Modern cosmology has in recent years established itself as a competitive and complementary probe of particle and fundamental physics.Thanks to the precise measurement of the cosmic microwave background (CMB) temperature and polarization anisotropies by Planck, BICEP 2 and other experiments, the new large scale structure (LSS) data from the SDSS, WISE, PanSTARRS, and DES surveys, our understanding of the main constituents of Universe has gone through a significant improvement. The accurate determination of the power spectrum of primordial perturbations, the tight constraints on primordial non-gaussianities and isocurvature initial conditions put to severe test all models of early universe cosmology.
From the side of particle and astro-particle physics,we are eagerly waiting for the next LHC measurements of the Higgs sector. There are many new direct and indirect dark matter searches, and there has been further understanding of neutrino properties.These data will sharpen the theoretical description of dark matter. This data will be useful both for particle physics beyond the Standard Model, for example for string theory phenomenology, and it will also be relevant for the emergent class of slow-roll inflationary models which provide a better fit to CMB anisotropies data.
The avalanche of experimental results and observations will have implications for both fundamental physics and for cosmology. The $\Lambda$CDM cosmological model provides a good fit to a host of observations, but at present puzzles persist about the consistency with observations of galaxies and galaxy clusters, and there are CMB anomalies on large angular scales, to name only a few observational challenges to the current paradigm. There are glaring mysteries concerning the origin of the articular parameter values in cosmology, in particular the value of the density of dark energy. Current and future cosmological data allow us to scrutinize in depth new physics beyond the $\Lambda$CDM cosmological model,such as models of dark energy, dark radiation, modified gravity and variation of the fundamental constants. The data also allows us to explore particle physics beyond the Standard Model.
The programme will bring together leading cosmologists and particle physicists from all over the world and provide a lively environment for a fruitful exchange of ideas. Participants and short-term visitors will be selected from both inside and outside China. In particular, we aim to make this workshop as an opportunity to sharpen the profile of fundamental research in China.
