This paper investigates third-generation flavor-violating transitions mediated by bosons within the SMEFT framework, utilizing the optimal observable technique to project the Future Circular Collider's (FCC-ee) sensitivity across various energy stages and demonstrating its potential to provide complementary and direct probes of flavor physics alongside low-energy constraints.
This paper proposes a renormalizable, anomaly-free axial model where muon and tau masses arise via a universal seesaw mechanism, and systematically analyzes its experimental signatures and constraints across the MeV to TeV mass range, highlighting distinct phenomenological features such as axial weak coefficient modifications in neutrino trident production and chirality-sensitive angular distributions at future muon colliders.
This paper presents a quantum algorithmic framework utilizing maximal-tree gauge fixing and quantum singular value transformation to efficiently simulate non-Abelian Yang-Mills theories, including QCD, with proven polynomial scaling in system parameters and simulation precision.
This paper serves as an opening keynote lecture for the 4th International Symposium on the History of Particle Physics, surveying the field's development from the prehistory of the discovery through the early 1980s to provide context for the symposium's subsequent presentations.
This paper introduces Masked Particle Modeling (MPM), a self-supervised pre-training framework that learns permutation-invariant representations of unordered particle sets in high energy physics by reconstructing masked particles via vector quantization, demonstrating its effectiveness as a foundation model for diverse downstream tasks like jet classification and domain transfer.
This paper demonstrates that the Classification Without Labels (CWoLa) paradigm can eliminate the need for background simulation in high energy physics, enabling the training of supervised classifiers that achieve higher performance on real data by avoiding the domain shift caused by inaccuracies in low-level feature simulations.
This paper proposes that the gravothermal core collapse of self-interacting dark matter halos, aided by baryonic accretion, can rapidly seed and grow supermassive black holes to the masses observed in JWST's "little red dots" at high redshifts within approximately 500 million years.
This paper proposes a theoretical framework where tetrahedron rotational symmetry unifies sequential and non-sequential gauge theories, interpreting sequential terms as higher-order corrections to non-sequential leading terms to explain quark and lepton mixing patterns without requiring supersymmetry.
This paper derives closed-form one-loop Euler-Heisenberg effective actions for Dirac fermions in combined electromagnetic and massive axial vector backgrounds by diagonalizing the functional Hessian to classify stability sectors, revealing novel nonperturbative pair-production rates with vacuum stabilization, dynamical chiral symmetry breaking, and potential applications ranging from baryogenesis to condensed matter physics.
This paper proposes a unified multimessenger search strategy for composite dark matter that combines updated white dwarf constraints with novel gravitational wave detection prospects, demonstrating that future detectors like LISA, TianQin, and Taiji can probe previously inaccessible regions of the dark matter parameter space.
