Inclusive KT Jet Cross Section (S. Grinstein's
thesis, M. Strang, D. Elvira, R. Piegaia)
The KT jet
algorithm offers several advantages with respect to the fixed cone algorithm.
First, the absence
of cone boundaries avoids out-of-cone showering losses. Second, it
can be implemented in the same way at all levels (parton level theoretical
calculation, final state particle level Monte Carlo, calorimeter
cells), therefore eliminating the split/merge ambiguity. In addition, the
algorithm is infrared safe at all orders in a perturbative QCD calculation.
The inclusive jet cross section using the KT jet algorithm becomes
an interesting measurement given the existance of a precise
result by D0 (cone), the availability of higher than NLO predictions,
plus the possibility of achieving smaller experimental uncertainties .
