International KEK-Cosmo and APCosPA Winter School 2019, “Primordial Black Hole” 22nd — 24th January 2019 Theory Center, IPNS, KEK, Oho 1-1, Tsukuba 305-0801, Japan

After aLIGO detected the gravitational wave (GW) produced by mergers
of binary black holes (BHs), researchers have aggressively studied the
origin of the BHs with masses of the order of O(10) solar mass. In
addition to astrophysical origins of BHs, one of the attractive
candidates of those massive BHs should be Primordial Black Holes
(PBHs), which were produced in the early Universe, e.g., through
collapses of large curvature perturbation at small scales produced by
inflation, not through normal collapsing stars. In addition to the
candidates of the sources for the GW events, it is exciting that PBHs
can be also whole or in part of dark matter. Therefore, nowadays PBHs
have become common topics to be studied in astrophysics, cosmology and
particle physics.

So far a variety of researches on PBHs have been reported within a
couple of years. For students and young postdocs, it should have been
a challenging task to catch up with recent topics related with
PBHs. Therefore, we organize this school to study the current status
of PBHs.

We ask each lecturer to cover both basic topics and cutting-edge
researches. The number of audiences will be restricted due to the
limited size of lecture rooms. The lecturers can use white boards as
well as projectors, although we may ask the lecturers to mainly give
white-board lectures, as these are easier for audiences to digest, in
particular with regard to equations.

Topics to be discussed:
Mechanisms for Formations of PBHs
Cosmological scenarios to produce PBHs
Observational constraints on PBHs
Astrophysical Black Holes

Invited speakers include:
Tomohiro Harada (Rikkyo U, Japan), “Mechanisms for Formations of PBHs”
Teruaki Suyama (Tokyo Tech, Japan), “Cosmological formation rates of
binary PBHs”
Ryuichi Takahashi (Hirosaki U, Japan), “Gravitational Lensing and BHs”
Kohei Inayoshi (Columbia U, USA), “Pop.III / II stars and binary BH

KEK-PH 2018 winter & 3rd KIAS-NCTS-KEK Joint Workshop

The annual Theory Meeting on Particle Physics Phenomenology (KEK-­PH2018) together with the 3rd KIAS-NCTS-KEK Joint Workshop will be held at KEK between December 4 – 7, 2018. This meeting covers many topics in Particle Physics and Cosmology, from the Standard Model and models beyond the Standard Model to particle cosmology and astrophysics. We plan to discuss recent developments in modeling Physics Beyond the Standard Model with their phenomenological aspects and also learn about the latest results and status of various ongoing and planned experiments.
