Global Fit of Modified Quark Couplings to EW Gauge Bosons and Vector-Like Quarks in Light of the Cabibbo Angle Anomaly

Andreas Crivellin, Matthew Kirk, Teppei Kitahara +1

There are two tensions related to the Cabibbo angle of the CKM matrix. First, the determinations of $V_{u s}$ from $K_{μ 2}$ , $K_{ℓ 3}$ , and $τ$ decays disagree at the $3 σ$ level.…

Impact of $Λ_{b} \to Λ_{c} τ ν$ measurement on New Physics in $b \to c l ν$ transitions

Marco Fedele, Monika Blanke, Andreas Crivellin +4

Measurements of the branching ratios of $B \to D^{(*)} τ ν ˉ / B \to D^{(*)} ℓ ν ˉ$ and $B_{c} \to J / ψ τ ν ˉ / B_{c} \to J / ψ ℓ ν ˉ$ by the BaBar, Belle and LHCb collaborations co…

A Precision Relation between $Γ (K \to μ^{+} μ^{-}) (t)$ and $B (K_{L} \to μ^{+} μ^{-}) / B (K_{L} \to γ γ)$

Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +2

We find that the phase appearing in the unitarity relation between $B (K_{L} \to μ^{+} μ^{-})$ and $B (K_{L} \to γ γ)$ is equal to the phase shift in the inte…

Chasing the two-Higgs doublet model in the di-Higgs production

Syuhei Iguro, Teppei Kitahara, Yuji Omura +1

We investigate the di-Higgs production at the Large Hadron Collider in the two-Higgs doublet model (2HDM). In particular, we study the production of an extra neutral Higgs boson $ϕ…

Self-consistent extraction of spectroscopic bounds on light new physics

Cédric Delaunay, Jean-Philippe Karr, Teppei Kitahara +3

Fundamental physical constants are determined from a collection of precision measurements of elementary particles, atoms and molecules. This is usually done under the assumption of…

Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021

Tulika Bose, Antonio Boveia, Caterina Doglioni +318

This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
