On Determining $\alpha_s(m_Z)$ from Dijets in $e^+e^-$ Thrust
/ Benitez, Miguel A. (Salamanca U., IUFFyM) ; Hoang, Andre H. (Vienna U.) ; Mateu, Vicent (Salamanca U., IUFFyM) ; Stewart, Iain W. (Vienna U. ; MIT) ; Vita, Gherardo (CERN)
We update a previous N$^3$LL$^\prime$+${\cal O}(\alpha_s^3)$ determination of the strong coupling from a global fit to thrust data by including newly available perturbative ingredients, upgrading the renormalization scales to include a fully canonical scaling region, and implementing the log resummation in a way which ensures the integrated cross section is unaffected by the the leading $1/Q$ hadronization power corrections.

Effective temperatures of the QGP from thermal photon and dilepton production
/ Massen, Olaf (Utrecht U. ; NIKHEF, Amsterdam) ; Nijs, Govert (CERN) ; Sas, Mike (Utrecht U. ; NIKHEF, Amsterdam ; CERN) ; van der Schee, Wilke (NIKHEF, Amsterdam ; CERN ; Utrecht U.) ; Snellings, Raimond (Utrecht U. ; NIKHEF, Amsterdam)
Thermal electromagnetic radiation is emitted by the quark-gluon plasma (QGP) throughout its space-time evolution, with production rates that depend characteristically on the temperature. [...]

Interpolating amplitudes
/ Bresó, Víctor (U. Heidelberg, ITP) ; Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Magerya, Vitaly (CERN) ; Olsson, Anton (KIT, Karlsruhe, TP)
While the calculation of scattering amplitudes at higher orders in perturbation theory has reached a high degree of maturity, their usage to produce physical predictions within Monte Carlo programs is often hampered by the slow evaluation of the multi-loop amplitudes, especially so for amplitudes calculated numerically.
