This paper introduces a universal algorithm called anyPUB that systematically derives perturbative unitarity bounds for any particle physics model by computing high-energy $2 \rightarrow 2$ scattering matrices, a method validated against existing literature and applied to derive new constraints for the minimal left-right symmetric and Pati-Salam models.
This paper extends the gradient-expansion formalism to massive vector fields to model their non-linear production during inflation via inflaton couplings, demonstrating that while pure mass coupling enhances only longitudinal modes, the inclusion of kinetic coupling allows transverse modes to dominate or drives the system into a strong backreaction regime depending on the coupling function's behavior.
This paper investigates the discovery potential of a scalar leptoquark doublet coupling to light quarks and right-handed neutrinos at a muon collider, demonstrating that indirect probes and direct production channels (both pair and single) offer robust sensitivity to masses up to 7 TeV, significantly surpassing the projected capabilities of the High-Luminosity LHC.
This paper presents the first complete next-to-leading-order calculation of BFKL impact factors for the hadroproduction of specific NRQCD quarkonium states by combining virtual corrections with real-emission contributions, demonstrating the cancellation of soft divergences and the compatibility of surviving collinear singularities with factorization to enable future next-to-leading-logarithmic precision studies.
This paper improves theoretical predictions for rare -boson decays into heavy vector quarkonium and lepton pairs by including all relevant Standard Model tree-level diagrams, revealing that while fragmentation dominates charmonium channels, additional diagrams increase bottomonium branching fractions by 4–9%, and confirming that forward-backward asymmetries vanish in the Standard Model to provide a baseline for future experimental tests.

This paper introduces a path integral-based method to directly compute reduced density matrices in open quantum systems, applying it to a scalar field model and a neutrino toy model to demonstrate how initial Fock state correlations and lighter neutrino masses lead to significant distortions in particle number probabilities due to environmental interactions.
This paper demonstrates that a minimally extended Georgi-Machacek model can naturally explain the observed LHC and LEP excesses at 95 GeV and 152 GeV through specific features like light scalar masses and enhanced diphoton decays, while predicting additional light scalars and offering promising prospects for future discovery at the HL-LHC and colliders.
This paper presents updated constraints on the total neutrino mass and its hierarchy across various cosmological models using ACT DR6, DESI DR2, and DESY5 data, revealing that while dark energy evolution significantly influences the tightness of upper limits, the inverted hierarchy consistently yields weaker constraints than the degenerate hierarchy.
The paper introduces NuFast-Earth, a fast, flexible, and accurate C++ algorithm designed to efficiently compute neutrino oscillation probabilities for atmospheric, nighttime solar, and supernova neutrinos traversing the Earth's varying density profiles, thereby addressing the growing computational demands of next-generation neutrino experiments.
This paper demonstrates that within the most general formulation of gravity with independent metric and connection, a unique naturally light vector or scalar distortion field emerges as a dynamical degree of freedom, notably predicting a light scalar particle that mixes with the Higgs boson.

This paper systematically investigates the spectroscopic and decay properties of four triply heavy-flavor tetraquark systems using a nonrelativistic quark model, predicting compact ground-state masses between 5.2–5.5 GeV and 15.0–15.3 GeV that are unstable against strong rearrangement decays, while identifying specific narrow resonances and proposing experimental search channels in , , and modes.
