A Precise Determination of $I^\pm_{s}$ from the Heavy Jet Mass Distribution

Miguel A. Benitez, Arindam Bhattacharya, Andre H. Hoang +4

A global fit for $I^\pm_{s} (m_{Z})$ is performed on available $e^{+} e^{-}$ data for the heavy jet mass distribution. The state-of-the-art theory prediction includes $O (I^\pm_{s}^{3})$ fixe…

Endpoint Factorization for Semileptonic Decays of Boosted and Resonant Off-Shell Top Quarks with a Large-Radius Bottom Jet

Andre H. Hoang, Christoph Regner

We derive a factorization formula for boosted double resonant top-antitop pair production in $e^{+} e^{-}$ annihilation with a semileptonic top quark decay in the phase space region whe…

Precision $e^{+} e^{-}$ Hemisphere Masses in the Dijet Region with Power Corrections

Andre H. Hoang, Vicent Mateu, Matthew D. Schwartz +1

We derive high-precision results for the $e^{+} e^{-}$ heavy jet mass (HJM) $d I ¨ / d I ¨ $ and dihemisphere mass (DHM) $d^{2} I ¨ / (d s_{1} d s_{2})$ distributions, for $s_{1} \sim s_{2}$ , in the dijet…

Matching Hadronization and Perturbative Evolution: The Cluster Model in Light of Infrared Shower Cutoff Dependence

AndrÃ© H. Hoang, Oliver L. Jin, Simon PlÃ¤tzer +1

In the context of Monte Carlo (MC) generators with parton showers that have next-to-leading-logarithmic (NLL) precision, the cutoff $Q_{0}$ terminating the shower evolution should be…

Three-Loop OPE Wilson Coefficients of Dimension-Four Operators for (Axial-)Vector and (Pseudo-)Scalar Current Correlators

We calculate the three-loop Wilson coefficients of all physically relevant dimension-four operators, i.e. $G_{I^¼ I^½}^{a} G^{a, I^¼ I^½}$ , $m_{i} q ˉ_{j} q_{j}$ and $m_{i} m_{j} m_{k}^{2}$ , in the sho…

On Determining $I^\pm_{s} (m_{Z})$ from Dijets in $e^{+} e^{-}$ Thrust

Miguel A. Benitez, Andre H. Hoang, Vicent Mateu +2

We update a previous N $^{3}$ LL $^{'}$ + $O (I^\pm_{s}^{3})$ determination of the strong coupling from a global fit to thrust data by including newly available perturbative ingredients…
