Abstract: A bstractWe calculate the complete-NLO predictions for tt¯W±$$ t\overline{t}{W}^{\pm } $$ and tt¯tt¯$$ t\overline{t}t\overline{t} $$ production in proton-proton collisions at 13 and 100 TeV. All the non-vanishing contributions of Oαsiαj$$ \mathcal{O}\left({\alpha}_s^i{\alpha}^j\right) $$ with i +… read more here.

DOI: 10.1007/jhep05(2018)024
Abstract: A bstractWe explore supersymmetric contributions to the decay KS0 → μ+μ−, in light of current experimental data. The Standard Model (SM) predicts ℬKS0→μ+μ−≈5×10−12$$ \mathrm{\mathcal{B}}\left({K}_S^0\to {\mu}^{+}{\mu}^{-}\right)\approx 5\times {10}^{-12} $$. We find that contributions arising from flavour violating Higgs… read more here.
