FONLL

M. Cacciari, S. Frixione, P. Nason

Program to calculate heavy quark transverse momentum and rapidity distributions in hadron-hadron and photon-hadron collisions, matching Fixed Order next-to-leading order terms and Next-to-Leading-Log large-pT resummation.

FONLL v1.3.3 is available since April 9, 2014. It addresses a mismatch with a bug fix concerning the photon PDF AFG included in LHAPDF since v.5.8.5.

FONLL is compatible with gfortran since v1.3.2.

Phenomenological predictions of the FONLL formalism, including also convolution with non-perturbative fragmentation into D and B mesons (not provided by this package) can be obtained from this web page.

ChangeLog

Differences in 1.3 with respect to 1.2

Differences in 1.2 with respect to 1.1
Some changes in numerical results, especially at large rapidity, as a result of a new treatment of the large-x region of the heavy quark perturbative fragmentation function. See Cacciari, Nason, Oleari, hep-ph/0510032 and the ChangeLog for details. With this version the non-perturbative parameters given in hep-ph/0510032 should be used.

Nuclear PDF's from the EKS package, which include shadowing effects, are also available in this version. Their implementation should be considered at the beta-test stage.

Links

To install, download the FONLL-1.3.3.tgz archive, unpack it and follow the instructions in INSTALL.

Version 1.2: you must download separately the PDF data files. Download pdfdata.tgz and unpack it inside the main FONLL directory. As of version 1.3 you can use LHAPDF: you won't then need this file.
