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…
