- | * Binoth Les Houches Accord (BLHA); There will be an update on this. [[http://phystev.in2p3.fr/wiki/_media/2013:groups:sm:blhaupdate.pdf|Pdf file]] of the write-up | + | 1) **PDFs** |
- | * | + | |
- | * | + | |
- | * ... | + | |
+ | a) impact of LHC data, current and future | ||
+ | * -how well do we know PDFs at high x->implications for new physics | ||
+ | * -how Gaussian are high x PDF uncertainties, i.e. what would it take to believe a high mass excess | ||
+ | |||
+ | b) impact of/need for an LHeC | ||
- | ===Coordination with Snowmass: QCD Issues=== | + | c) combination of PDF sets |

+ | d) impact of NNLO jet calculations | ||
+ | 2) **(N)NLO QCD + (N)NLO EWK** | ||
+ | a) wishlist of calculations-> review of what current exists->input: what do the experiments really want? | ||
+ | |||
+ | b) study of the 'Sudakov Zone', ~1 TeV where EWK corrections may be comparable to QCD corrections | ||
+ | |||
+ | c) PDFs with QED corrections, photon PDFs, gamma-gamma processes | ||
+ | |||
+ | d) press ahead with the tuned comparison of precision calculations for Drell-Yan processes carried out in the framework of the LPCC EW Group | ||
+ | |||
+ | e) prescriptions for combining QCD and EW corrections | ||

+ | === EW corrections - theoretical guidelines and eexperimental issues === | ||
+ | == Theoretical guidelines: == | ||
+ | * EW input parameter schemes \\ Which to use in which process / for which corrections, etc. | ||
+ | * Photon radiation \\ Their role in NC/CC processes, general features, collinear non-safety versus KLN inclusiveness, etc | ||
+ | - photon-induced processes \\ their size in various processes, how to fix the photon PDF, EW factorization scheme, etc. | ||
+ | - EW Sudakov logs \\ quality of a leading-log approximation for NLO EW corrections, real W/Z emission, two-loops and beyond, etc. | ||
+ | |||
+ | == Experimental issues: == | ||
