Query: Dynamical scales for multi-TeV top-pair production at the LHC   We calculate all major differential distributions with stable top-quarks at
the LHC. The calculation covers the multi-TeV range that will be explored
during LHC Run II and beyond. Our results are in the form of high-quality
binned distributions. We offer predictions based on three different parton
distribution function (pdf) sets. In the near future we will make our results
available also in the more flexible fastNLO format that allows fast
re-computation with any other pdf set. In order to be able to extend our
calculation into the multi-TeV range we have had to derive a set of dynamic
scales. Such scales are selected based on the principle of fastest perturbative
convergence applied to the differential and inclusive cross-section. Many
observations from our study are likely to be applicable and useful to other
precision processes at the LHC. With scale uncertainty now under good control,
pdfs arise as the leading source of uncertainty for TeV top production. Based
on our findings, true precision in the boosted regime will likely only be
possible after new and improved pdf sets appear. We expect that LHC top-quark
data will play an important role in this process.
