This paper presents the first computation of the subleading twist correction from the three-particle -meson distribution amplitude at next-to-leading order using soft-collinear effective theory, thereby completing the leading-power factorization analysis and enabling improved field-theoretic predictions for electroweak penguin decays.
This paper establishes the factorization framework for scattering processes near partonic threshold at next-to-leading power by defining gauge-invariant jet functions, verifying the resulting formula at one and two loops for the massive electromagnetic form factor, and identifying endpoint divergences and the extension to multi-gluon emissions as the remaining challenges for systematic resummation.
This paper computes the one-loop effects of vector-like fermions on the Higgs-strahlung cross-section at FCC-ee, finding that while mixing-driven scenarios are already constrained by existing data, Yukawa-driven scenarios offer a promising radiative probe where significant parameter space allowed by LHC searches could produce detectable deviations at the per-mille sensitivity level.
This paper presents a simple algorithm integrated into the KKMC Monte Carlo generator to calculate event weights for simulating events with anomalous electric and magnetic dipole moments, demonstrating their impact on spin correlations and cross sections through specific decay distributions at 10.58 GeV.
This paper presents a machine learning-based b-jet tagging method using a convolutional neural network trained on jet, track, and secondary vertex information for anti- jets in 13 TeV $pp$ collisions, demonstrating superior performance over traditional tagging techniques.
This paper proposes a method to significantly reduce the uncertainty in nuclear matrix elements for neutrinoless double-beta decay by utilizing a phenomenological effective axial-vector coupling derived from measured two-neutrino double-beta decay half-lives, thereby refining the constraints on the effective neutrino mass.
This paper resolves the long-standing issue of spurious gauge dependence in electroweak phase transition studies by rigorously establishing the gauge invariance of bubble nucleation rates up to two-loop order within a three-dimensional thermal effective field theory framework, thereby providing a robust theoretical foundation for precise predictions of gravitational waves, electroweak baryogenesis, and primordial magnetogenesis.
This paper presents the TauSpinner algorithm, which utilizes event reweighting techniques to incorporate anomalous New Physics effects, such as lepton dipole moments and CP-violating phase shifts, into the simulation of spin correlations and polarization in processes at the LHC.
This paper demonstrates that by applying the Nielsen identity and specific power-counting schemes within the three-dimensional Standard Model effective field theory, vacuum decay rates and phase transition parameters during the electroweak phase transition can be rendered gauge-invariant, thereby enabling more accurate predictions of gravitational wave signatures.
This paper proposes a testable framework for light fermion dark matter where a strongly first-order phase transition in a dark sector enables the correct relic abundance through kinematically forbidden or loop-suppressed annihilation channels, thereby naturally evading stringent CMB and indirect detection constraints while predicting associated gravitational waves.
