Jets and threshold summation in deductor

Abstract: We explore jet physics in hadron collisions using the parton shower event generator DEDUCTOR. Of particular interest is the one jet inclusive cross section dσ=dP T for jets of very high P T . Compared to the Born level, the cross section decreases substantially because of P T loss from the jet during showering. We compare to the same effect in PYTHIA and DIRE. The cross section then increases substantially because of the summation of threshold logarithms included in DEDUCTOR. We also study the cross section to… Show more

“…This choice is motivated in Ref. [10]. Results do not change much if we choose a larger value for µ s because the Deductor splitting kernel restricts the splitting transverse momentum to be no greater than P Born T in order to ensure that the scattering that initiates the shower is the highest P T scattering in the event.…”

“…First, just after the hard scattering, Deductor inserts an operator U V that produces a summation of threshold logarithms [10]. The operator U V gives results as an expansion in powers of ∆V Re .…”

“…They treat QCD color in the leading color (LC) approximation, that is at leading order in an expansion in powers of 1/N 2 c , where N c = 3 is the number of colors. Previous versions of our parton shower generator, Deductor [4][5][6][7][8][9][10][11][12][13], use what we call the LC+ approximation [7], which includes some terms suppressed by powers of 1/N 2 c . This paper concerns improvements in the color treatment in Deductor that could be applicable to other parton shower generators.…”
