This paper presents a forecast study demonstrating that a stacking analysis of very-high-energy gamma-ray observations from active galactic nuclei located behind galaxy clusters can probe Axion-Like Particle dark matter in the to eV mass range, achieving sensitivity to ALP-photon couplings as low as GeV.
This paper proposes that the Dark Technicolour paradigm, utilizing the Extended Most Attractive Channel hypothesis across three confining gauge sectors, revitalizes conventional Technicolour dynamics to generate Standard Model fermion masses and resolve the Flavor Problem through a hierarchical structure of multifermion condensates.
This paper introduces a novel class of critical unstable qubits characterized by orthogonal energy and decay-width vectors, revealing their unique coherence-decoherence oscillations and defining anharmonicity observables to quantify these effects within neutral-meson systems.
This paper investigates neutrino flavor evolution in high-flux astrophysical environments like supernovae and neutron star mergers, demonstrating that non-forward scattering and many-body dynamics lead to rapid energy and flavor equilibration, which significantly impacts nucleosynthesis and terrestrial neutrino observations.
This paper presents a coherent S-matrix treatment of the entire neutrino experimental chain that reveals non-factorizable corrections arising from spin and angular correlations, which introduce significant systematic shifts in energy spectra and enable the direct measurement of Majorana CP phases, thereby challenging the standard factorization assumption crucial for next-generation precision neutrino physics.
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 utilizes $SU(3)$ flavour symmetry and recent CP asymmetry measurements from LHCb and Belle-II to constrain penguin decay contributions, thereby enabling high-precision extractions of the Standard Model phases and and outlining future prospects for the HL-LHC and Belle-II experiments.
This paper investigates the sensitivity of a 2 TeV same-sign muon collider (μTRISTAN) to eight distinct dimension-seven SMEFT operators via processes, demonstrating its potential to probe lepton number violation beyond existing LHC constraints and future FCC projections.
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 investigates how dark dipole radiation from eccentric supermassive black hole binaries can accelerate their inspiral and alter the low-frequency stochastic gravitational-wave background, finding that while it cannot fully resolve the final-parsec problem, it remains detectable through Bayesian analysis of current pulsar timing array data.
