The non-singlet kaon fragmentation function from e^+e^- kaon production

S. Albino, E. Christova

We perform fits to the available charged and neutral kaon production data in $e^{+} + e^{-} \to K + X$ , $K = K^{\pm} an d K_{S}^{0}$ , and determine the non-singlet combination of kaon fragmentation…

CP violation in charged Higgs decays in the MSSM

E. Christova, H. Eberl, E. Ginina +1

In the MSSM with complex parameters loop corrections to the decays $H^{+} \to t b ˉ$ and $H^{-} \to t ˉ b$ with $t \to bW$ and $W \to l ν$ lead to CP-violating asymmetries: a…

CP violation in e+e- -> t tbar: Energy Asymmetries and Optimal Observables of b and bbar Quarks

A. Bartl, E. Christova, T. Gajdosik +1

The energy spectra of the b and bbar quarks in e+e- -> t tbar with t -> b W (tbar -> bbar W) are calculated assuming CP violation in the production process. Expressions for the cor…

CP-violating asymmetries in top-quark production and decay in $e^{+} e^{-}$ annihilation within the MSSM

A. Bartl, E. Christova, W. Majerotto

We obtain analytic formulae for the cross section of the sequential processes of $e^{+} e^{-} \to t t ˉ$ and $t \to b l ν$ in the laboratory frame where the dependence on triple pro…

T Violation Induced by Supersymmetry in t\bar{t} and W^+W^- Physics

E. Christova, M. Fabbrichesi

T-odd correlations of polarizations and momenta provide a promising testing ground for new physics beyond the standard model. We estimate the contribution of the minimal supersymme…
