+ | CP-even scalar: | ||
+ | mphi in [10, 100] GeV | ||
+ | f0B in [1, 10] TeV | ||
+ | f0W in [1, 10] TeV | ||
+ | f0H in [1, 10] TeV | ||
+ | |||
+ | CP-odd scalar: | ||
+ | mphi in [10, 100] GeV | ||
+ | f0B in [1, 10] TeV | ||
+ | f0W in [1, 10] TeV | ||
+ | |||
+ | For each case, all the other f's should be set to very large values. | ||
+ | |||
+ | So, here is a scan using these ranges for the CP-odd scalar model (f0 value labelled $\Lambda$ on the vertical axis, $M_\phi$ on the horizontal. | ||

+ | ... so this is looking pretty promising. Everything excluded except the lowest mass/highest scale. This needs to be carefully checked, of course. All the yellow region above is excluded by the ATLAS diphoton cross sections: [[http://inspirehep.net/record/1591327|arXiv:1704.03839]]. If those are not included, the [[http://inspirehep.net/record/1448301|ATLAS $Z+\gamma$ measurements]] (in dilepton+photon and MET+photon) have quite some power on their own, see below. | ||

+ | Remember, big caveat on this is that the data is assumed to exactly agree with the SM, which means (given we only really know that these data are //consistent// with the SM) that we are neglected the SM theory uncertainties. | ||

Not really sure of what sensible parameter ranges would be at the moment, but here is an example run for CP-Odd scalar with some 8 TeV data. I (Jon) set $m_\phi = 80$ GeV, and setting the mass scales for the effective couplings at 50 or 100 TeV as follows: $f0B, f0W, f0H, f0gam, f0Z = 50$ TeV, $f0G, f0u, f0d, f0l = 100$ TeV. Total cross section is $4.4 pb^{-1}$. | Not really sure of what sensible parameter ranges would be at the moment, but here is an example run for CP-Odd scalar with some 8 TeV data.

Next step? Agree some sensible parameter ranges to scan, presumably mass and some subset of couplings; I can combine 7, 8 and 13 TeV limits, of course. | Next step?
