Top Quark Properties
Abstract
Recently, experimental collaborations have reported O(10) upper limits on the signal strength of four-top production at the LHC, which already leads to competitive constraints on certain type of top-quark operators. On the other hand, developments in the b-jet charge tagging algorithms open up new possibilities for the direct measurement of the top-quark width. In this talk, we briefly discuss some recent studies in these two directions.
