Comparison of approximate to exact next-to-next-to leading order corrections for Higgs and pseudoscalar Higgs boson production
A. P. Contogouris, P. K. Papachristou
Recently obtained NNLO exact corrections for Higgs and Pseudoscalar Higgs boson production in hadron colliders are compared with approximate ones. As shown before, it is found that…
A Model for the Color Glass Condensate Versus Jet Quenching
A. Contogouris, F. K. Diakonos, P. K. Papachristou
A model for the Color Glass Condensate as opposed to jet quenching is proposed for the explanation of the presently available RHIC data. Good fits to these data are presented. A cl…
Approximate Next-to-Leading Order and Next-to-Next-to-Leading Order Corrections
A. P. Contogouris, Z. Merebashvili
For processes involving structure functions and/or fragmentation functions, arguments that, over a range of a proper kinematic variable, there is a part that dominates the next-to-…
Approximate calculation of corrections at NLO and NNLO
A. P. Contogouris, G. Grispos
For processes involving structure functions and/or fragmentation functions, arguments that there is a part that dominates the NLO corrections are briefly reviewed. The arguments ar…
