On this website, you can plot transverse momentum distributions for cross sections of several particle reactions. Currently, the following processes are implemented (p corresponds both to protons and antiprotons):
 
The
output figure shows distributions
for the
production of onshell particles (or pairs of onshell particles
in the case of the and ZZ production)
with specified invariant mass , rapidity and transverse
momentum in the lab frame (the centerofmass frame of the hadron
beams). You can plot resummed, fixedorder and asymptotic cross sections. For
a short explanation of these quantities, visit this page (for
a detailed explanation see, for instance, a paper by J.C. Collins, D.E. Soper
and G. Sterman in Nucl. Phys. B250, 199 (1985)).
 
Please note that this website is not designed for long and CPUconsuming studies. Instead, the main goal of this website is to illustrate basic features of the bspace resummation formalism.
 
Note that many cross sections for the decaying finalstate particles at multiple values of and are already calculated; they can be downloaded as grid files from our Internet portal on transverse momentum resummation. The ResBos family of MonteCarlo programs are designed to read in the grid files with the cross sections, interpolate and integrate them to produce various differential distributions.
