Vector/Axial-vector Technical stuff: - use POWHEG-BOX process of pp-->DM DM 1j at NLO (need to check how sufficient this will be for - vector coupling to both SM and DM multijet+Met processes) - axial vector coupling to both SM and DM - use generation cut of 30 GeV, 50000 events each - no mixed coupling case yet (we can add later) model. (previously used 20k events with a cut of 80 GeV, this was sufficient for monojets, but likely not sufficient for multijet analyses) Width is calculated from couplings from using following formulas g q g DM M med M DM
Vector/Axial-vector g q g DM Proposal for scans: M med M DM Vary M med and M DM and keep g q and g DM fixed to 0.3, 0.5, 1.0, 1.45 - (weak coupling, semi-weak coupling, strong coupling, max coupling based on width~mass) - Ranges depend on values of couplings g q =g DM =0.3 M DM = 25, 50, 75, 100, 125, 150, 175, 200 M MED = 50, 100, 200, 300, 400, 500, 600, 700, 800 g q =g DM =0.5 M DM = 25, 50, 100, 150, 200, 250, 300 M MED = 50, 100, 200, 400, 600, 800, 1000, 1100, 1200 g q =g DM =1.0 M DM = 25, 50, 100, 150, 200, 250, 300, 350 ,400, 450, 500 M MED = 50, 100, 200, 400, 600, 800, 1000, 1100, 1200, 1300, 1400, 1500 g q =g DM =1.45 M DM = 25, 50, 100, 150, 200, 250, 300, 350 ,400, 450, 500, 550, 600, 650 M MED = 50, 100, 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400, 2600
Scalar/Pseudoscalar - use MCFM - yukawa coupling to quarks ONLY, not to DM. - 50k events each with generation cut of 30 GeV g q =g DM =0.1 M DM = 25, 50, 75, 100, 125, 150, 175, 200 M MED = 50, 125, 200, 300, 400, 500, 600, 700, 800 g q =g DM =1.0 M DM = 25, 50, 100, 150, 200, 250, 300, 350 M MED = 50, 100, 200, 400, 600, 800, 1000, 1100, 1200 Higgs invisible scan, g q = 1.0, g DM = x (value of coupling which gives width of Higgs) M MED = 125, M DM = 50 g q =g DM =2.0 M DM = 25, 50, 100, 150, 200, 250, 300, 350, 400 M MED = 50, 100, 200, 400, 600, 800, 1000, 1100, 1200,1400 g q =g DM =3.2 (max coupling for which mass ~ width) M DM = 25, 50, 100, 150, 200, 250, 300, 350 ,400, 450, 500, 550 M MED = 50, 125, 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000
