Search for walking technipion in four-jet sample
  We discuss how to search for a possibe signal of the recently observed 750 GeV enhancement in the diphoton channel in the four-jet production. In the present studies we assume that the produced state is pseudoscalar. This fact, when combined with specificity of the corresponding amplitude, allows to improve the signal-to-background (S/B) ratio. We discuss in detail how to impose cuts on jets in rapidity and transverse momenta in order to find optimal S/B ratio and not to loose too much statistics. Our study suggest a measurement of two soft (low cut on $p_t$) large-rapidity jets and two hard (high cut on $p_t$) mid-rapidity jets. Azimuthal correlation between the soft external jets may be useful to further improve the situation. Several differential distributions in rapidities and transverse momenta of jets as well as dijet invariant mass are shown. The integrated cross sections corresponding to different cuts are collected in a table and number of events are presented.
