This paper demonstrates that primordial temperature fluctuations modulate the axion mass during the QCD phase transition to trigger parametric resonance, which significantly enhances axion production and shifts the viable dark matter mass window to the higher range of .
This paper resolves the hyperfine puzzle in hydrogen, which suggests a variational collapse due to a energy term, by demonstrating that accounting for the proton's finite size yields a stable ground state with a radius indistinguishable from the Bohr radius.
This paper presents a systematic, gauge-invariant framework using worldline effective field theory and scattering amplitudes to compute gravitational Raman scattering at third post-Minkowskian order, demonstrating that while leading static Love numbers for black holes vanish, dynamical Love numbers exhibit logarithmic running that resolves previous off-shell ambiguities across various dimensions and spin fields.
This paper constructs a high-temperature effective field theory for gauge-Higgs models up to by integrating out hard modes to the three-loop level, deriving new mass and coupling parameters, and demonstrating that one-loop dimension-six effects typically dominate over higher-loop corrections in determining gravitational-wave observables for strong phase transitions.
By analyzing NANOGrav 15-year data to model the impact of initial galactic center density and binary eccentricity on the gravitational wave spectrum, this study infers a preferred parsec-scale central density of approximately , suggesting that stellar and dark matter ejections significantly shape the evolution of supermassive black hole binaries.
This paper presents a systematic decomposition of QCD splitting functions up to second order in the strong coupling into universal scalar dipole radiators and pure splitting remainders, utilizing multipole radiator functions that capture essential soft and collinear features without relying on kinematical approximations.
This paper extends the pion-nucleus multiple-scattering framework to include second-order rescattering dynamics and nuclear structure details derived from chiral effective field theory, demonstrating that these corrections are essential for accurately reproducing differential cross sections in -Ca elastic scattering within the -resonance region.
This study establishes stringent constraints on lepton flavor violating dark matter scenarios by analyzing astrophysical photon and positron data from XMM-Newton, INTEGRAL, Fermi-LAT, and AMS-02, revealing that INTEGRAL and AMS-02 provide the most competitive bounds for dark matter masses below and above approximately 20 GeV, respectively.
This paper investigates two-body non-leptonic weak decays, demonstrating that long-distance triangle rescattering processes mediated by pion exchange dominate over negligible short-distance contributions, and provides theoretical predictions for branching fractions of specific channels to guide future experimental studies at BESIII, Belle(-II), and LHCb.
This study incorporates long-lived "prompt cusps" into a hierarchical substructure framework to demonstrate that these compact remnants can significantly enhance the dark matter annihilation boost factor in Milky-Way-sized halos to approximately 50, while revealing that unifying peak-based formation with merger-tree evolution yields lower abundance estimates than universal-average models.
