DESCRIPTION:Oriented event-shapes are distributions of event-shape variabl
 es which are differential on the angle that the thrust axis forms with the
  electron-positron beam. We analyze these distributions in the context of 
 SCET and in Fixed-Order perturbation theory. We show that at any order in 
 perturbation theory and for any event-shape\, only two angular structures 
 can appear. The validity of our proof goes beyond perturbation theory\, an
 d hence only these two structures are present at the hadron level. The pro
 of also carries over massive particles. Using SCET techniques we show that
  singular terms can only arise in one of these two terms.\n\nhttps://indic
