Lessons from LHCb and Belle II measurements of $B \to J / ψ π$ and $B \to J / ψ K$ decays

Zoltan Ligeti, Yosef Nir, Roy Schein

The LHCb collaboration has recently measured the CP asymmetry in $B^{+} \to J / ψ π^{+}$ decay, while the Belle II collaboration has recently measured the CP asymmetries in $B^{0} \to J / ψ π^{0}$ …

$B_{s}^{0} \to K^{0} K^{0}$ beyond the Standard Model

Yuval Grossman, Yosef Nir, Matthias Neubert +2

Within the Standard Model, the branching fraction of the rare decay $B_{s} \to K^{0} K ˉ^{0}$ is related to other decay rates and CP asymmetries through the approximate $S U (3)$ flavor s…

Lessons from ATLAS and CMS measurements of Higgs boson decays to second generation fermions

Yosef Nir, Purvaash Panduranghan Udhayashankar

There is now experimental evidence for Higgs boson decay into a pair of muons, and significant constraints on the Higgs boson decay into a charm quark-antiquark pair. The data on H…

The flavor of a light charged Higgs

Nicolás Bernal, Marta Losada, Yosef Nir +1

The ATLAS Collaboration has recently reported a search for light-charged Higgs in $t \to H^{+} b$ decay, with $H^{+} \to c b ˉ$ . An excess with a local significance of approximately $3…

Time Dependent CP-even and CP-odd Signatures of Scalar Ultra-light Dark Matter in Neutrino Oscillations

Marta Losada, Yosef Nir, Gilad Perez +2

Scalar ultra-light dark matter (ULDM) interacting with neutrinos can induce, under certain conditions, time-dependent modifications to neutrino oscillation probabilities. The limit…

The branching fraction of $B_{s} \to K^{0} K ˉ^{0}$ : Three puzzles

Yasmine Amhis, Yuval Grossman, Yosef Nir

The branching fraction of the $B_{s} \to K^{0} K ˉ^{0}$ decay has been recently measured by the LHCb and Belle experiments. We study the consistency of the measured value with three rel…
