Baryogenesis from primordial CP violation

Journal of High Energy Physics
We present a novel baryogenesis mechanism in a three-Higgs doublet model. The lightest doublet plays the role of the standard Higgs, and there are two heavier Higgs bosons.

A natural model of spontaneous CP violation

Journal of High Energy Physics, 2022
We examine the possibility of building a natural non-supersymmetric model of spontaneous CP violation equipped with the Nelson-Barr (NB) mechanism to address the strong CP problem.

Leptonic CP violation and leptogenesis [PDF]

International Journal of Modern Physics A, 2014
The phenomenology of 3-neutrino mixing, the current status of our knowledge about the 3-neutrino mixing parameters, including the absolute neutrino mass scale, and of the Dirac and Majorana CP violation in the lepton sector, are reviewed. The problems of CP violation in neutrino oscillations and of determining the nature — Dirac or Majorana — of ...

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

Advanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

CP violation at finite temperature

Journal of High Energy Physics
We present a comprehensive study of the finite temperature CP-asymmetry factor needed in the semi-classical treatment of leptogenesis originating from Majorana fermion decays into a lepton and a scalar particle.

CP violation of the loop induced H± → W±Z decays in the general two Higgs doublet model* [PDF]

EPJ Web of Conferences
New sources of CP violation are necessary to solve the problem of the baryon asymmetry of the Universe. Extending the Higgs sector is one way to introduce such new CP violating phases, and studying observables resulting from the CP violation is important

Review on CP violation

AIP Conference Proceedings, 1994
A phenomenological description of the neutral K and B meson systems is presented. The situation of the current CP violation experiments is described and a detailed discussion of their results is given, followed by some future prospects.

Motion and Morphology Planning for Autonomous Manipulation in Clutter With a Shape‐Shifting, Variable‐Stiffness Robot

Advanced Intelligent Systems, EarlyView.
A hybrid mobile robot with a modular Variable‐Stiffness Bridge transitions between a rigid locomotion platform and a flexible, shape‐conforming body. By enclosing objects within its deformable structure rather than relying on dedicated end effectors, the robot achieves orientation‐regulated planar transport, with conformal contact quality shown to ...

Pseudo-Goldstone dark matter model with CP violation

Journal of High Energy Physics, 2022
We consider an explicitly CP-violating model with two Higgs doublets and one complex singlet scalar. The singlet S is charged under a global U(1) symmetry which is softly broken by a mass term μ 2 S 2 + H.c..
