A study of the sensitivity to the Pythia8 parton shower parameters of $t\bar{t}$ production measurements in $pp$ collisions at $\sqrt{s} = 7$ TeV with the ATLAS experiment at the LHC
Various measurements of $t\bar{t}$ observables, performed by the ATLAS experiment in $pp$ collisions at $\sqrt{s} = 7$ TeV, are used to constrain the initial- and final-state radiation parameters of the Pythia8 Monte Carlo. [...]

A search for $B-L$ $R$-Parity violating scalar top decays in $\sqrt{s} = 8$ TeV $pp$ collisions with the ATLAS experiment
A search is presented for direct scalar top pair production where the scalar tops decay via an $R$-parity-violating coupling to a final state with two leptons and two identified $b$-jets. [...]

Study of the $B_c^+ \to J/\psi D_s^+$ and $B_c^+ \to J/\psi D_s^{*+}$ decays with the ATLAS detector
The decays $B_c^+ \to J/\psi D_s^+$ and $B_c^+ \to J/\psi D_s^{*+}$ are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 fb$^{-1}$ and 20.6 fb$^{-1}$ of $pp$ collisions collected at centre-of-mass energies $\sqrt{s} = 7$ and $8$ TeV, respectively.

Search for metastable heavy charged particles with large ionisation energy loss in pp collisions at sqrt (s) = 8 TeV using the ATLAS experiment
Many extensions of the Standard Model predict the existence of charged and heavy long-lived particles, such as R-hadrons or charginos. [...]
