This paper presents lecture notes from the Nordita Winter School 2024 that provide an advanced introduction to primordial inflation theory, covering both linear and non-linear perturbation theory within slow-roll and quasi-de Sitter spacetimes.
This paper introduces the Reweighting Adversarial Network (RAN), a novel unbinned unfolding technique that utilizes a particle-level reweighting function guided by a Wasserstein critic to overcome support overlap limitations and outperform state-of-the-art methods in accuracy and computational efficiency.
This paper argues that searches for fifth forces must account for the collective effects of multiple axion-like particles predicted by string theory, demonstrating that the resulting spin-dependent and spin-independent potentials can be used to distinguish between different axiverse scenarios.
This paper investigates the LHC phenomenology of a two-vector dark sector model, demonstrating that a binned analysis of the signature significantly improves sensitivity to parameter space regions consistent with the observed dark matter relic abundance compared to inclusive missing-transverse-momentum searches.
This paper develops an open quantum system framework to model neutrino flavor evolution in strong gravitational fields, deriving a Lindblad master equation that links spin-connection-induced decoherence and Kerr frame-dragging effects to observable signatures in high-energy astrophysical neutrino data from future detectors like IceCube-Gen2.
This paper introduces micrOMEGAs 7, a major software upgrade that extends dark matter calculations beyond standard cosmology by enabling user-defined modifications to the Hubble expansion and entropy evolution, while also incorporating updated experimental constraints and improved treatments for sub-GeV dark matter and indirect detection.
This paper details a path-integral computation demonstrating that worldsheet axion excitations in QCD strings significantly modify the string breaking process by inducing a varying effective tension that exponentially enhances or suppresses the nucleation of quark-antiquark pairs.
Using the Chiral quark model and the real-scaling method, this study finds no bound states for fully charmed () or fully bottomed () tetraquarks but predicts specific resonance states that could correspond to the observed and in the charmed sector and a new resonance in the bottomed sector, respectively.
This paper investigates the mechanical properties of pseudoscalar charmonium and bottomonium within the light-front quark model by evaluating gravitational form factors and analyzing their spatial distributions, revealing that while most properties are sensitive to wave function choices near the meson's center, the pressure distribution exhibits a sign-changing node and the force distribution remains positive to support stability.
This paper proposes that combining neutrino detector observations with measurements of the effective number of neutrino species and cosmic microwave background spectral distortions can uniquely identify and constrain dark matter annihilation into neutrinos with MeV-GeV masses, addressing the ambiguity of current neutrino excess signals.
