This paper reviews Permutation Invariant Gaussian Matrix Models (PIGMM), which leverage symmetry to simplify complex -variable matrix data analysis into a tractable 13-parameter framework, demonstrating successful applications in fields ranging from computational linguistics to finance and neural networks while proposing future uses in collider physics.
This paper reviews the development and construction challenges of major high-energy neutrino and cosmic ray detectors, specifically DUMAND, Lake Baikal, IceCube, and the Auger Observatory, between 1980 and 2000, highlighting how controversial 1980s claims of PeV gamma-rays from Cygnus X-3 influenced their advancement.
This study employs a Bayesian analysis of charged-particle nuclear modification factors across four collision systems (O+O, Ne+Ne, Xe+Xe, and Pb+Pb) to determine that parton energy loss in the quark-gluon plasma scales with an effective path-length exponent of , decisively favoring a radiative mechanism over collisional or strong-coupling scenarios and confirming a universal energy-loss regime from small to large systems.
This paper investigates the early thermal evolution of newborn strange stars in two-flavor (2SC) and color-flavor-locked (CFL) color superconducting phases, demonstrating that while Schwinger pair luminosity is a universal function of temperature independent of the quark phase, neutrino emission generally dominates cooling except in the CFL phase with a large gap parameter where pair luminosity becomes comparable.
This study projects the sensitivity of the 100 TeV FCC-hh to anomalous quartic gauge couplings via production in the channel, demonstrating that a deep neural network analysis with realistic detector simulation can achieve order-of-magnitude improvements over current LHC limits on specific coupling parameters.
This paper demonstrates that a future multi-TeV muon collider offers unprecedented sensitivity to charged lepton-flavor-violating four-lepton operators within the Standard Model Effective Field Theory, with projected constraints on Wilson coefficients reaching up to an order of magnitude beyond current limits through global fits of angular distributions at various center-of-mass energies and beam polarizations.
This paper presents a concise method for analyzing the stability and electroweak symmetry breaking conditions of the general Two-Higgs-Doublet Model, demonstrating its utility by recovering known results for the MSSM and clarifying the properties of the Gunion et al. potential.
This paper proposes that a coherent axion field from the local dark matter halo couples to hard virtual gluons in hadron collisions, thereby shifting the boson mass measurement and explaining the discrepancy between the CDF and CMS experimental results as a new phenomenon beyond the Standard Model.
This paper utilizes an effective theory of center vortices to demonstrate the area law fall-off and derive the string tension for SU(2) gauge theory in three-dimensional Euclidean space-time, revealing that the repulsive force between vortices increases with temperature to facilitate the deconfinement regime.
This paper proposes using precise, time-resolved spectroscopy of S-stars orbiting the supermassive black hole Sgr A* to detect coherent temporal oscillations of the fine-structure constant induced by ultralight scalar fields, thereby enabling stringent constraints on scalar-photon couplings within the Galactic Center's high-density environment.
