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

Nejc Košnik, Zachary Polonsky, Aleks Smolkovič

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

The Standard Model Prediction for the Rare Decay

Matteo Fael, Jack Jenkins, Enrico Lunghi +1

We present updated and comprehensive Standard Model predictions for the inclusive rare decay . Using a state-of-the-art determination of the short-distance coeffi…

Charm rescattering in : an improved analysis

Gino Isidori, Zachary Polonsky, Arianna Tinari

We improve upon previous explicit estimates of charm rescattering contributions to the decay by including contributions from dipole interactions with the…

Explicit estimate of charm rescattering in

Gino Isidori, Zachary Polonsky, Arianna Tinari

We analyze long-distance contributions induced by the rescattering of a pair of charmed and charmed-strange mesons. We present an explicit estimate of…

A Simple Dirac Prescription for Two-Loop Anomalous Dimension Matrices

Jason Aebischer, Marko Pesut, Zachary Polonsky

A novel method to treat effects from evanescent operators in next-to-leading order (NLO) computations is introduced. The approach allows, besides further simplifications, to discar…

Renormalization scheme factorization of one-loop Fierz identities

Jason Aebischer, Marko Pesut, Zachary Polonsky

We present a proof of the factorization of renormalization scheme in one-loop-corrected Fierz identities. This scheme factorization facilitates the simultaneous transformation of o…

A Precise Electron EDM Constraint on CP-odd Heavy-Quark Yukawas

Joachim Brod, Zachary Polonsky, Emmanuel Stamou

CP-odd Higgs couplings to bottom and charm quarks arise in many extensions of the standard model and are of potential interest for electroweak baryogenesis. These couplings induce…

Semi-inclusive transitions at high

Gino Isidori, Zachary Polonsky, Arianna Tinari

We present an updated Standard Model (SM) estimate of the inclusive rate at high dilepton invariant mass (). We show that this estima…

Dipole operators in Fierz identities

Jason Aebischer, Marko Pesut, Zachary Polonsky

We study the contribution from dipole operators to one-loop Fierz identities and provide the resulting QCD and QED shifts to the tree-level relations for all four-fermion operators…

Electroweak Corrections to the Charm-Top-Quark Contribution to

Joachim Brod, Sandra Kvedaraite, Zachary Polonsky +1

We calculate the leading-logarithmic and next-to-leading-logarithmic electroweak corrections to the charm-top-quark contribution to the effective Lagrangian, relevant fo…

Two-loop Electroweak Corrections to the Top-Quark Contribution to

Joachim Brod, Sandra Kvedaraitė, Zachary Polonsky

The parameter measures violation in the neutral kaon system. It is a sensitive probe of new physics and plays a prominent role in the global fit of the Cabibbo-Kobabyash…

Two-loop Beta Function for Complex Scalar Electroweak Multiplets

Joachim Brod, Zachary Polonsky

We present the general form of the renormalizable four-point interactions of a complex scalar field furnishing an irreducible representation of SU(2), and derive a set of algebraic…

Holographic Entanglement Entropy and the (3+1)-dimensional Topological Black Hole

Zachary Polonsky, Alex Flournoy

We investigate the Holographic Entanglement Entropy proposal in the context of the (3+1)-dimensional topological black hole. In contrast to the well-studied (2+1)-dimensional case,…

Thermodynamic phase transitions from dynamical compact dimensions

Zachary Polonsky, Alex Flournoy

We perform a double quotient of global AdS and study its thermal properties. We find that a double quotient yields a spacetime with an expanding compact dimension. Studying the…
