Postsphaleron Baryogenesis [PDF]
Physical Review Letters, 2006 We present a new mechanism for generating the baryon asymmetry of the universe directly in the decay of a singlet scalar field $S_r$ with a weak scale mass and a high dimensional baryon number violating coupling. Unlike most currently popular models, this mechanism, which becomes effective after the electroweak phase transition, does not rely on the ...

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we have investigated the density perturbations and cosmological evolution in the FLRW universe in the presence of a cosmic magnetic field, which may be assumed to mimic primordial magnetic fields. Such magnetic fields have sufficient strength to influence galaxy formation and cluster dynamics, thereby leaving an imprint on the CMB ...

Constraint on the Higgs‐Dilaton Potential via Warm Inflation in Two‐Time Physics
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Within the SP(2, R) symmetry, the two‐time model (2T model) has six dimensions with two dimensions of time and the dilaton field that can be identified as inflaton in a warm inflation scenario with potential of the form ~ϕ4. From that consideration, we derive the range of parameters for the Higgs‐Dilaton potential, the coupling constant between Higgs ...

On Lorentz Invariant Complex Scalar Fields
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We obtain a Lorentz covariant wave equation whose complex wave function transforms under a Lorentz boost according to the following rule, Ψ(x)⟶e(i/ℏ)f(x)Ψ(x). We show that the spacetime‐dependent phase f(x) is the most natural relativistic extension of the phase associated with the transformation rule for the nonrelativistic Schrödinger wave function ...

Relaxing the W′ Constraint on Compact Extradimension
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we study the constraint on brane tension and compactification scale for models with brane fluctuations using the results from the direct search of W′ at 13 TeV LHC, with an integrated luminosity of 36.1fb−1, in the case for which branon forms the entire cold dark matter.

T‐Odd Anomalous Interactions of the Top‐Quark at the Large Hadron Collider
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We study the effects of T‐odd interactions of top‐quark via the pair production of the top‐quark in the semileptonic detection modes at the Large Hadron Collider by means of the T‐odd observables constructed through the momenta of the observed decay products of the top (and anti‐top)‐quark for a wide range of CP‐violating scale Λ.
