The DIRAC experiment at CERN has achieved a sizeable production of $\pi^+\pi^-$ atoms and significantly improved the precision on its lifetime determination. From sample 21227 atomic pairs, 4% measurement S-wave $\pi\pi$ scattering length difference $|a_0-a_2| = (.0.2533^{+0.0080}_{-0.0078}|_\mathrm{stat}.{}^{+0.0078}_{-0.0073}|_\mathrm{syst})M_{\pi^+}^{-1}$ been attained, providing an important test Chiral Perturbation Theory.

The CMS Endcap Preshower (ES) sub-detector comprises 4288 silicon sensors, each containing 32 strips. data are transferred from the detector to counting room via 1208 optical fibres running at 800Mbps. Each fibre carries two, three or four sensors. For readout of Preshower, a VME-based system, Data Concentrator Card (ES-DCC), is currently under development. main objective board acquire on-detector up 36 links, perform on-line reduction zero suppression and pass concentrated event builder....

During the first years of LHC operation a large amount jet data was recorded by ATLAS and CMS experiments. In this review several measurements jet-related observables are presented, such as multi-jet rates cross sections, ratios shapes event shape observables. All results presented here based on collected at centre-of-mass energy 7 TeV. Data compared to various Monte Carlo generators, well theoretical next-to-leading-order calculations allowing test perturbative Quantum Chromodynamics in...
