First search for $B \to X_{s} I^½ I^ˉ ½$ decays

Belle II Collaboration, M. Abumusabh, I. Adachi +440

We report the first search for the flavor-changing neutral-current decays $B \to X_{s} I^½ I^ˉ ½$ , where $X_{s}$ is a hadronic system with strangeness equal to 1, in data co…

Multiplicity dependence of prompt and non-prompt J/ $I ¨ $ production at midrapidity in pp collisions at $s = 13$ TeV

ALICE Collaboration

The yields of prompt and non-prompt J/ $I ¨ $ and the fraction of non-prompt J/ $I ¨ $ are measured at midrapidity ( $∣ y ∣ < 0.9$ ) via the dielectron decay channel as a function of the mid…

A search for feebly-interacting particles in $B$ decays with missing energy at Belle

Belle, Belle II Collaborations, : +406

We present a search for an invisible hidden-sector particle $X_{inv}$ , produced in $B^{0} \to D ˉ^{0} X_{inv}$ and $B^{\pm} \to h X_{inv}$ decays, where $h = I ¨ ^{\pm}$ ,…

Multiplicity dependence of charged-particle intra-jet properties in pp collisions at $s$ = 13 TeV

ALICE Collaboration

The first measurement of the multiplicity dependence of intra-jet properties of leading charged-particle jets in proton-proton (pp) collisions is reported. The mean charged-particl…
