Monte Carlo study of $\Upsilon(1S)$ production in jets in the forward region

The Large Hadron Collider beauty (LHCb) experiment primarily studies the production and decay of beauty and charm hadrons. Different from ATLAS and CMS, which mainly cover the mid-rapidity region, the LHCb detector uniquely covers the forward region $(2<\eta<5)$ with precise tracking and particle identification capabilities. A recent study of $J/\psi$ production in jets presents the first measurement of transverse momentum fraction, $z(J/\psi) = p_{T}(J/\psi)/p_{T}(jet)$, in the forward region. Despite the consistency between theoretical predictions and measurements of $z(J/\psi)$ from b-hadron decays, a disagreement is found for prompt $J/\psi$ production. It inspires parallel studies of the production of prompt upsilons in jets, to compare charmonium in jets to heavier bottomonium particles. Here, an analysis of ground state upsilons $(\Upsilon(1S))$ in jets in the forward region with Monte Carlo events generated at a center-of-mass energy of 8 TeV will be presented. The energy and transverse momentum $(p_{T})$ distributions for inclusive $\Upsilon(1S)$ will be shown, and the calculations including $z(\Upsilon)$, longitudinal momentum fraction $(z)$, radial distance $(r)$ and momentum transverse $(j_{T})$ to jet axis will be performed for $\Upsilon(1S)$ in jets.
