Measurement of forward $t\overline{t}, W + b\overline{b}$ and $W + c\overline{c}$ production in $pp$ collisions at $\sqrt{s}$ = 8 TeV


LHCb Collaboration; Bernet, R; Müller, K; Serra, N; Steinkamp, O; Straumann, U; Vollhardt, A; et al (2017). Measurement of forward $t\overline{t}, W + b\overline{b}$ and $W + c\overline{c}$ production in $pp$ collisions at $\sqrt{s}$ = 8 TeV. Physics Letters B, B767:110-120.

Abstract

The production of $t\overline{t}, W + b\overline{b}$ and $W + c\overline{c}$ is studied in the forward region of proton–proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated luminosity of $1.98 \pm 0.02 fb^{−1}$. The Wbosons are reconstructed in the decays $W \to \ellν$, where $\ell$ denotes muon or electron, while the $b$ and $c$ quarks are reconstructed as jets. All measured cross-sections are in agreement with next-to-leading-order Standard Model predictions.
