    Neutrinoless Double-Beta Decay by Andrea Giuliani, Alfredo Poves

    Published 2012-01-01
    “…Implications of this phenomenon on crucial aspects of particle physics are briefly discussed. The calculations of the nuclear matrix elements in case of mass mechanisms are reviewed, and a range for these quantities is proposed for the most appealing candidates. …”

    Current-Component Independent Transition Form Factors for Semileptonic and Rare D⟶πK Decays in the Light-Front Quark Model by Ho-Meoyng Choi

    Published 2021-01-01
    “…The form factors are obtained in the q+=0 frame and then analytically continue to the physical timelike region. Together with our recent analysis of the current-component independent form factors f±q2 for the semileptonic decays, we present the current-component independent tensor form factor fTq2 for the rare decays to make the complete set of hadronic matrix elements regulating the semileptonic and rare D⟶πK decays in our LFQM. …”

    Scattering from an external field in quantum chromodynamics at high energies: From foundations to interdisciplinary connections by Athanasia-Konstantina Angelopoulou, Anh Dung Le, Stéphane Munier

    Published 2025-03-01
    “…We review the factorization of the $S$-matrix elements in the context of particle scattering off an external field, which can serve as a model for the field of a large nucleus. …”

    D-Brane effective Lagrangian in spacetimes with boundaries by Ali Baradaran-Hosseini, Mohammad R. Garousi

    Published 2024-10-01
    “…Two of these parameters are physical and are determined by disk-level S-matrix elements, while the third is unphysical and can be eliminated by field redefinitions and integration by parts. …”
