Precision BSM ============= - improved Born approximations: effective couplings, mixing angles etc. - 'classifying' relevant HO corrections: 'generic' rules of thumb? generic origins of sizeable corrections? Shape uncertainties? Universality of HO corrections (e.g. DY, DIS-like)? Speed up existing codes, when moving to HO? - realistic estimates of uncertainties for BSM predictions: sources, sizes, PDF uncertainties (how large is the uncertainty of missing BSM corrections in the PDF fits themselves? <- SMEFT fits by NNPDF) - changes of shapes of distributions: 'generic' list where relevant? Sources (large logs, double logs, gluonic initial states etc.)? - RGEs for SMEFT and other EFTs, decoupling of contributions to the running for LHC physics? Proper implementation of input scale and physical scales, shifts of input parameters, translations of different bases at HOs, impact of canonical normalization? E.g. d_t alpha_s = beta(NF,alpha_s) + c MH^2/Lambda^2 c_HG = light quark loops + top loop + Higgs loop <- decouple top, Higgs ==> d_t alpha_s = beta(5,alpha_s) - backgrounds (<-> Session 1): tails of distributions, uncertainties (shapes, normalization), list of relevant background processes - relevance of interference effects: SM+BSM, BSM+BSM -> rules of thumb? typical size? - missing calculations: wishlist? - what to do with BSM models that are not renormalizable? Uncertainties estimable? (guess not...) Agreed tasks ============ Andi Crivellin: QED corrections to light charged scalar production Engage experimentalists
