The determination of the strong coupling constant from event-shape observables remains a central topic in precision QCD. 

Among these observables, thrust has long played a central role: it is comparatively simple, well studied, and continues to serve as a benchmark for precision determinations of the strong coupling constant.

This dedicated workshop is intended as the first in a series of focused meetings aimed at addressing the key open questions in α_s determinations from thrust.This November meeting will focus on the following aspects:

• Impact of the choice of resummation space

• Data systematic uncertainties and the recent ALEPH data reanalysis

• Hadron mass effects and mass schemes

• Impact of 3-jet power corrections

The workshop’s format will consist of short technical introductions followed by extended time for discussion. The emphasis is on interaction and collaborative problem-solving rather than on formal presentations.
