Global Fits

QuestionHow do we find dark matter and new particles?

AnswerBuild colliders, dark matter detectors, satellites and otherexperiments to hunt for them, then compare results

QuestionHow do we tell which theories are good and which are bad?

AnswerCombine the results from different searches

Global Fits

QuestionHow do we rigorously tell which theories are better than others?

Answer1. Keep the full likelihood functions, include correlations,

systematics, theoretical errors + consistent theory treatmentsacross all experiments.

(composite likelihood)

2. Test complete parameter spaces, not just single points!

(parameter estimation)

3. Test many different theories the same way!

(model comparison)

→ global fits

Global fits for dark matter and new physics

Current global fit codes are hardcoded to deal with only a fewtheories (MSSM and/or mSUGRA+friends)theory calculators (often interfaced in a very ad hoc way)datasets and observables (often missing detailed likelihoods)scanning algorithms and statistical methods (generally justone)

=⇒ hitting the wall on theories, data & computational methods

How to quickly recast data, likelihood functions, scanning code‘housekeeping’ and even theory predictions to new theories?=⇒ a new, very general global fitting framework

Modules (arXiv:1705.07908)

Physics modulesDarkBit – dark matter observables (relic density, direct +indirect detection) (arXiv:1705.07920)ColliderBit – collider observables inc. Higgs + SUSY searchesfrom ATLAS, CMS + LEP (arXiv:1705.07919)FlavBit – flavour physics inc. b → sγ, B/D decays (newchannels, angular obs., theory uncerts, LHCb likelihoods)

(arXiv:1705.07933)SpecBit – generic BSM spectrum object, providing RGErunning, masses, mixings, etc via interchangeable interfaces todifferent spectrum generators (arXiv:1705.07936)DecayBit – decay widths for all relevant SM & BSM particles

(arXiv:1705.07936)PrecisionBit – SM likelihoods, precision BSM tests (W mass,g − 2, ∆ρ etc) (arXiv:1705.07936)

Each consists of a number of module functions that can havedependencies on each other+ScannerBit: manages stats, sampling and optimisation(arXiv:1705.07959)

Hierarchical Model Database (arXiv:1705.07908)

Models are defined by their parameters and relations to eachotherModels can inherit from (be subspaces of) parent modelsPoints in child models can be automatically translated toancestor modelsFriend models also allowed (cross-family translation)Model dependence of every function/observable is tracked=⇒ maximum safety, maximum reuse

Backends: mix and match (arXiv:1705.07908)

Module functions can require specific functions frombackendsBackends are external code libraries (DarkSUSY, FeynHiggs,Pythia, SUSYHD, etc) that include different functionsGAMBIT automates and abstracts the interfaces to backends→ backend functions are tagged according to what theycalculate→ with appropriate module design, different backends andtheir functions can be used interchangeablyGAMBIT dynamically adapts to use whichever backends areactually present on a user’s system (+ provides details ofwhat it decided to do of course)backends can be C/C++, Fortran, Mathematica or Python

Module functions and backend functions get arranged into adependency treeStarting with requested observables and likelihoods, GAMBITfills each dependency and backend requirementObeys rules at each step: allowed models, allowed backends,constraints from input file, etc→ tree constitutes a directed acyclic graph→ GAMBIT uses graph-theoretic methods to ‘solve’ the graphto determine function evaluation order

Expansion: adding new observables and likelihoodsAdding a new module function is easy:1. Declare the function to GAMBIT in a module’s rollcall header

Choose a capabilityDeclare any backend requirementsDeclare any dependenciesDeclare any specific allowed modelsother more advanced declarations also available

#define MODULE FlavBit // A tasty GAMBIT module.START_MODULE

#define CAPABILITY Rmu // Observable: BR(K->mu nu)/BR(pi->mu nu)START_CAPABILITY

#define FUNCTION SI_Rmu // Name of a function that can compute RmuSTART_FUNCTION(double) // Function computes a double precision resultBACKEND_REQ(Kmunu_pimunu, (my_tag), double, (const parameters*)) // Needs function from a backendBACKEND_OPTION( (SuperIso, 3.6), (my_tag) ) // Backend must be SuperIso 3.6DEPENDENCY(SuperIso_modelinfo, parameters) // Needs another function to calculate SuperIso infoALLOW_MODELS(MSSM63atQ, MSSM63atMGUT) // Works with weak/GUT-scale MSSM and descendents#undef FUNCTION

#undef CAPABILITY

2. Write the function as a standard C++ function(one argument: the result)


G A M B I T

Expansion: adding new models

1. Add the model to the model hierarchy:Choose a model name, and declare any parent modelDeclare the model’s parametersDeclare any translation function to the parent model

#define MODEL NUHM1#define PARENT NUHM2

START_MODELDEFINEPARS(M0,M12,mH,A0,TanBeta,SignMu)INTERPRET_AS_PARENT_FUNCTION(NUHM1_to_NUHM2)

#undef PARENT#undef MODEL

2. Write the translation function as a standard C++ function:void MODEL_NAMESPACE::NUHM1_to_NUHM2 (const ModelParameters &myP, ModelParameters &targetP)

// Set M0, M12, A0, TanBeta and SignMu in the NUHM2 to the same values as in the NUHM1targetP.setValues(myP,false);// Set the values of mHu and mHd in the NUHM2 to the value of mH in the NUHM1targetP.setValue("mHu", myP["mH"]);targetP.setValue("mHd", myP["mH"]);

3. If needed, declare that existing module functions work withthe new model, or add new functions that do.


G A M B I T

Interface: yaml file

Basic interface for a scan is a YAML initialisation file

- specify parameters, ranges, priors- select likelihood components- select other observables tocalculate

- define generic rules for how to filldependencies

- define generic rules for options tobe passed to module functions

- set global options (scanner,errors/warnings, logging behaviour,etc)

LEP likelihoodscomplete model-independent recast of direct sparticle searches

Higgs likelihoods:for now: HiggSignals + HiggsBounds + constraints frominvisible fits (Bernon, Dumont, Kraml et al)future: full simulation and ATLAS+CMS combination, morecorrelations, CP info, no SM-like coupling assumptions

Fast LHC likelihoodsno simplified models, just faster direct simulation


G A M B I T

ColliderBit details

LHC likelihoods:MC generation: Pythia8 parallelised with OpenMP + other speed tweaks

Detector simulation: fast simulation based on 4-vector smearing→ matches DELPHES results very closely (but much faster!)Cross-sections: LO + LL from MC generator by default (fast NLO inworks for SUSY)Analysis framework: custom event-level, independent of experiment orsimulationLikelihood: inline systematic error marginalisation (via nulike)

Initially shipping with:

ATLAS SUSY searches (0`, 0/1/2` t, b jets + MET, 2/3`EW)CMS multi-` SUSYCMS DM (t pair + MET, mono-b, monojet)ATLAS + CMS Run II 0`refresh coming with more Run II analyses shortly
