We show that Majorana neutrino flavor mixing can be driven by transition dipole moments in the presence of external electromagnetic fields. We demonstrate the sensitivity of the rotation mixing matrix to strong fields obtaining dynamical mass eigenstates in the two-flavor model. The three-flavor case and extensions to the quark sector are introduced.

In this paper, we report on generalized half-dyon solutions in SU(2) Yang–Mills–Higgs theory, namely Type I and Type II solutions. These solutions are constructed by considering [Formula: see text]-winding number [Formula: see text], electric charge parameter [Formula: see text] and Higgs self-coupling constant [Formula: see text]. They represent system of magnetic charge [Formula: see text] ([Formula: see text]) and electric charge [Formula: see text] that lies along the negative (positive) [Formula: see text]-axis. Fundamental properties, such as total energy, electric charge, dipole moment, are explored and discussed.

We introduce the notion of cumulative activity for inelastic events generated under hadron collisions, discuss its energy dependence and connection with the reflective scattering mode. These issues are relevant for enlightening the asymptotic dynamics in view of the LHC measurements.

Recently, Ai, Bender and Sarkar gave a prescription on how to obtain $mathcal{PT}$-symmetric field theory results from an analytic continuation of Hermitian field theories. I perform this analytic continuation for the massless (critical) O(N) model with quartic interaction in 3+1 dimensions. In the large N limit, this theory is exactly solvable, and has negative $beta$-function in the ultraviolet, and a stable bound state in the infrared. The coupling diverges at a scale $Lambda_c$, but can be continued into the far infrared. At finite temperature, the theory exhibits two phases separated by a second-order phase transition near $T_csimeq Lambda_c/sqrt{e}$.

This paper proposes a basic method for understanding stationary particle production on manifolds by means of the Stokes phenomenon. We studied the Stokes phenomena of the Schwinger effect, the Unruh effect and Hawking radiation in detail focusing on the origin of their continuous particle production. We found a possibility that conventional calculations may not explain the experimental results.

We present a review of Witten index calculations in different supersymmetric gauge theories in four dimensions: supersymmetric electrodynamics, pure N=1 supersymmetric Yang-Mills theories and also SYM theories including matter multiplets -- both with chirally symmetric and asymmetric content.

The Two-time model (2T model) has six dimensions with two dimensions of time, has a dilaton particle that makes the symmetry breaking differently from the Standard Model. Assuming a soft break of $SP(2,R)$ symmetry, the 2T extension can give a suitable picture of the matter-antimatter asymmetry by the Baryogenesis scenario. By reducing the 2T metric to the Minkowski metric (1T metric), we consider the electroweak phase transition picture in the 2T model with the dilaton as the trigger. Our analysis shows that Electroweak Phase Transition (EWPT) is a first-order phase transition at the $200$ GeV scale, its strength is about $1 - 3.08$ and the mass of dilaton is in the interval $[345,625]$ GeV. Therefore, the 2T-model indirectly suggests that extra-dimension can also be a source of EWPT.
