The correction to superallowed beta decays in effective field theory and implications for
Zehua Cao, Richard J. Hill, Ryan Plestid +1
Superallowed () beta decays currently provide the most precise extraction of quark mixing in the Standard Model. Their interpretation as a measurement of $|V_{ud…
Factorization and resummation of QED radiative corrections for neutron beta decay
Zehua Cao, Richard J. Hill, Ryan Plestid +1
Details of the two-loop analysis of long-distance QED radiative corrections to neutron beta decay are presented. Explicit expressions are given for hard, jet, and soft functions ap…
The Fermi function and the neutron's lifetime
Peter Vander Griend, Zehua Cao, Richard Hill +1
The traditional Fermi function ansatz for nuclear beta decay describes enhanced perturbative effects in the limit of large nuclear charge and/or small electron velocity . We…
Renormalization of beta decay at three loops and beyond
Kaushik Borah, Richard J. Hill, Ryan Plestid
The anomalous dimension for heavy-heavy-light effective theory operators describing nuclear beta decay is computed through three-loop order in the static limit. The result at order…
Searching for new physics at facilities with and decays at rest
Richard J. Hill, Ryan Plestid, Jure Zupan
We investigate the ability of facilities, Mu2e and COMET, to probe, or discover, new physics with their detector validation datasets. The validation of the detecto…
All orders factorization and the Coulomb problem
Richard J. Hill, Ryan Plestid
In the limit of large nuclear charge, , or small lepton velocity, , Coulomb corrections to nuclear beta decay and related processes are enhanced as and becom…
Field Theory of the Fermi Function
Richard J. Hill, Ryan Plestid
The Fermi function accounts for QED corrections to beta decays that are enhanced at either small electron velocity or large nuclear charge . For precision applicati…
NuSTEC White Paper: Status and Challenges of Neutrino-Nucleus Scattering
L. Alvarez-Ruso, M. Sajjad Athar, M. B. Barbaro +22
The precise measurement of neutrino properties is among the highest priorities in fundamental particle physics, involving many experiments worldwide. Since the experiments rely on…
Factorization and Sudakov Resummation in Leptonic Radiative B Decay
S. W. Bosch, R. J. Hill, B. O. Lange +1
Soft-collinear effective theory is used to prove factorization of the B->gamma+l+nu decay amplitude at leading power in Lambda/m_b, including a demonstration of the absence of non-…
New Value of M_mu/M_e from Muonium Hyperfine Splitting
Richard Hill
The complete contribution to the muonium hyperfine splitting of relative order alpha^3(m_e/m_mu)ln(alpha) is calculated. The result amounts to 0.013 kHZ, much smaller than suggeste…
