Measurement of the charm-mixing parameter $y_{CP}$
A measurement of the charm-mixing parameter $y_{CP}$ using $D^0 \to K^+ K^-$, $D^0 \to \pi^+ \pi^-$, and $D^0 \to K^- \pi^+$ decays is reported. [...]

Parton Shower and Matching Uncertainties in Top Quark Pair Production with Herwig 7 / Cormier, Kyle ; Plätzer, Simon ; Reuschle, Christian ; Richardson, Peter ; Webster, Stephen
We evaluate the theoretical uncertainties in next-to-leading order plus parton shower predictions for top quark pair production and decay in hadronic collisions. [...]

Tests of QCD using jets at CMS / Cerci, Salim (Cukurova U.) /CMS Collaboration
Inclusive jets, dijets and multijets measurements can be utilized to test perturbative quantum chromodynamics (QCD) predictions and to measure the strong coupling constant $\alpha_{S}$ as well as to constrain parton distribution functions (PDFs). In this talk, the recent measurements using the $pp$ collisions data collected with the CMS detector at the LHC at different center-of-mass energies are presented..

Constraining D-foam via the 21-cm Line / Ellis, John ; Mavromatos, Nick E. ; Nanopoulos, Dimitri V.
We have suggested earlier that D-particles, which are stringy space-time defects predicted in brane-inspired models of the Universe, might constitute a component of dark matter, and that they might contribute to the masses of singlet fermions that could provide another component. [...]
