Measurement of inclusive and exclusive dijet production ratio at large rapidity intervals at $\sqrt{s

We present a first measurement of the ratio of inclusive to exclusive dijet production as a function of the absolute distance in rapidity, $\vert \Delta y \vert$, between jets. The measurement was performed with the CMS detector in proton-proton collisions at $\sqrt{s}=7$ TeV for jets with $\ensuremath{p_{\mathrm{T}}}\xspace > 35$ GeV and $\vert y\vert<4.7$ using an integrated luminosity of $33$ nb$^{-1}$ ( $5$ pb$^{-1}$) for dijets with moderate (large) rapidity separation. The measured ratio of inclusive to exclusive dijet events is compared with predictions from various Monte Carlo event generators.
