This paper presents CaloScore v2, an improved diffusion-based model for fast calorimeter shower simulation that utilizes progressive distillation to achieve high-fidelity sample generation with a single function evaluation, thereby overcoming the computational bottlenecks of traditional diffusion processes.
This paper introduces SBUnfold, a novel generative unfolding method leveraging Schrödinger Bridges and diffusion models to combine the strengths of discriminative and generative approaches, enabling efficient, high-dimensional cross-section measurements without relying on known probability densities.
This paper demonstrates how a new Foundation Model for hadronic jets addresses three critical challenges in collider physics—reducing computational costs for reconstruction, enabling comprehensive uncertainty quantification, and facilitating model-agnostic new physics searches—thereby transitioning jet-based Foundation Models from proof-of-concept studies to practical tools for researchers.
The paper investigates the Brout-Englert-Higgs mechanism prior to symmetry breaking and demonstrates that the interaction between Higgs fields and massless gauge fields results in the production of particles with negative squared mass.
The paper introduces "OmniLearn," a jet-physics foundation model that leverages a representation learned from a specific multiclass generation and classification task to simultaneously enhance the accuracy, precision, and speed of diverse downstream jet physics tasks across different datasets, collision systems, and analysis goals.
This paper comprehensively updates experimental constraints on flavor-violating boson couplings to charged leptons by analyzing a wide range of direct and indirect bounds from current data and provides projections for future improvements from experiments like FCC-ee, Belle II, and Mu2e.
This paper employs a quantum field theory framework with virtual Majorana neutrinos to derive exact dressed propagators in a magnetic field, demonstrating that the resulting spin-flavor precession probability aligns with standard quantum mechanical predictions while revealing small quantum corrections.
This paper presents CoMBolt-ITA, a new (2+2)D collective model based on the relativistic Boltzmann equation in the isotropization time approximation that successfully couples pre-equilibrium dynamics with hydrodynamics to simulate quark-gluon plasma evolution, demonstrating strong consistency with standard hydrodynamic and hybrid models for small shear viscosity while revealing significant discrepancies and nontrivial thermalization effects for larger viscosity values.
This paper establishes the bounded-from-below and vacuum stability conditions for the scalar potential of the Standard Model extended by a scalar multiplet with dimension (ranging from 1 to 6), null vacuum expectation value, and arbitrary hypercharge, while also characterizing the resulting phase space geometry.
This paper proposes that future high-frequency gravitational wave experiments can detect unique signatures generated during the freeze-in production of dark matter from heavy particle decay, offering a novel method to test this paradigm beyond the reach of current direct detection experiments.
