This paper demonstrates that a Convolutional Neural Network can conceptually characterize two-component Dark Matter signals at the LHC by inferring the presence, mass, and spin (0 or 1/2) of the particles from mono-jet and mono-Z probes, although the study does not include a signal-to-background analysis.
This paper demonstrates that a novel first-order action functional consistently incorporates gravity and matter fields, offering a robust new pathway toward the unification of fundamental interactions within a more fundamental theory of General Relativity and the Standard Model.
This paper revisits the minimal Nelson-Barr model to demonstrate that imposing an additional approximate global symmetry resolves the quality problem, while also proposing a solution to the domain wall problem and validating the viability of thermal leptogenesis.
By leveraging recent theoretical advancements regarding the "memory burden" effect that halts the evaporation of light primordial black holes, this study establishes new and tighter upper limits on the primordial curvature power spectrum within the previously underexplored small-scale range of to .
Motivated by recent experimental advancements, this paper systematically investigates light and charm meson M1 radiative transitions by calculating effective transition magnetic moments and decay widths using an effective mass scheme and a non-relativistic potential model, while highlighting the decisive role of higher-order QCD corrections and scale-dependent effects.
This paper constructs a comprehensive atlas of simple gauge theories with massless fermions based on ab-initio assumptions, utilizing a degree-of-freedom counting method to identify the SU(5) Georgi-Glashow model as the minimal Grand-unification Theory for three matter generations and to map out viable extensions of the Standard Model.
Using the quark-meson coupling model with in-medium loop contributions, this study predicts significant mass reductions of approximately 60 MeV for -wave charmonia () in cold nuclear matter at normal density, while finding no level crossing with the threshold up to three times normal density, a phenomenon potentially observable at FAIR and RHIC.
This paper investigates the gradient property of renormalization group flows in scalar-fermion quantum field theories up to four-loop order, demonstrating that the beta shift is essential for satisfying over a thousand scheme-independent gradient conditions and that conformal field theories with non-zero beta shifts dominate the theory space as the number of fields increases.
This paper introduces an amortized inference method using likelihood-weighted normalizing flows that overcomes the limitations of standard unimodal base distributions by initializing with a Gaussian Mixture Model, thereby accurately capturing multi-modal, non-Gaussian posteriors in high-dimensional inverse problems as demonstrated in multi-modal benchmarks and a heavy flavor physics application.
This paper employs a worldline effective field theory to develop a systematic framework for binary black holes with bosonic clouds on generic eccentric and inclined orbits, revealing how resonant and non-resonant interactions drive unique orbital evolutions like floating orbits and inclination-dependent fixed points that produce distinctive gravitational-wave signatures for future detectors.
