Angular analysis of the $B^{+} \to K^{*+} μ^{+} μ^{-}$ decay

LHCb collaboration, R. Aaij, C. Abellán Beteta +959

We present an angular analysis of the $B^{+} \to K^{*+} (\to K_{S}^{0} π^{+}) μ^{+} μ^{-}$ decay using 9$\,\mbox{fb}^{-1}$ of $pp$ collision data collected with the L…

Observation of the $B_{s}^{0} \to D^{*\pm} D^{\mp}$ decay

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

A search for the $B_{s}^{0} \to D^{*\pm} D^{\mp}$ decay is performed using proton-proton collision data at centre-of-mass energies of $7$ , $8$ and $13 TeV$ collected by…

Evidence of a $J / ψ Λ$ structure and observation of excited $Ξ^{-}$ states in the $Ξ_{b}^{-} \to J / ψ Λ K^{-}$ decay

LHCb collaboration, R. Aaij, C. Abellán Beteta +959

First evidence of a structure in the $J / ψ Λ$ invariant mass distribution is obtained from an amplitude analysis of $Ξ_{b}^{-} \to J / ψ Λ K^{-}$ decays. The observed s…

Observation of $C P$ violation in two-body $B_{(s)}^{0}$ -meson decays to charged pions and kaons

LHCb collaboration, R. Aaij, C. Abellán Beteta +966

The time-dependent $C P$ asymmetries of $B^{0} \to π^{+} π^{-}$ and $B_{s}^{0} \to K^{+} K^{-}$ decays are measured using a data sample of $pp$ collisions corresponding to an integrated lu…

The Search for Feebly-Interacting Particles

Gaia Lanfranchi, Maxim Pospelov, Philip Schuster

At the dawn of a new decade, particle physics faces the challenge of explaining the mystery of dark matter, the origin of matter over antimatter in the Universe, the apparent fine-…
