Single-top production at linear ${e}^{−}{e}^{+}$ colliders

2018-02-20T10:00:00+00:00

Author(s): Angel Escamilla, Antonio O. Bouzas, and F. Larios

We study single-top production at linear lepton colliders with $\sqrt{s}=0.5$, 1, and 3 TeV. A preliminary analysis shows that despite the large $t\overline{t}$ background at $\sqrt{s}=0.5$ and 1 TeV it is possible to obtain a good sensitivity to the $tbW$ vertex, even more so at 3 TeV when single t...

Ghost-gluon vertex in the presence of the Gribov horizon

Author(s): B. W. Mintz, L. F. Palhares, S. P. Sorella, and A. D. Pereira

We consider Yang-Mills theories quantized in the Landau gauge in the presence of the Gribov horizon via the refined Gribov-Zwanziger (RGZ) framework. As the restriction of the gauge path integral to the Gribov region is taken into account, the resulting gauge field propagators display a nontrivial i...

Author(s): H. T. Nieh

The potential conflict between torsion and gauge symmetry in the Riemann-Cartan curved spacetime was noted by Kibble in his 1961 pioneering paper and has since been discussed by many authors.

We investigate the possible size of $h→bs$ in two-Higgs-doublet models with generic Yukawa couplings. Even though the corresponding rates are in general expected to be small due to the indirect constraints from ${B}_{s}→{μ}^{+}{μ}^{−}$ and ${B}_{s}–{\overline{B}}_{s}$ mixing, we find regions in para...

BPS sectors of the Skyrme model and their non-BPS extensions

2018-02-09T10:00:00+00:00

Author(s): C. Adam, D. Foster, S. Krusch, and A. Wereszczynski

Two recently found coupled Bogomol’nyi-Prasad-Sommerfield (BPS) submodels of the Skyrme model are further analyzed. First, we provide a geometrical formulation of the submodels in terms of the eigenvalues of the strain tensor. Second, we study their thermodynamical properties and show that the mean-...

Effects of sterile neutrinos and an extra dimension on big bang nucleosynthesis

2018-02-09T10:00:00+00:00

Author(s): Dukjae Jang, Motohiko Kusakabe, and Myung-Ki Cheoun

By assuming the existence of extra-dimensional sterile neutrinos in the big bang nucleosynthesis (BBN) epoch, we investigate the sterile neutrino (${ν}_{\mathrm{s}}$) effects on the BBN and constrain some parameters associated with the ${ν}_{\mathrm{s}}$ properties. First, for the cosmic expansion r...
