LHCb collaboration, R. Aaij, B. Adeva +720

Observations of exotic structures in the $J / ψ p$ channel, that we refer to as pentaquark-charmonium states, in $Λ_{b}^{0} \to J / ψ K^{-} p$ decays are presented. The data sample corresponds…

$B$ flavour tagging using charm decays at the LHCb experiment

LHCb collaboration, R. Aaij, B. Adeva +725

An algorithm is described for tagging the flavour content at production of neutral $B$ mesons in the LHCb experiment. The algorithm exploits the correlation of the flavour of a $B$ …

Measurement of the branching fraction ratio $B (B_{c}^{+} \to ψ (2 S) π^{+}) / B (B_{c}^{+} \to J / ψ π^{+})$

LHCb collaboration, R. Aaij, B. Adeva +721

Using $pp$ collision data collected by LHCb at center-of-mass energies $s$ = 7 TeV and 8 TeV, corresponding to an integrated luminosity of 3 fb $^{- 1}$ , the ratio of the bran…

Search for long-lived heavy charged particles using a ring imaging Cherenkov technique at LHCb

LHCb collaboration, R. Aaij, B. Adeva +701

A search is performed for heavy long-lived charged particles using 3.0 fb $^{- 1}$ of pp collisions collected at $s$ = 7 and 8 TeV with the LHCb detector. The search is mainly…
