DESCRIPTION:Speakers: Mr. MARKIEWICZ\, Adam (University of Warsaw)\nDynami
 c relaxation provides an interesting framework which intends to solve the 
 hierarchy problem by postulating\, that the observed value of the electrow
 eak scale was determined dynamically in the early Universe. Values of the 
 electroweak scale were scanned during an evolution of axion-like field (a 
 relaxion)\, with a stopping mechanism responsible for fixing the scale at 
 a small value. \n\nThe original relaxation proposal depended on an ongoing
  inflation\, putting significant constraints on the inflationary sector. S
 ince then alternative variants of relaxation were proposed\, which allow t
 o decouple it from inflation completely. In these scenarios relaxation is 
 stopped though a burst of particle production which happens when the relax
 ion enters a non-adiabatic region. \n\nQualitative and analytical approach
  can tell us a lot about the viability of such relaxation models. It is ho
 wever still interesting to track the relaxation process in detail\, which 
 can only be done numerically. In this talk we will present our work toward
 s such analysis done with a goal of investigating a subtle interplay betwe
 en the relaxion\, the electroweak scale\, and the produced particles.\n\nh
