There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce sources of CP violation, and there be mixing between multiple bosons or other scalar bosons. Alternatively, a composite state, even no at all. scenarios have important implications collider as well cosmology, understanding their phenomenology is essential full comprehension electroweak symmetry breaking. This report discusses most relevant theories which go its...
We consider the effective two-Higgs-doublet potential with complex parameters, when $CP$ invariance is broken both explicitly and spontaneously. The diagonal mass term in local minimum of constructed for physical basis Higgs fields, keeping limiting case conservation, if parameters are taken real. For special two-doublet sector minimal supersymmetric model, violated by bosons interaction scalar quarks third generation, we calculate means method boson masses evaluate two-fermion decay widths...

The miniature and low-power devices with long service life in hard operating conditions like the Carbon-14 beta-decay energy converters indeed as eternal resource for integrated MEMS NEMS are considered.

In the minimal supersymmetric standard model (MSSM) one-loop finite-temperature corrections from squark-Higgs bosons sector are calculated, effective two-Higgs-doublet potential is reconstructed and possibilities of electroweak phase transition in full MSSM ( , ) parameter space studied. At large values around 1 TeV, favored indirectly by LEP2 Teva-tron data, threshold triangle box diagrams with intermediate third generation squarks very substantial. Four types bifurcation sets defined for...

We investigate the Higgs bosons decay width in framework of NMSSMin one-loop approximation. The sector under consideration contains CP-violation general case due to explicit and spontaneous violations CP-symmetry. local minimum conditions for physical states are taken into account as necessary requirements. So, calculation reduces corresponding processes amplitudes. strategy is based on perturbation theory.
To construct beta converters with maximum efficiency it is necessary to carry out the theoretical calculation in order determine their optimal parameters - geometry of structure, thickness deposition radioisotope layer, depth and width p-n junction, others. date, many different models calculations methods had been proposed. There are fairly simple based on Bethe-Bloch formula rate generation electron-hole pairs, by equivalent circuits. Also, Monte-Carlo method used for modeling converters....
