## How to get started with DIS

Papers and other Documents to get started with DIS

• A very nice early summary about HERA, with all the important kinematic variables Hera Physics.
• A very useful paper with a lot of equations on how to calculate things in DIS [1]
• The CTEQ tutorials
• A short intro on how hard QCD processes are calculated is here: (slides 1,2, 4, ... 10)

• a nice article on the running of apha_s
  Experimental tests of asymptotic freedom.
Siegfried Bethke (Munich, Max Planck Inst.)
Published in Prog.Part.Nucl.Phys.58:351-386,2007.
e-Print: hep-ex/0606035 http://arXiv.org/pdf/hep-ex/0606035

• Just in case you need a parametrisation for alphas here is a very nice article
  Parametrization of the QCD coupling in the Evolution Equations.
B.I. Ermolaev (Cracow, INP & Ioffe Phys. Tech. Inst.) , S.I. Troyan (St. Petersburg, INP) . May 2008. 9pp.
Published in Phys.Lett.B666:256-261,2008.
e-Print: arXiv:0805.2278 [hep-ph] http://arXiv.org/pdf/0805.2278

• There are two very nice unpolarized evolution packages available on the web:
• QCD-PEGASUS by Andreas Vogt (can be downloaded from his Liverpool homepage) The paper is hep-ph/0408244.
• HOPPET by Gavin Salam, which you can find here http://projects.hepforge.org/hoppet
