Parameterizing the SFC Baryogenesis Model
Published 2015-01-01“…We have investigated the evolution of the baryon charge carrying field, the evolution of the baryon charge contained in the scalar field condensate, and the final value of the generated baryon charge on the model’s parameters: the gauge coupling constant α, the Hubble constant at the inflationary stage HI, the mass m, and the self-coupling constants λi.…”

Backreacted Coulomb energy in the Skyrme model
Published 2025-01-01“…The Coulomb energies are slightly larger than phenomenological fits suggest, but only by about 3 – 22%, whereas the radii are within 15% errors, with the largest errors on the smallest baryon number (B = 4) and the smallest errors on the large baryon numbers.…”

5σ tension between Planck cosmic microwave background and eBOSS Lyman-alpha forest and constraints on physics beyond ΛCDM
Published 2025-01-01“…We find that combined Planck cosmic microwave background, baryon acoustic oscillations, and supernovae data analyzed under Λ cold dark matter (ΛCDM) are in 4.9σ tension with the extended Baryon Oscillation Spectroscopic Survey (eBOSS) Lyα forest in inference of the linear matter power spectrum at wave number ∼1hMpc^{−1} and redshift = 3. …”

Modular A4 invariance and leptogenesis
Published 2020-01-01“…It is shown that masses of right-handed neutrinos are about 1013 GeV in order to account for the observed baryon asymmetry of the universe. Furthermore, the positive sign of the baryon asymmetry is obtained only for the limited ranges of mixing angles and CP violation phases of active neutrinos, which can be tested by future neutrino experiments.…”

Cosmic Microwave Background as a Thermal Gas of SU(2) Photons: Implications for the High-z Cosmological Model and the Value of H0
Published 2017-01-01“…Observationally, we rely on precise low-frequency intensity measurements in the CMB spectrum and on a recent model independent (low-z) extraction of the relation between the comoving sound horizon rs at the end of the baryon drag epoch and H0 (rsH0=const). We point out that the commonly employed condition for baryon-velocity freeze-out is imprecise, judged by a careful inspection of the formal solution to the associated Euler equation. …”
