[*] Wide scalar resonance X->VV in CMS:
- What is the interesting parameter range to present in terms of mass, width, etc. for theorists?
can be model-dependent, may think in a specific model that has large mass and width without breaking perturbativity,
useful with up to ~20-40% on width, though 40% is very challenging in experiment
though keeping model less dependent would always be good
- In wide ggF/VBF need also the interference;
do it in model independent way by using the ME reweighting tool; float both VBF/ggF;
- Does higgs 125 coupling change in different cases?
No
- Slide 3: take the ME to generate event and to reweight for interference, not ideal, but pragmatic
if you have one of the curves, you can reweight it to other curves (like in WW on slide5).
[*] EWS in ScannerS:
- Can be used for various multi Higgs models (also 2HDM etc); EWS is interfaced to sHDecay.
Constraints: vacuum stability, tree level unitarity, STU, collider, h125, DM.
Manual explanation on how to run it (also has manual and papers)!
Before the BR/Width are calculated the unitarity validity is taken into account.
[*] Heavy Higgs to mu tau LFV:
- Will provide numbers for BR/XS for X->mutau (mX!=125) in the (BGL) model and numbers for BR/XS for H+->taunu in the Lepton Specific model.
[*] Light charged higgs:
- Study the motivation for pair production.
maybe 2HDM type III can be a starting point
There are minutes attached to this event.
