Book Description
The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the LHC using the CMS experiment. The data sample corresponds to an integrated luminosity of 34 inverse picobarns. The measurement is made for jet transverse momenta in the range 18-1100 GeV and for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pT ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.

Book Description
We have measured the ratio of the three-jet to two-jet inclusive cross section as a function of the total transverse energy of jets (H[sub T]=[summation]E[sup j][sub T]) in events in p[anti p] collisions at [radical]s=1.8 TeV. We find that for [summation]E[sub T]>200 GeV there is a 70% probability of emitting an additional jet with E[sub T>20 GeV. Using this measurement and the framework of the theory of Quantum Chromodynamics (QCD), we investigated the size of the renormalization scale used to model emission of ''soft'' (low-E[sub T]) jets in multijet final states. The findings indicate that, to order [alpha][sub s][sup 3] in QCD the data favor a scale representative of the hard scattering rather than a softer scale of the order of the third jet's transverse momentum. The preferred scale is [mu][sub R][approx]1/4 H[sub T].

Book Description
This paper presents a measurement of the inclusive 3-jet production differential cross section at a proton-proton centre-of-mass energy of 7 TeV using data corresponding to an integrated luminosity of 5 fb$^{-1}$ collected with the CMS detector. The analysis is based on the three jets with the highest transverse momenta. The cross section is measured as a function of the invariant mass of the three jets in a range of 445-3270 GeV and in two bins of the maximum rapidity of the jets up to a value of 2. A comparison between the measurement and the prediction from perturbative QCD at next-to-leading order is performed. Within uncertainties, data and theory are in agreement. The sensitivity of the observable to parameters of the theory such as the parton distribution functions of the proton and the strong coupling constant $\alpha_S$ is studied. A fit to all data points with 3-jet masses larger than 664 GeV gives a value of the strong coupling constant of $\alpha_S(M_\mathrm{Z})$ = 0.1171 $\pm$ 0.0013 (exp) $^{+0.0073}_{-0.0047}$ (theo).
