Search for $GeV$ -scale axion-like particles in PbPb collisions

LHCb collaboration, R. Aaij, M. Abdelfatah +1161

A search is performed for the production of axion-like particles with masses in the range 3-10 GeV using PbPb collision data recorded by the LHCb experiment, corresponding to an in…

Energy-energy correlators within $Z$ -tagged jets in proton-proton collisions at $s$ = 13 TeV

LHCb collaboration, R. Aaij, M. Abdelfatah +1161

Energy-energy correlators probe perturbative and nonperturbative QCD regimes of jet formation through momentum-weighted angular correlations between hadrons. First measurements in…

Observation of $Ξ_{b}^{0} \to Ξ^{0} J / ψ$ and evidence for $Ξ_{b}^{0} \to Ξ^{0} ψ (2 S)$ decays

LHCb collaboration, R. Aaij, M. Abdelfatah +1159

The first search for the beauty baryon decays $Ξ_{b}^{0} \to Ξ^{0} J / ψ$ and $Ξ_{b}^{0} \to Ξ^{0} ψ (2 S)$ is presented using the proton-proton collision dataset collected by the LHCb…

Stringent limits on $C P T$ - and Lorentz-invariance violation from $B_{s}^{0}$ meson decays

LHCb collaboration, R. Aaij, M. Abdelfatah +1161

Tests of fundamental symmetries, such as $C P T$ and Lorentz invariance, provide sensitive probes of physics beyond the standard quantum-field-theory framework. Possible violations…

First measurement of the ratio of $ψ (2 S)$ -to- $J / ψ$ inclusive production in $p Ar$ and $pp$ collisions at $s_{NN} = 113 GeV$ with SMOG2

LHCb collaboration, R. Aaij, M. Abdelfatah +1162

A measurement of the $ψ (2 S)$ -to- $J / ψ$ production cross-section ratio is performed in proton-argon ( $p Ar$ ) and proton-proton ( $pp$ ) collisions in fixed-target mode at $\sqr…
