Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Carlos Duaso Pueyo, Austin Joyce, Hayden Lee, Guilherme L. Pimentel | Summary: We extend the cosmological bootstrap to correlators involving massless particles with spin. In de Sitter space, these correlators are constrained both by symmetries and by locality. In particular, the de Sitter isometries become […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Shunsuke Maeda, Domenico Orlando, Susanne Reffert, Masataka Watanabe | Summary: We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in $SU(2)$ $mathcal{N}=2$ SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: J. P. Lees, V. Poireau, V. Tisserand, E. Grauges, A. Palano | Summary: We report on a precision measurement of the ratio ${cal R}_{taumu}^{Upsilon(3S)} = {cal B}(Upsilon(3S)totau^+tau^-)/{cal B}(Upsilon(3S)tomu^+mu^-)$ using data collected with the BaBar detector at the SLAC PEP-II $e^+e^-$ collider. The measurement is based on […]
Kavli Affiliate: Taizan Watari | First 5 Authors: Yuichi Enoki, Yotaro Sato, Taizan Watari, , | Summary: We showed that there is no SU(2) Witten anomaly in a large class of 4d N = 2 supersymmetric Heterotic string compactifications. The consistency conditions we consider are the modularity of the new supersymmetric index, the integrality of […]

Kavli Affiliate: Michael McDonald | First 5 Authors: Yu Qiu, Tamara Bogdanovic, Yuan Li, Michael McDonald, Brian R. McNamara | Summary: Galaxy clusters are the most massive collapsed structures in the universe whose potential wells are filled with hot, X-ray emitting intracluster medium. Observations however show that a significant number of clusters (the so-called cool-core […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: T. Daniel Brennan, Christian Ferko, Emil Martinec, Savdeep Sethi, | Summary: We show that the $T overline{T}$ deformation of two-dimensional quantum field theory on $mathrm{AdS}_2$ is well-defined and solvable at the quantum level. Flow equations for the energy spectrum and partition function are derived in analogy with […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: John P. Ahlers, Marshall C. Johnson, Keivan G Stassun, Knicole D. Colon, Jason W. Barnes | Summary: KELT-9 b is an ultra hot Jupiter transiting a rapidly rotating, oblate early-A-type star in a polar orbit. We model the effect of rapid stellar rotation on KELT-9 b’s […]
Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Stefano Andriolo, Tzu-Chen Huang, Toshifumi Noumi, Hirosi Ooguri, Gary Shiu | Summary: The axionic weak gravity conjecture predicts the existence of instantons whose actions are less than their charges in appropriate units. We show that the conjecture is satisfied for the axion-dilaton-gravity system if we assume duality […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Tian Qiu, Wenting Wang, Masahiro Takada, Naoki Yasuda, Željko Ivezić | Summary: We present proper motion measurements for more than $0.55$ million main-sequence stars, by comparing astrometric positions of matched stars between the multi-band imaging datasets from the Hyper Suprime-Cam (HSC) Survey and the SDSS Stripe 82.
