Search for supersymmetric mesinos near production threshold in terms of superflavor symmetry

Supersymmetry （SUSY） may be one of the most favored extensions of the Standard Model （SM）, but so far at the LHC no evidence of SUSY particles has been observed. An obvious question is whether they have already emerged but escaped our detection, or whether they do not exist at all. We propose that t...

Description
Summary:Supersymmetry （SUSY） may be one of the most favored extensions of the Standard Model （SM）, but so far at the LHC no evidence of SUSY particles has been observed. An obvious question is whether they have already emerged but escaped our detection, or whether they do not exist at all. We propose that the future ILC may provide sufficient energy and luminosity to produce SUSY particles as long as they are not too heavy. Superflavor symmetry associates production rates of SUSY mesinos with those of regular mesons, because both contain a heavy constituent and a light one. In this work, we estimate the production rate of SUSY mesinos near their production threshold and compare it with BB production. Our analysis indicates that if SUSY mesinos with masses below √s/2 （√s is the ILC energy） exist, they could be observed at the future ILC or even the proposed CEPC in China.
