Weak charge and weak radius of C

Oleksandr Koshchii, Jens Erler, Mikhail Gorchtein +5

We present a feasibility study of a simultaneous sub-percent extraction of the weak charge and the weak radius of the C nucleus using parity-violating electron scattering,…

First-principles calculation of electroweak box diagrams from lattice QCD

Xu Feng, Mikhail Gorchtein, Lu-Chang Jin +2

We present the first realistic lattice QCD calculation of the -box diagrams relevant for beta decays. The nonperturbative low-momentum integral of the loop is calculated u…

Joint lattice QCD - dispersion theory analysis confirms the quark-mixing top-row unitarity deficit

Chien-Yeah Seng, Xu Feng, Mikhail Gorchtein +1

Recently, the first ever lattice computation of the -box radiative correction to the rate of the semileptonic pion decay allowed for a reduction of the theory uncertainty of th…

Contraction Diagram Analysis in Pion-Kaon Scattering

Chaitra Kalmahalli Guruswamy, Ulf-G. Meißner, Chien-Yeah Seng

We study the contributions from the connected and disconnected contraction diagrams to the pion-kaon scattering amplitude within the framework of SU partially-quenched chira…

A New Theory Framework for the Electroweak Radiative Corrections in Decays

Chien-Yeah Seng, Daniel Galviz, Ulf-G. Meißner

We propose a new theory framework to study the electroweak radiative corrections in decays by combining the classic current algebra approach with the modern effective fiel…

Reduced uncertainty of the axial -box correction to the proton's weak charge

Jens Erler, Mikhail Gorchtein, Oleksandr Koshchii +2

We present the fully up-to-date calculation of the -box correction which needs to be taken into account to determine the weak mixing angle at low energies from parity-violating…
