High Energy Diffraction at the LHC via Combinatorial (incidence) Algebra
Framework with novel constructions and algorithms:
- Unfolded multidimensional 'fiducial vector cross sections'
- Multivariate Maximum Likelihood fit extraction of the effective Pomeron intercept 1 + Δ
- Multivariate Maximum Likelihood fit extraction of the diffractive cross sections (SD, DD, ND) and the maximum diffractive mass dependence (minimum average rapidity gap size <ΔY>)
- Möbius inversion of pileup
- Multidimensional algebraic hierarchy of detector level distributions (raw multiplicity etc.) - highly constraining comparison with MC models, probing AGK rules / multipomeron cuts / soft multiparton interactions

External dependencies:
- ALICE experiment software (FYI: algorithms here are fully experiment generic)
- RooUnfold (in /libs, no license)
- csv parser (in /libs, BSD-3 license)
- cxxopts CLI parser (in /libs, MIT license)
In general, one needs to modify Makefile a bit for your local installation. See Makefile for instructions.
Install
1. AliPhysics/AliROOT installation (ROOT5 based setup is tested to work)
Tested on Ubuntu 18
