---+ NLO-NNLL higgsino-like !N2C1 cross sections The following cross sections are for higgsino-like chargino-neutralino pair production (sum of χ̃<sup>+</sup><sub>1</sub>χ̃<sup>0</sup><sub>2</sub> and χ̃<sup>-</sup><sub>1</sub>χ̃<sup>0</sup><sub>2</sub>, 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 α<sub>s</sub>(m<sub>Z</sub><sup>2</sup>) = 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 m<sub>χ̃</sub>. 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: <verbatim> 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. </verbatim> When using these cross sections, some references have to be cited. They can be found below in bibtex format.
