DESCRIPTION:\nThe existence of new mechanisms of CP violation is one of th
 e necessary conditions to explain the matter-antimatter asymmetry in the U
 niverse. Searches for new mechanisms of CP (or T)-violation are being carr
 ied out in precision measurements of electric dipole moments of particles\
 , nuclei\, atoms\, and molecules as well as in properly selected correlati
 ons in decay processes. Positronium (Ps) is a purely leptonic state that d
 ecays into photons. The observation of a CP violating correlation associat
 ed with the decay process\, at the current level of sensitivity\, would pr
 ovide a signature of physics beyond the Standard Model. A CP violating cor
 relation can be formed in Ps decay\, involving the tensor polarization and
  the momenta of the two highest energy photons in the three-photon decay o
 f ortho-Ps. We have designed and built a new apparatus to search for CP-vi
 olation in ortho-Ps decay with an order of magnitude improved sensitivity 
 relative to previous work. This talk will present the driving elements for
  its design and optimization\, which includes a photon detector array and 
 the Ps formation medium and will discuss the improved sensitivity of the d
 esign.\n\n\n\nhttps://indico.ific.uv.es/event/8574/
