This paper proposes using normalized symmetric cumulants and Pearson coefficients derived from ultracentral Ne+Ne collisions at the LHC, combined with Brink model calculations and hydrodynamic simulations, to distinguish between competing Ne cluster configurations (5 versus +O) and probe nuclear structure transitions.
This paper presents a projected search for additional scalar bosons within the Inert Doublet Model at the FCC-ee, utilizing a parametric neural network to analyze final states with two leptons at 240 and 365 GeV, demonstrating the potential to exclude nearly the entire available parameter space and discover new scalars with masses up to 110 and 165 GeV respectively.
This paper demonstrates that in pure $SU(N)$ gauge theories, gluon polarization entanglement arises exclusively from opposite initial polarizations and reaches a universal maximum at a 90-degree scattering angle independent of the gauge group, provided the precise balance between three- and four-gluon vertices is maintained.
This paper demonstrates that neglecting the impact of electroweak symmetry breaking on particle masses and interactions during the thermal evolution of the Universe can lead to significant errors in calculating Dark Matter relic density within Higgs portal models, potentially resulting in the incorrect inclusion or exclusion of viable parameter space.
This paper investigates the sensitivity of a 3 TeV muon collider to the lepton-flavor couplings of doubly charged scalars with masses above 1 TeV, demonstrating high signal significance and proposing an angular distribution variable to distinguish them from neutral scalars.
This paper analyzes simulated LHC proton-proton collisions to identify the most active events (top 0.1%) using various estimators, concluding that flattenicity is the optimal tool for selecting these events with minimal bias on particle ratios and collision hardness.
This paper investigates the radiative and non-radiative orbital angular momentum (OAM) dynamics of relativistic vortex particles in accelerators, revealing that while OAM loss via photon emission is negligible, non-radiative precession induces resonances at lower energies than spin, thereby suggesting the use of linacs for acceleration and adapted Siberian snakes for OAM manipulation to enable high-energy collisions with enhanced magnetic moments.
This paper employs an open quantum system framework and numerical solutions of the Lindblad master equation to demonstrate that future nuclear spin experiments like CASPEr, while primarily designed for axion dark matter searches, could potentially constrain the cosmic neutrino background overdensity parameter to levels of –, thereby showcasing the promise of quantum sensing for probing fundamental physics.
This paper utilizes bootstrapped on-shell amplitudes to analyze gluon-fusion double and triple Higgs production, establishing a precise kinematic framework to distinguish between SMEFT and HEFT by identifying the specific operator dimensions and loop orders at which their predictions diverge.
This paper establishes a comprehensive framework for perturbative unitarity bounds in models featuring extra $SU(2)$ doublet, neutral singlet, and charged singlet scalars by proposing a minimal set of scattering matrices and providing a public Mathematica tool, BounDS, to implement and verify these constraints.
