2 Outline Introduction Renormalization scheme Physical results Summary
3 Introduction Why RC is important? Precise O(1%) measurement at LC Same accuracy of Theoretical predictions RC in MSSM renormalization, mass spectrum, decays, production (Higgs, chargino / neutralino, sfermion) Fritzsche, Hollik / Eerl, Majerotto, Yamada et al. / Denner / Öller, Eerl, Majerotto / Hollik, Rzehak / Arhri, Hollik / Kovarik, Weer, Eerl, Majerotto / Freitas, Miller, von Manteuffel, Zerwas / Guasch, Hollik, Solà etc.
4 Why automatic calculation is needed? SUSY Models Many possile processes for SUSY particle production a large numer of Feynman diagrams FeynArts & FormCalc Küleck, Böhm, Denner / Hahn, Perez-Victoria / Hahn / Hahn, Schappacher CompHEP & LanHEP Moscow group / Boudjema, Bèlanger, Semenov... see Boudjema s talk
