Current and future constraints on heavy New Physics from $I ¨ $ weak dipole moments

Nejc KoÅ¡nik, Zachary Polonsky, Aleks SmolkoviÄ

We study the weak magnetic and electric dipole moments of the $I ¨ $ lepton as precision tests of the Standard Model (SM) and probes of heavy New Physics (NP). We present an updated…

The Standard Model Prediction for the Rare Decay $B \to X_{s} I^½ I^ˉ ½$

Matteo Fael, Jack Jenkins, Enrico Lunghi +1

We present updated and comprehensive Standard Model predictions for the inclusive rare decay $B \to X_{s} I^½ I^ˉ ½$ . Using a state-of-the-art determination of the short-distance coef…

Charm rescattering in $B^{0} \to K^{0} ℓ ˉ ℓ$ : an improved analysis

Gino Isidori, Zachary Polonsky, Arianna Tinari

We improve upon previous explicit estimates of charm rescattering contributions to the decay $B^{0} \to K^{0} ℓ ˉ ℓ$ by including contributions from dipole interactions with the…

Time-Dependent Precision Measurement of $B_{s}^{0} \to I ¨ I^¼^{+} I^¼^{-}$ Decay at FCC- $ee$

Tsz Hong Kwok, Zachary Polonsky, Valeriia Lukashenko +2

We study the feasibility of measuring time-dependent $C P$ violation in the rare flavor-changing neutral current (FCNC) decay $B_{s}^{0} \to I ¨ (\to K^{+} K^{-}) I^¼^{+} I^¼^{-}$ …

Explicit estimate of charm rescattering in $B^{0} \to K^{0} ℓ ˉ ℓ$

Gino Isidori, Zachary Polonsky, Arianna Tinari

We analyze $B^{0} \to K^{0} ℓ ˉ ℓ$ long-distance contributions induced by the rescattering of a pair of charmed and charmed-strange mesons. We present an explicit estimate of…
