Higgs Self Coupling

1. "trilinear-FF" (The form factor code to run VH, VBF and Hto4l)

In this folder we provide: a) "loop_hvv" : the UFO model folder with modified VVH vertices due to trilinear couplings at one-loop

b) "hvvcoef.cpp": C++ implementation of form factors

c) "Makefile": to generate static library (libhvvcoef.a) which is used during event generation

d) "ReadMe.txt": explains how to use the code step by step and benchmarking for HZ process

2. "trilinear-RW" (The Reweighting code to run VH,VBF,tHj and ttH)
   

In this folder we provide:

a) "hhh-model": the UFO model file to be used

b) "gvirt.sh": auxiliary script to generate virtual EW subprocesses

c) "vvh-loop_diagram_generation.py" : to select right set of one-loop diagrams in VH, VBF and tHj

d) "tth-loop_diagram_generation.py": to select right set of one-loop diagrams in ttH

e) "check_OLP.f": reweighting code

f) "makefile": makefile for reweighting code

g) "ReadMe.txt": explains how to use the code step by step and benchmarking for HZ process

h) we also provide "example_hz" folder which contains a simple script to build the reweighting

code for HZ as an example

(All calculations are done in G_\mu scheme and benchmarking is done with MG5_aMC_v2_5_5)
