  • KIAS Particle Physics journal club meetings are held every Friday, unless notified otherwise.

  • At each meeting, two presenters introduce one or more recent papers, for an allotted time of around 30 minutes each.

  • After the presentations, the speakers for the subsequent meeting are prompted. Their selection generally follows the order in the list on this site.

  • The current organizer is Suro Kim(Contact : surokim@kias.re.kr).

Attendees can sign up for their lunch boxes via the doodle link prepared by the organizer by 18:00 on the Thursday prior.

Title : Primordial black hole formation by bubble collisions in first-order phase transitions

Abstract : Various new physics models can be tested via primordial black hole searches as well as the primordial black hole itself is a good dark matter candidate. In this talk, I will shortly introduce some primordial black hole formation mechanisms in cosmological first-order phase transitions and will focus on the mechanism where primordial black holes are formed by bubble collisions. For this mechanism to work, symmetry-breaking bubbles need to be larger than the Hubble radius and not run-away. The PBH abundance can be estimated by counting the number of such collisions of large bubbles for a given first-order phase transition.
