Collider limits on new physics within micrOMEGAs4.3
Results from the LHC put severe constraints on models of new physics. This
includes constraints on the Higgs sector from the precise measurement of the
mass and couplings of the 125GeV Higgs boson, as well as limits from searches
for other new particles. We present the procedure to use these constraints in
micrOMEGAs by interfacing it to the external codes Lilith, HiggsSignals,
HiggsBounds and SModelS. A few dedicated modules are also provided. With these
new features, micrOMEGAs_4.3 provides a generic framework for evaluating dark
matter observables together with collider and non-collider constraints.Comment: 23 page
Logic Programming Approaches for Representing and Solving Constraint Satisfaction Problems: A Comparison
Many logic programming based approaches can be used to describe and solve
combinatorial search problems. On the one hand there is constraint logic
programming which computes a solution as an answer substitution to a query
containing the variables of the constraint satisfaction problem. On the other
hand there are systems based on stable model semantics, abductive systems, and
first order logic model generators which compute solutions as models of some
theory. This paper compares these different approaches from the point of view
of knowledge representation (how declarative are the programs) and from the
point of view of performance (how good are they at solving typical problems).Comment: 15 pages, 3 eps-figure
