  We present the first threshold and jet radius jointly resummed cross section
for single-inclusive hadronic jet production. We work at next-to-leading
logarithmic accuracy and our framework allows for a systematic extension beyond
the currently achieved precision. Longstanding numerical issues are overcome by
performing the resummation directly in momentum space within Soft Collinear
Effective Theory. We present the first numerical results for the LHC and
observe an improved description of the available data. Our results are of
immediate relevance for LHC precision phenomenology including the extraction of
parton distribution functions and the QCD strong coupling constant.
