With anticipation of abundant Upsilons data sample at high-luminosity heavy-flavor experiments in the future, we studied nonleptonic two-body weak decays of ${\Upsilon}(nS)$ below the open-bottom threshold with $n$ $=$ $1$, $2$ and $3$. It is found that branching ratios for ${\Upsilon}(1S,2S,3S)$ ${\to}$ $B_{c}{\rho}$ decays are relatively large among upsilons decay into $B_{c}M$ final states ($M$ $=$ ${\pi}$ ${\rho}$, $K$ and $K^{\ast}$) and can reach up to $10^{-10}$, which is promisingly detected by experiments at the running LHC and forthcoming SuperKEKB.

The authors use the covariant light-front quark model to predict branching ratios of order 10^-9 to 10^-15 for weak Υ(1S-4S) → B/B_c decays, with Υ(3S) → B_c ℓν the largest.
