This dissertation investigates two key phenomenological consequences of axions: deriving constraints on their mass and symmetry breaking scale by computing the density power spectrum of axions emitted from cosmic strings, and analyzing the gravitational wave signals generated by superradiant axion clouds around spinning black holes perturbed by binary companions.
This paper investigates the arithmetic structure of modulus vacua in flux compactifications, revealing that supersymmetric minima exhibit patterns like the Farey sequence, display void structures correlated with degeneracy, and are interconnected by discrete Abelian symmetries derived from the Gauss composition law that include CP symmetry.
This paper presents an updated exclusive determination of the CKM matrix element as by combining Belle II data with advanced lattice-QCD and SCET sum-rule calculations, while highlighting a persistent tension between the resulting Standard Model predictions for and and current experimental averages.
Using the Modified Richardson–Lucy algorithm to reconstruct the primordial power spectrum across all CMB-accessible scales with Planck, ACT, and SPT-3G data, the study finds no significant deviations from a power-law spectrum and confirms strong consistency between datasets, while showing that the previously suggested blueward tilt in ACT data is only preferred at the level.
This paper combines the latest experimental muon and electron measurements to establish 95% CL exclusion contours for light vector bosons, revealing that while direct searches leave certain parameter regions near the mass open, the cesium-based electron constraint specifically excludes the higher-coupling interval for both dark photons and independent-coupling scenarios.
This paper proposes a third-generation-philic Hidden Naturalness solution to the electroweak hierarchy problem, utilizing a specific composite Higgs model to significantly raise the new physics scale and reduce fine-tuning while evading current direct search constraints.
This paper demonstrates that hybrid quantum-classical algorithms, including QAOA, FALQON, and VarQITE, significantly outperform conventional kinematic methods and match or exceed machine learning techniques in solving the combinatorial pairing problem for top quark pair production at the Large Hadron Collider, offering a scalable and training-free alternative for high-energy physics applications.
This paper proposes an dark grand unification model where a shared asymmetry generation mechanism and similar gauge coupling running naturally explain the comparable energy densities of dark matter and baryons by predicting GeV-scale dark baryons and a TeV-scale mediator.
This paper demonstrates that spatially varying matter potentials can suppress or significantly delay fast neutrino flavor conversions in supernovae, revealing a critical variation rate beyond which instabilities are stabilized and highlighting the necessity of accounting for matter inhomogeneity in supernova models.
This paper presents the first study of charge-dependent two-particle number and transverse momentum balance functions in pp collisions at TeV, revealing that balance functions narrow with increasing multiplicity and are wider in isotropic than jet-like events, while comparing PYTHIA8 and EPOS-LHC models to isolate hydrodynamic radial-flow effects on charge conservation.
