This is the page for the DISResum package, which calculates resummed distributions for event shapes in the Breit frame in Deep Inelastic Scattering. It embodies work presented in JHEP 02 (2000) 001, Phys. Lett. B512 (2001) 323, Eur. Phys. J. C24 (2002) 213 and other articles currently in preparation with Mrinal Dasgupta.

The current version is disresum-1.1.6. Relative to version 1.1.5 the default value of X (esRescaleV) has been changed for the broadening and thrust measured with respect to the photon axis and normalised to the current-hemisphere energy. A bug has also been fixed in the parameterisation of non-global logarithms --- this has about a 1% effect on fits for the strong coupling. Note also that the 1.1.x series also contains significant changes relative to the 1.1.0 series. Please see the CHANGELOG file in the distribution, as well as the documentation.

NB:This is work currently under development. Accordingly not everything is final. In particular fixed-order calculations, which are required for the package to work, are supported only in the form generated by DISPATCH.
