| Super-soft bounds and Higher Spins EFTs | |
| Francesco Sgarlata, SISSA | |
| Event Type: Informal HEP Talk | |
| Time: 11:00 AM - 12:00 PM | |
| Location: 726 Broadway, 940, CCPP Seminar | |
| Abstract: Using analyticity properties of the S-matrix, I will derive a class of amplitudes’ constraints under the assumptions of a local, unitary and Lorentz-invariant theory. I will show that these bounds strongly constraint a wide class of Wilsonian Effective Field Theories also providing an upper bound on the physical cut-off. As interesting application, I will discuss their impact on massive higher-spins EFTs which turn out to be extremely weakly coupled and reduce to the free theory in the massless limit. | |
| Line Intensity Mapping | |
| Shengqi Yang, New York University | |
| Event Type: CCPP Brown Bag | |
| Time: 12:30 PM - 2:00 PM | |
| Location: 726 Broadway, 940, CCPP Seminar | |
| Abstract: Molecular and fine structure lines emitted from the cooling gas,
which hosts star formation, provide information about the environment of
galaxy evolution and are attracting attention in recent years. Line
intensity mapping (LIM) is a new promising technique for studying the three
dimensional unbiased line emission. To connect the physical properties of
the interstellar medium and the intergalactic medium to the forthcoming LIM
observations, we simulate a 2 square degree LIM mock light cone catalog
