NLO-NNLL higgsino-like N2C1 cross sections

The following cross sections are for higgsino-like chargino-neutralino pair production (sum of χ̃+1χ̃02 and χ̃-1χ̃02, and also for each subprocess individually). They have been calculated for sqrt(s) = 27 TeV at NLO-NNLL using Resummino 2.0.1 from B. Fuks et al. The Monte Carlo PDF set with 100 replicas PDF4LHC15_mc is used, which is a statistical combination of CT14, MMHT14 and NNPDF3.0, all using αs(mZ2) = 0.118. The use of this combination of PDF sets is recommended for searches for new Physics by the PDF4LHC Working Group. See https://arxiv.org/abs/1510.03865 for more details.

The cross sections are computed for degenerate charginos and neutralinos. The mass is denoted as mχ̃. The following sentence describes all the assumptions in the cross section calculations and is suitable to be included in the description of the interpretation of your results:

The production cross sections are computed at NLO plus
next-to-next-to-leading-log (NNLL) precision in a limit of mass-degenerate
higgsino $\chiz_2$, $\chipm_1$, and $\chiz_1$ with all the other sparticles
assumed to be heavy and decoupled.

When using these cross sections, some references have to be cited. They can be found below in bibtex format. The references can also be downloaded from this Twiki, see attachments at the bottom.

To calculate these cross sections, this repository can be used. The SLHA files can be found there as well: wino.in and hino.in.

Should cross section information be needed for a mass that is not tabulated below, one can obtain it by using the ROOT macros provided under:

/afs/cern.ch/user/a/amete/public/EWKGauginoCrossSections_13TeV

For this specific grid one needs to do:

root -l 'get_gaugino.C("C1N2", "hino", mass)' 

where mass is the mass of the sparticle in GeV. The result of the interpolation can be seen here.
