Description
In this work we explore the possibilities to obtain the values of the CollinsSoper kernel and the strong coupling constant offered by what so far is the highest order result ever achieved in perturbation theory, that is for the energy correlators in the back-to-back limit at $N^4LL+N^3LO$.
The cross-section was implemented within ARTEMIDE’s code, using the $\zeta$-prescription for the runnings needed to sum up the large logarithms.
In contrast to the perturbative computation, the experimental data avaliable is from several years ago, but we tried to consider, to the best of our knowledge, the largest set of points in the analysis, for which we had to deal with some issues that will be briefly discussed also in this talk.
Finally we will give our predictions for the measurement of this observable in Belle and FCC-ee.
