Fundamentals of LHC Experiments

June 1 2011 Abstract Experiments on the Large Hadron Collider at CERN represent our furthest excursion yet along the energy frontier of particle physics The goal of probing physical processes at the TeV energy scale puts strict requirements on the performance of accelerator and experiment dictating the awe-inspiring dimensions of both

Why is the sensitivity of LHC experiments limited?
The sensitivity to resonances is limited by background contamination and invariant mass resolution, both of which are high priorities for the LHC experiments. If some of the decay products from the new resonance are invisible (non- interacting), a simple invariant mass calculation will not capture the signal. In these cases, the transverse mass
What is the expected rate of collisions in the LHC?
During early LHC operations a typical value of ? has been 1:5 m. To calculate the expected rate of collisions in the LHC, we de ne the instan- taneous luminosity L, measured in units of area 1time 1. Ultimately phase of the LHC will reach instantaneous luminosities of 1034 cm 2s 1 at full in- tensity.
How do LHC experiments work?
The LHC experiments use a combination of low-level hardware and high-level software triggers to lter events for further study. In the hardware triggers, indi- vidual trigger objects (jets, electromagnetic clusters, muons) are identi ed using data from fast readout detectors. These are passed to streamlined versions of
What is missing transverse energy in LHC experiments?
The LHC experiments de ne the missing transverse energy as the opposite of the vector transverse sum of all detected particles. Such a measurement is only relevant if the detectors are nearly hermetic to both charged and neutral particles; this has put strict requirements on the hermeticity of the experiments.
