Gennari M, Drissi M, Gorchtein M, Navratil P, Seng C
Phys Rev Lett . 2025 Feb; 134(1):012501. PMID: 39913724
We report the first ab initio calculation of the nuclear-structure-dependent radiative correction δ_{NS} to the ^{10}C→^{10}B superallowed transition, computed with the no-core shell model and chiral effective field theory. We...

Ma P, Feng X, Gorchtein M, Jin L, Liu K, Seng C, et al.
Phys Rev Lett . 2024 May; 132(19):191901. PMID: 38804936
We present the first lattice QCD calculation of the universal axial γW-box contribution □_{γW}^{VA} to both superallowed nuclear and neutron beta decays. This contribution emerges as a significant component within...

Feng X, Gorchtein M, Jin L, Ma P, Seng C
Phys Rev Lett . 2020 May; 124(19):192002. PMID: 32469584
We present the first realistic lattice QCD calculation of the γW-box diagrams relevant for beta decays. The nonperturbative low-momentum integral of the γW loop is calculated using a lattice QCD...

Gorchtein M
Phys Rev Lett . 2019 Sep; 123(4):042503. PMID: 31491248
I consider the γW-box correction to superallowed nuclear β decays in the framework of dispersion relations. I address a novel effect of a distortion of the emitted electron energy spectrum...

Seng C, Gorchtein M, Patel H, Ramsey-Musolf M
Phys Rev Lett . 2019 Jan; 121(24):241804. PMID: 30608731
We analyze the universal radiative correction Δ_{R}^{V} to neutron and superallowed nuclear β decay by expressing the hadronic γW-box contribution in terms of a dispersion relation, which we identify as...

Gorchtein M
Phys Rev Lett . 2015 Dec; 115(22):222503. PMID: 26650300
The well-known Levinger-Bethe photonuclear sum rule relates the strength of the photoexcitation of the giant dipole resonance in a nucleus to the number of nucleons in that nucleus. I extend...

Gorchtein M, Szczepaniak A
Phys Rev Lett . 2008 Oct; 101(14):141601. PMID: 18851518
We formulate the low-energy theorem for virtual Compton scattering off a nucleon and examine its consequences for generalized nucleon polarizabilites. As a result of a new, model-independent definition of the...
