This paper proposes an improved Two Higgs Doublet Model derived from six-dimensional gauge theory compactified on an orbifold, where the inclusion of brane-localized gauge kinetic terms naturally enforces CP conservation and symmetry at tree level while allowing for the generation of soft symmetry-breaking masses and the Standard Model Higgs mass at the one-loop level.
This paper investigates the sensitivity of Higgs-gauge boson couplings at future lepton colliders by simulating the process within the SMEFT framework, ultimately deriving stringent 95% C.L. limits on the and coefficients for 3 TeV CLIC and 10 TeV Muon Collider scenarios that significantly surpass current experimental bounds.
This paper employs nonperturbative Hamiltonian theory with two-particle coupled channels to extract physical electric dipole amplitudes from recent lattice QCD data on threshold pion electroproduction, while deriving a new expression for transition amplitudes that depends solely on final-state interactions.
This paper demonstrates that different, formally equivalent resummation prescriptions for the thrust distribution in annihilation yield non-negligible numerical differences that exceed standard theoretical uncertainties, thereby necessitating more conservative error estimates in strong coupling determinations.
This paper computes the complete set of leading-twist gluon and sea-quark generalized transverse momentum distributions (GTMDs) in the small- eikonal approximation at vanishing skewness, establishing universal relations among them and projecting the results onto transverse momentum dependent distributions (TMDs) and generalized parton distributions (GPDs) to guide phenomenological modeling and enable explicit calculations.
This paper presents the first next-to-next-to-leading order (NNLO) QCD event generation for production matched to parton showers using the MiNNLOPS method, which incorporates a novel pointwise combination of soft and high-energy two-loop amplitude approximations to provide robust, publicly available predictions for Higgs-boson decay into photons with off-shell top-quark decays.
This paper presents precise calculations for the production cross-section and invariant mass distribution at the LHC by improving both quark- and gluon-initiated subprocesses through leading and sub-leading soft gluon threshold resummation within the QCD framework.
This paper investigates the lightest and second-lightest Higgs bosons within a CP-violating next-to-minimal B-L supersymmetric model (NB-LSSM), demonstrating how CP-violating phases and specific parameters induce significant mixing in the Higgs sector to successfully fit both the 125 GeV SM-like Higgs data and the hypothetical 95 GeV excess.
This paper presents a third-order QCD analysis of threshold resummation for Drell-Yan type colorless processes at the LHC, demonstrating that matching NLL resummation with NLO fixed-order results significantly reduces theoretical scale uncertainties from approximately 0.4% to below 0.1% in the high invariant mass region.
This paper presents the updated 2025 Physics Briefing Book for the Latin American Strategy Forum for Research Infrastructure in High Energy, Cosmology, and Astroparticle Physics (LASF4RI-HECAP), which synthesizes 46 community white papers and symposium discussions to establish a long-term strategic roadmap across seven key scientific and technical working groups.
This paper investigates the unitarity violation scale of a non-minimally coupled scalar field with quartic self-coupling by calculating six-point scattering amplitudes in both Jordan and Einstein frames, explicitly demonstrating their frame-independence and showing that the dominant contribution arises from the scalar potential.
This paper presents a study of second-order QCD corrections for the decay of a pseudoscalar Higgs boson into three partons within an effective theory framework, providing essential results for predicting differential distributions of the Higgs boson in association with jets at hadron colliders.
This paper presents threshold-resummed predictions for vector boson pair (WW and ZZ) production at the LHC at NNLO+NNLL accuracy, demonstrating that the inclusion of resummed corrections reduces scale uncertainties and adds a few percent to the fixed-order results.
This paper develops new analytic fitting formulae for photodisintegration cross sections to demonstrate that the survival of ultraheavy nuclei in protomagnetar outflows is highly sensitive to the outflow geometry and engine properties, with spherical winds allowing survival only in the early phase and jetted outflows permitting survival primarily in low-spin-down energy scenarios before jet breakout.
This paper presents a numerically efficient method for evaluating a two-loop contribution to the dark-matter trispectrum by expanding around a fixed reference cosmology, achieving sub-percent accuracy with only third-order terms and offering a practical pathway for faster computations of higher-order correlators in the Effective Field Theory of Large-Scale Structure.
This paper introduces the KKMChh program, which extends the soft photon exponentiation of KKMC to hadron collisions by developing the NISR algorithm to consistently interface with parton showers and QED-inclusive parton distribution functions, along with presenting results on its phenomenological impact.
This paper critiques a 2025 study by Ballardini et al. for incorrectly calculating third-order slow-roll corrections due to improper integration techniques, demonstrating through numerical Monte-Carlo methods that the original exact analytical results by Auclair and Ringeval remain valid.
This paper develops a fully field-theoretic effective description of photon condensation in a hadronic cavity by deriving analytic criteria for condensation and mapping the reduced dynamics to standard nonlinear quantum-optics Hamiltonians, thereby bridging finite-density hadronic physics with experimental cavity diagnostics.
This paper presents a new recursive algorithm designed to numerically reduce arbitrary two-loop tensor integrals to scalar integrals, serving as a key component for developing automated next-to-next-to-leading order tools required for high-precision collider physics.
This paper presents the calculation of the previously missing corrections to the quantity involving one closed fermion loop, which significantly increases the Standard Model prediction for the W-boson mass by over 3 MeV.
