*Project Title: Sensitivity to beyond Standard Model physics through Higgs production at CLIC using effective field theories. Supervisor: Aidan Robson.*

*In Progress.*
---++ MADGRAPH Generating Steps

All using MADGRAPH 2.4.3, which requires Python 2.6 or 2.7. Using the Higgs Effective Lagrangian (HEL) Universal FeynRules Output (UFO) model which can be found here: https://feynrules.irmp.ucl.ac.be/wiki/HEL.

1) Start MADGRAPH:

=cd MG5_aMC_v2_4_3/bin/=

=./mg5_aMC=

This opens the MADGRAPH5_ aMC @ NLO interface.

2) Import the HEL_UFO model (which needs to have been copied to your models directory):

=import model HEL_UFO=

3) Generate electron + positron -&gt; Higgs + electron + positron events, with a new physics parameter and QED type stated.

=generate e- e+ &gt; h e- e+ QED=4 NP=1=

4) Write to output directory of name ee_hee2

=output ee_hee2=

=quit=

5) Travel to the new directory /bin/ee_hee2 and change the run card parameters as needed in file Cards/run_card.dat.

6) Start the MadEvent interface and generate events with the run card parameters specified in run_card.dat.

=cd /ee_hee2/bin/=

=./madevent=

=generate_events=

This will open a web page showing the generation progress and main parameters (such as the particle interaction and beam energies), and create an output file unweighted_events.lhe.gz in Events/run_01. A file run_01_tag_1_banner.txt is also created in /Events/run_01 listing all commands used in the MADGRAPH and MadEvent interfaces and all run card parameters used.

---++ ETA Graphs for different EFT parameters

Coming soon.
