Top Quark Continues To Behave As Expected

New data from the Large Hadron Collider, reported by the CMS experiment in pre-prints here and here, continues to show that top quarks behave as expected in the Standard Model, tightly constraining a variety of beyond the Standard Model physics parameters. If this sounds familiar, it is because it should as in the following posts in the last couple of years:

* Top quark width and W boson helicity as expected.

* Top quark width constrains BSM physics.

* Top quark width in relatable units.

Pole mass v. MS mass conversion factor for top quarks converges quickly.

* Hadronic measurements of top quark mass confirm other measurements of it, ATLAS and CMS top quark mass measurements are consistent with each other, ATLAS top quark mass measurements, CMS measures top quark mass, and more top quark mass measurements, and yet more top quark mass measurements, and Tevatron top quark mass measurements.

* The evidence against the existence of a t' quark and along the same lines here.

UPDATE November 13, 2017:

* Top quark charge asymmetry is also observed to be tightly in line with Standard Model predictions.
