Description
We present a framework for resumming logarithms of the jet veto $\ln p_T^\text{cut}/Q$
in color-singlet production at forward rapidities,
where approaching the "lopsided threshold" $Y \to Y_\text{max}$ imposes additional constraints on the modes present in the usual $p_T^\text{jet}$ factorization.
We discuss the relevant regimes and factorization theorems
and show how to consistently extend estimates of the resummation uncertainty by $Y$-dependent profile scales.
We give numerical results for gluon fusion at $Q = m_H$ as well as for a generic heavy scalar resonance
and for Drell-Yan production at selected values of $Q$.
