Supersymmetry is one of the most motivated scenarios for physics beyond the Standard Model. This article summarizes recent ATLAS results on searches for supersymmetry in proton-proton collisions at a centre-of-mass energy of 13 TeV at LHC, which target supersymmetric particles produced by strong interaction in events with leptonic final states. No significant excess above the Standard Model expectation is observed and exclusion limits have been set on squark and gluino masses in various scenarios.

Supersymmetry (SUSY) is one of the most relevant scenarios of new physics searched by the ATLAS experiment at the CERN Large Hadron Collider. In this writeup the principal search strategies employed by ATLAS are outlined and the most recent results f
or analyses targeting SUSY discovery are discussed. A wide range of signatures is covered motivated by various theoretical scenarios and topologies: strong production, third-generation fermions, long-lived particles and R-parity violation, among others. The results are based on up to ~5 fb-1 of data recorded during 2010-2011 at sqrt(s) = 7 TeV centre-of-mass energy by the ATLAS experiment at the LHC.
Recent results of searches for supersymmetry by the ATLAS collaboration in up to 2 fb-1 of sqrt(s) = 7 TeV pp collisions at the LHC are reported.
During the LHC Run-II data-taking period, several searches for supersymmetric particles were performed by the ATLAS collaboration. The results from these searches are concisely reviewed. Model-independent and model-dependent limits on new particle pr
oduction are set, and interpretations in supersymmetric models are given.
Differential cross sections of the reactions $pp to dpi^+$ and $pp to pnpi^+$ have been measured at $T_p = 400$ MeV by detecting the charged ejectiles in the angular range $4^0 leq Theta_{Lab} leq 21^circ$. The deduced total cross sections agree well
with those published previously for neighbouring energies. The invariant mass spectra are observed to be strongly affected by $Delta$ production and $NN$ final-state interaction. The data are well described by Monte Carlo simulations including both these effects. The ratio of $pp to pnpi^+$ and $pp to dpi^+$ cross sections also compares favourably to a recent theoretical prediction which suggests a dominance of $np$-production in the relative $^3S_1$-state.
In this paper we present a precise measurement of the total ZZ production cross section in pp collisions at {surd}s= 1.96 TeV, using data collected with the CDF II detector corresponding to an integrated luminosity of approximately 6 fb-1. The result
is obtained by combining separate measurements in the four-charged (llll), and two-charged-lepton and two-neutral-lepton (llvv) decay modes of the Z. The combined measured cross section for pp {to} ZZ is 1.64^(+0.44)_(-0.38) pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV pp collisions to date.
