“…This treatment has the advantage of being directly gauge-independent, numerically fast to evaluate, and still yields results comparable to a more thorough gaugeindependent treatment, as seen in Ref. [60]. Note that, in this context, the scalar field VEVs are manifestly gauge invariant, and we will identify these VEVs with the corresponding scalē v introduced above.…”

“…For recent discussions of sphaleron rate computations in perturbation theory and the associated theoretical uncertainties see, e.g., Refs. [56,[58][59][60]. The dynamics of the expanding bubbles, together with the CPV transport dynamics, constitute the crucial elements for generating the left-handed number density that catalyses B + L generation.…”

We investigate the viability of electroweak baryogenesis in a model with a first order electroweak phase transition induced by the addition of two gauge singlet scalars. A vector-like lepton doublet is introduced in order to provide CP violating interactions with the singlets and Standard Model leptons, and the asymmetry generation dynamics are examined using the vacuum expectation value insertion approximation. We find that such a model is readily capable of generating sufficient baryon asymmetry while satisfying electron electric dipole moment and collider phenomenology constraints.

“…Both processes can be described by the same formalism as classical motion in Euclidean space [74]. In particular, such a solution is described by the action, 20) which can be assumed to be O(3)-symmetric in the high temperature limit [72]. Here,φ represents a solution of the Euclidean equation of motion found by computing the path that minimizes the energy [74,75].…”

The rich vacuum structure of multi-Higgs extensions of the Standard Model (SM) may have interesting cosmological implications for the electroweak phase transition (EWPT). As an important example of such class of models, we consider a particularly simple low-energy SM-like limit of a recently proposed Grand-Unified Trinification model with the scalar sector composed of two Higgs doublets and a complex singlet and with a global U(1) family symmetry. The fermion sector of this model is extended with a family of vector-like quarks which enhances CP violation. With the current study, we aim at exploring the generic vacuum structure and uncovering the features of the EWPT in this model relevant for cosmology. We show the existence of different phase transition patterns providing strong departure from thermal equilibrium. Most of these observations are not specific to the considered model and may generically be expected in other multi-Higgs extensions of the SM.

“…The gravitational wave must have an adjoint wave of matching field [35]. Because the energy of "dark matter" is the kinetic energy for expanding (or contracting) motion of universe, it is in the wrong direction to find the particle of the "dark matter" [36][37][38][39][40][41][42][43].…”

In order to unite gravitational field with other fields, we must find the common material foundation of the gravitation theory and quantum theory. For the end, I propose the duality framework of the universe. The universe is composed of continuous universal continuum and separate p net; Universal energy Eu and various special energies Es that transform into one another at high frequency; Basic forces that dominate the universe are the universal compressive force and quantum dispersive force. The above duality framework, can explain naturally the wave-particle duality, probabilistic nature, uncertainty relation and quantum entanglement; no using Einstein's theory, can obtain the mass-energy relation, Einstein's equations, Friedmann's equation and the proportions of dark energy, dark matter and ordinary matter; includes, links and foreruns both the gravitation theory and quantum theory; is their common material foundation to give their unified harmonious image; and can solve the puzzlers about the singularity, non-locality, uncertainty of energy, et al. Daring predictions: The electromagnetic wave must have an adjoint strain wave. The gravitational wave must have an adjoint wave of matching field. It is in the wrong direction to find the particle of the "dark matter".
