SUMMARY:Future cosmology with CMB lensing and galaxy clustering\, Theo
 ry Seminar (High Energy/Cosmology)\, Marcel Schmittfull\, Institute fo
 r Advanced Study
DESCRIPTION:Next-generation Cosmic Microwave Background experiments su
 ch as the Simons Observatory\, CMB-S4 and PICO aim to measure gravitat
 ional lensing of the Cosmic Microwave Background an order of magnitude
  better than current experiments. The lensing signal will be highly co
 rrelated with measurements of galaxy clustering from next-generation g
 alaxy surveys such as LSST. This will help us understand whether cosmi
 c inflation was driven by a single field or by multiple fields. It wil
 l also allow us to accurately measure the growth of structure as a fun
 ction of time\, which is a powerful probe of dark energy and the sum o
 f neutrino masses. I will discuss the prospects for this\, as well as 
 recent progress on the theoretical modeling of galaxy clustering\, whi
 ch is key to realize the full potential of these anticipated datasets.
