This paper calculates enhanced electroweak, QCD, and QED radiative corrections to the nucleon coupling constants and , providing updated relations between lattice-QCD and physical values that yield a total correction of approximately 3.5% to 5.6% and predict a physical axial charge of 1.265(26) or 1.240(9) depending on the input methodology.
This paper proposes a -based inverse seesaw model that successfully explains neutrino mass hierarchies and cobimaximal mixing patterns while accounting for the observed baryon asymmetry of the Universe via leptogenesis in the normal mass hierarchy scenario.
The paper demonstrates that the final state of a binary black hole merger corresponds with remarkable accuracy to the configuration that maximizes the instability rate of null geodesics, suggesting a deep connection between merger dynamics and the efficiency of photon ring scrambling.
This paper establishes new constraints on the mixing angle of light CP-even scalars with the Standard Model Higgs boson by analyzing non-detections of gamma-ray excess from SN1987A in historical Solar Maximum Mission satellite data, which would have resulted from scalars produced via nucleon bremsstrahlung and subsequently decaying into photons.
This paper proposes that quantum sensors can detect bursts of ultralight bosonic fields emitted during violent astrophysical events, thereby establishing a new multimessenger astronomy channel that remains viable even when accounting for matter screening effects.
This semi-historical article provides a basic presentation of quantum field theory's mathematical formalism and its essential features, such as particle creation and destruction, to readers familiar with classical and non-relativistic quantum mechanics while also aiming to engage interested non-physicists.
This paper proposes a novel mechanism for generating high-frequency gravitational waves at approximately Hz through gravitational transition radiation, where particles emit gravitons as their masses change while traversing expanding bubble walls during first-order phase transitions in the early Universe.
This study utilizes PYTHIA 8 and EPOS-LHC models to demonstrate that particle-identified balance functions in 13 TeV proton-proton collisions exhibit distinct dependencies on event multiplicity and spherocity, revealing that while PYTHIA 8 reflects fragmentation-dominated dynamics, EPOS-LHC captures collective effects like radial flow and diffusion that mimic heavy-ion behavior, thereby offering a powerful tool to disentangle hadronization mechanisms and medium-like collectivity in small collision systems.
This paper demonstrates that the Witten-O'Raifeartaigh potential can support a unified cosmological model where Warm Inflation occurs on its steep left wing and transient dark energy arises on its flatter right wing, provided the potential is normalized differently for each era and the quintessence field incorporates dissipative dynamics to sustain slow-roll.
This paper explores extending Bimetric MOND (BIMOND) to create variable- theories that naturally satisfy local constraints on the constancy of Newton's constant while allowing for a different, enhanced effective gravitational constant () in cosmological settings to potentially explain dark matter effects without new degrees of freedom.
