The NA60 experiment at the CERN SPS has studied low-mass muon pairs in 158A GeV In-In collisions. The mass and pT spectra associated with peripheral collisions can quantitatively be described by the known neutral meson decays. The high data quality has allowed to remeas...

The CMS pixel detector constitutes the inner core of the tracking system. It is designed to provide three high-precision hits at least per track up to an acceptance in eta of ± 2.5. Together with the ATLAS and ALICE pixel detectors, it represents one of the biggest pixe...

Diffraction radiation (DR) is produced when a relativistic charged particle moves in the vicinity of a medium. The electric field of the charged particle polarises the target atoms which then oscillate, emitting radiation with a very broad spectrum. The spatial-spectral...

A full-scale model of the double-quarter-wave (DQW) cavity towards the High-Luminosity Large Hadron Collider (HL-LHC) upgrade was built in aluminum to characterize the deflecting mode. Field strength measurements have been carried out for both the transverse and longitu...

The machine induced background particle flux is measured by the BCM1F detector. The measured flux for fill 5111 is shown as a relative number to the measurement at the start of collisions.

The proton-proton collision events recorded by the ATLAS experiment are on top of a background that is due to both collision debris and non-collision components. The latter comprises of three types: beam-induced backgrounds, cosmic particles and detector noise. We prese...
