The GAMBIT Universal Model Machine: from Lagrangians to likelihoods
نویسندگان
چکیده
We introduce the GAMBIT Universal Model Machine (GUM), a tool for automatically generating code global fitting software framework GAMBIT, based on Lagrangian-level inputs. GUM accepts models written symbolically in FeynRules and SARAH formats, can use either along with MadGraph CalcHEP to generate model, collider, dark matter, decay spectrum code, as well interfaces corresponding versions of SPheno, micrOMEGAs, Pythia Vevacious (C++). In this paper we describe features, methods, usage, pathways, assumptions current limitations GUM. also give fully worked example, consisting addition Majorana fermion simplified matter model scalar mediator via GUM, carry out fit.

Fawcett et al. correctly identified a problem: despite repeated calls for a greater integration of psychological and biological approaches, most behavioral ecologists still study the evolution of behavioral strategies rather than the evolution of the learning mechanisms that produce or shape these strategies.

متن کاملBeyond the Standard Model with Effective Lagrangians
We discuss some applications of the effective quantum field theory to the description of the physics beyond the Standard Model. We consider two different examples. In the first one we derive, at the one-loop level, an effective lagrangian for an extension of the Standard Model with a charged scalar singlet by “integrating out” the heavy scalar. In the second example we illustrate the use of gen...
