KEK-Cosmo 2017 Workshop

Fundamental Physics in the Universe

20th — 22nd February 2017

Theory Center, KEK, Tsukuba, Japan



Experiments at the Large Hadron Collider (LHC) of CERN have revealed the existence of the Higgs boson. This discovery marks the completion of the Standard Model (SM) of particle physics, making the search for theories beyond the SM more compelling than ever. Notably, the need for such extensions is linked to the failure of the SM to explain a number of astrophysical and cosmological observations: 1) the origin of matter-antimatter asymmetry, 2) the origin of neutrino masses, 3) the nature of dark matter, 4) the nature of the inflaton field, and 5) the nature of dark energy. In addition, quite recently "the Higgs stabilization problem” has been identified: fluctuations of the Higgs field produced during the cosmic evolution may destabilize the Higgs field itself.


In order to elucidate the above issues, interdisciplinary research combining elements of particle physics, astrophysics and cosmology will be of great importance. In this school, we invite experts of research in these fields and ask them to give a series of lectures.


We ask each lecturer to cover both basic topics and cutting-edge research. The audience will be fewer than 30 people 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 audience members to digest, in particular with regard to equations.

l  Cosmological perturbations and future observations

l  New physics in neutrino cosmology

l  Dark matter and future experiments

l  Gravitational wave
