Log Gaussian Cox Process Background Modeling in High Energy Physics

This paper introduces a novel Log Gaussian Cox Process (LGCP) method for modeling smooth backgrounds in high energy physics that minimizes assumptions about the underlying shape by utilizing a Gaussian process for the intensity function and Markov Chain Monte Carlo for optimization, demonstrating its effectiveness through synthetic experiments against traditional analytic functional forms.

Implications of Flavor Symmetries for Baryon Number Violation

This paper systematically classifies dimension-six baryon-number-violating SMEFT operators under various flavor-symmetry assumptions, demonstrating how their interplay with neutrino masses can allow for multi-TeV BNV scales consistent with proton decay constraints, while also identifying UV completions where the effective field theory description may be insufficient.

Laser-assisted production of the light charged Higgs boson from top quark decay in the type-I two Higgs doublet model

This paper investigates the impact of a circularly polarized laser field on top quark decay within the type-I two Higgs doublet model, demonstrating that specific laser parameters can significantly enhance the branching ratio of the tbH+t \rightarrow bH^+ channel to 0.97, thereby surpassing the standard tbW+t \rightarrow bW^+ decay and offering a promising strategy for detecting charged Higgs bosons.

Origin of the Covariant Wigner Operator as a Quantum Amplitude in QCD

This paper extends the Koopman-von Neumann-Sudarshan Hilbert space formulation to relativistic QCD, demonstrating that the covariant Wigner operator is fundamentally a quantum probability amplitude projected onto phase space, thereby offering a unified framework that clarifies the origin of nonclassical features like negativity and establishes a transparent foundation for parton distribution functions.

Descending into the Modular Bootstrap

This paper employs machine-learning-style optimization, featuring a novel singular-value-based optimizer and uncertainty estimation, to numerically explore the landscape of two-dimensional conformal field theories with central charges between 1 and 8/7, identifying candidate spectra in a previously uncharted region and suggesting a tighter constraint on the spectral gap near c=1c=1.
