A CKM blind spot: probing $b$ -column rescaling with kaons

Avital Dery

CKM unitarity triangle constraints are insensitive to New Physics scenarios in which the $b$ -column is uniformly rescaled. This is because B physics data over-constrain the angles…

CP violation in $K \to μ^{+} μ^{-}$ with and without time dependence through a tagged analysis

Giancarlo D'Ambrosio, Avital Dery, Yuval Grossman +4

We point out that using current knowledge of $B (K_{L}^{0} \to μ^{+} μ^{-})$ and $B (K_{L}^{0} \to γ γ)$ , one can extract short-distance information from the combined measurement of th…

Majorana phases beyond neutrinoless double beta decay

Avital Dery, Stefania Gori, Yuval Grossman +1

The $ν_{M} SM$ is defined as the SM extended to include dimension-5 operators. In this model neutrino masses violate lepton number, and two parameters of the lepton mixing matri…

$K \to μ^{+} μ^{-}$ as a third kaon golden mode

Avital Dery

Recent progress has demonstrated that the $K \to μ^{+} μ^{-}$ decay carries clean short-distance information, attainable from a measurement of time-dependence sensitive to $K_{L} - K_{S}$ inter…

Revisiting leptonic nonunitarity

Daniel Aloni, Avital Dery

In the presence of extra neutrino states at high scales, the low-energy effective $3 \times 3$ leptonic mixing matrix (LMM) is in general nonunitary. We revisit the question of what…

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…

CP violation in $b$ and $c$ quark decays

Avital Dery, Yuval Grossman, Stefan Schacht +1

Generically, non-Standard-Model particles contribute to processes with order-one charge-parity (CP) violating phases, as CP is not a fundamental symmetry of nature. The exploration…

New Physics Searches at Kaon and Hyperon Factories

Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61

Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…

$K \to μ^{+} μ^{-}$ beyond the standard model

Avital Dery, Mitrajyoti Ghosh

We analyze the New Physics sensitivity of a recently proposed method to measure the CP-violating $B (K_{S} \to μ^{+} μ^{-})_{ℓ = 0}$ decay rate using $K_{S} - K_{L}$ interference. We pre…

$K \to μ^{+} μ^{-}$ as a clean probe of short-distance physics

Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +1

The $K \to μ^{+} μ^{-}$ decay is often considered to be uninformative of fundamental theory parameters since the decay is polluted by long-distance hadronic effects. We demonstrate that,…

Probing the $Δ U = 0$ Rule in Three Body Charm Decays

Avital Dery, Yuval Grossman, Stefan Schacht +1

CP violation in charm decay was observed in the decays $D^{0} \to P^{\pm} P^{\mp}$ of a $D^{0}$ meson to two pseudoscalars. When interpreted within the SM, the results imply that…

SU(3) $_{F}$ Analysis for Beauty Baryon Decays

Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +1

We perform a general SU(3) $_{F}$ analysis of $b \to c c ˉ s (d)$ decays of members of the beauty baryon antitriplet to a member of the light baryon octet and a singlet. Under…

Implications of the LHCb discovery of CP violation in charm decays

Avital Dery, Yosef Nir

The recent measurement of $Δ A_{C P}$ by the LHCb collaboration requires an $O (10)$ enhancement coming from hadronic physics in order to be explained within the SM. We examine…

Dark Matter in Very Supersymmetric Dark Sectors

Avital Dery, Jeff A. Dror, Laurel Stephenson Haskins +2

If supersymmetry exists at any scale, regardless of whether it is restored around the weak scale, it may be a good symmetry of the dark sector, enforcing a degeneracy between its l…

Large Higgs-electron Yukawa coupling in 2HDM

Avital Dery, Claudia Frugiuele, Yosef Nir

The present upper bound on $κ_{e}$ , the ratio between the electron Yukawa coupling and its Standard Model value, is of $O (600)$ . We ask what would be the implications in case…

Testing Minimal Flavor Violation in Leptoquark Models of the $R_{K^{(*)}}$ Anomaly

Daniel Aloni, Avital Dery, Claudia Frugiuele +1

The $R_{K^{(*)}}$ anomaly can be explained by tree level exchange of leptoquarks. We study the consequences of subjecting these models to the principle of minimal flavor violation…

We embed Two Higgs Doublet Models (2HDMs) in the Froggatt Nielsen (FN) framework. We find that the approximate FN symmetry predicts i) approximate Natural Flavor Conservation (NFC)…

On a possible large width 750 GeV diphoton resonance at ATLAS and CMS

The ATLAS and CMS experiments at the LHC have reported an excess of diphoton events with invariant mass around 750 GeV, with local significance of about $3.6 σ$ and $2.6 σ$ , respec…

Model building for flavor changing Higgs couplings

Avital Dery, Aielet Efrati, Yosef Nir +2

If $t \to h q$ ( $q = c, u$ ) or $h \to τ ℓ$ ( $ℓ = μ, e$ ) decays are observed, it will be a clear signal of new physics. We investigate whether natural and viable flavor m…

Asymmetric lepton-flavor violating Higgs decays

Shikma Bressler, Avital Dery, Aielet Efrati

We introduce a new method to search for the lepton-flavor violating Higgs decays $h \to τ μ$ and $h \to τ e$ in the leptonic $τ$ decay channel. In particular, the Standar…

Measurements of the Yukawa couplings of the recently discovered boson h to fermion pairs will provide a new arena for studying flavor physics. We analyze the lessons that can be le…
