A reanalysis of event shape distributions in electron-positron annihilation

Journal of High Energy Physics
Theoretical calculations for event shape observables are often determined by using the conventional scale setting; i.e. the procedure defined by setting the renormalization scale to the center-of-mass energy μ r = s $$ \sqrt{s} $$ and evaluating ...

Review of e+e− → π+π−η

EPJ Web of Conferences, 2018
In this talk we review the current experimental status of electron-positron annihilation into π+π-η as well as the theoretical models to describe the data. Application of the CVC hypothesis to get the τ- decay to π-π0η branching fraction is discussed and

Resummed Results for Hadron Collider Observables

EPJ Web of Conferences, 2016
Event shapes are invaluable QCD tools for theoretical calculations and experimental measurements. We revise the definition of these observables in e+e− annihilation and in hadron collisions, and give a review of the state-of-the-art results for their ...

Studies of stainless steel exposed to sandblasting

Nukleonika, 2015
The influence of sandblasting on surface and subsurface of stainless steel is investigated using variable energy positron beam (VEP), positron annihilation spectroscopy (PAS), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Samples
