Code to Calculate the Shuvaev Transform


The Shuvaev Transform

The Shuvaev Transform

Skewed parton distributions can be determined at small x and ξ from diagonal partons by the use of the Shuvaev transform.

For the details of the Shuvaev transform see A. Shuvaev, Phys. Rev. D 60 (1999) 116005. For details of its application see A. Shuvaev et al., Phys. Rev. D 60 (1999) 014015.

Interpolation Routine and Grid Files

We have developed a fast and efficient Fortran interpolation routine to use in conjunction with grid files to obtain skewed distributions from global partons based on the Shuvaev transform, see arXiv:0812.3558 for details. Gridfiles are provided for:

MSTW2008LO

MSTW2008NLO

MRST2004LO

MRST2004NLO

CTEQ6L

CTEQ6.6M

See the Durham HEPDATA webpage for more details and for parton distribution function sources. More grid files can be produced upon request.
