     1=== Description of the UFO models to generate Dirac magentic monopoles
     2
     3Dirac magentic monopoles can be generated by Drell-Yan process or photon fusion process. The UFO models shown here describe both the processes and generate the corresponding LHE files. These models were tested for three spin cases (0, 1/2 and 1) and two processes (photon fusion and Drell-Yan).
     4a. velocity independent coupling models: mono_spinzero, mono_spinhalf and mono_spinone.
     5b. velocity dependent coupling models: mono_spinzero_beta, mono_spinhalf_beta, mono_spinone_beta.
     6
     7Details of these models can be found in arXiv:1808.08942.

     9A. Instructions to run Drell-Yan spin zero model:
     10
     11    a. Part 1 of the script to run spin zero monopole model (put the following snippet in a textfile named 'Spin0ScriptDY.txt'):
     12    '''
     13    import model mono_spinzero_beta
     14    generate p p > a > mm+ mm-
     15    output Pre5For
     16
     17    '''
     18
     19    b. Part 2 of the script to run spin zero monopole model (put the following snippet in a textfile named 'Spin0ScriptDY2.txt'):
     20
     21    '''
     22    launch Pre5For
     23    analysis=MADANALYSIS_4
     24    set run_card ebeam1 6500
     25    set ebeam2 6500
     26    set lpp1 1
     27    set lpp2 1
     28    set pdlabel nn23lo1
     29    set lhaid 230000
     30    set nevents 1000
     31    set dynamical_scale_choice -1
     32    set fixed_couplings False
     33    set param_card mass 25 125
     34    set mass 4110000 6000
     35    set decay 4110000 0.000000e+0
     36    set gch 1 1.0
     37
     38    '''
     39
     40
     41    c. Run the part 1 of the script: ./bin/mg5_aMC Spin0ScriptDY.txt
     42
     43    d. A new folder named Pre5For will be generated.
     44
     45    e. Go to Pre5For/Sources and open genps.inc.
     46
     47    f. Use the absolute path of 'maxparticles.inc' on line 5.
     48
     49    g. Run the part 2 of the script: ./bin/mg5_aMC Spin0ScriptDY2.txt
     50
     51    h. If you don't change the part 1 of the script at all (you only need to change it to import different monopole models), then you just need to use steps c-f only once. After that, in step g, change the mass parameter in script 2 and run for different mass points.
     52
     53    i. For different spin models, one just needs to import those corresponding models in the part 1 of the script.
