It provides the latest combined measurements and new findings on top quark properties, asymmetries, CP violation, and exotic hadrons from Tevatron experiments.

Findings

Precise top quark mass measurements and combinations.

Observation of forward-backward asymmetry in top pair production.

Evidence for a four-flavor tetraquark state.

Abstract

We discuss recent results obtained by the D0 experiment at the Fermilab Tevatron $p\bar p$ collider and recent combinations of CDF and D0 measurements. Regarding the top quark mass, we present recent measurements obtained at D0, the final Run~I+Run~II D0 combination, as well as the preliminary Run~I+Run~II CDF+D0 combination. We also discuss the combination of the CDF+D0 measurements of the $p\bar p \to t\bar t$ forward-backward asymmetry. We present the first measurement of the direct CP-violating charge asymmetry in $B^\pm$ mesons decaying to $\mu^\pm D^{0} X$, and discuss the status of the recent evidence for a four-flavor tetraquark state seen at D0.
