Fast and efficient methods for the calibration and the alignment of the detector are a key asset to exploit the physics potential of the CMS detector.
The CMS experiment has set up a powerful framework for alignment and calibration, which is based on dedicated skims providing a highly compact dedicated input for the various workflows computing the constants. This includes a prompt...

We present results on the jet energy calibration and jet transverse momentum resolution at CMS. In-situ measurements are performed using couple of 100/pb of proton-proton collisions at 7 TeV center of mass energy. The transverse momentum balancing in dijet and photon/Z+jet events is used to measure the jet energy response in the CMS detector, as well as the transverse momentum resolution. The...

A precision luminosity measurement is of critical importance for the ATLAS physics program, both for searches for new physics as well as for precision measurements of Standard Model cross-sections. The calibration of the luminosity is based on three so-called van der Meer scans that were performed in 2010.
The calibration determines the convolved beam sizes in the vertical and horizontal...

Tau leptons will play an important role in the physics program
at the LHC. They will be used not only in searches for new
phenomena like the Higgs boson or Supersymmetry and electroweak
measurements but also in detector related studies like the
determination of the missing transverse energy scale.
Identifying hadronically decaying tau leptons requires good
understanding of the...

In this talk we report comprehensive results of studies of missing transverse energy (MET) measured by the CMS detector in pp collisions at a centre-of-mass energy of 7 TeV. Three MET reconstruction algorithms are deployed for various physics analyses. The scale and resolution for MET are validated using vector boson and dijet events, and severe mismeasurements due to the detector are studied....

Progress in experimental particle physics in the coming decade depends crucially upon the ability to carry out experiments at high energies and high luminosities. These two conditions imply that future experiments will take place in very high radiation areas. In order to perform these complex and perhaps expensive experiments new radiation hard technologies will have to be developed. ...
