### Abstract

The production of χb1P mesons in $pp$ collisions at a centre-of-mass energy of $7\tev$ is studied using $32∈vpb$ of data collected with the \lhcb detector. The $χb1P$ mesons are reconstructed in the decay mode $χb1P \to \Y1S\g \to μmu\g$. The fraction of \Y1S originating from χb1P decays in the \Y1S transverse momentum range $6 < \pt^\Y1S < 15≥vc$ and rapidity range $2.0 < y^\Y1S < 4.5$ is measured to be $(20.7± 5.7± 2.1^+2.7_-5.4)%$, where the first uncertainty is statistical, the second is systematic and the last gives the range of the result due to the unknown \Y1S and χb1P polarizations.
