Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Guglielmo Coloretti, Wanqiang Liu, Mira Littmann, Ian Low | Summary: We consider 2-to-2 scatterings of Higgs bosons in a CP-conserving two-Higgs-doublet model (2HDM) and study the implication of maximizing the entanglement in the flavor space, where the two doublets $Phi_a$, $a=1,2$, can be viewed as […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Unnati Kashyap, Thomas J. Maccarone, Mason Ng, Eliot C. Pattie, Swati Ravi | Summary: We report the first X-ray polarimetric results of the neutron star (NS) low-mass X-ray binary (LMXB) Z-source GX 349+2 using the Imaging X-ray Polarimetry Explorer (IXPE). We discovered that the X-ray source […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Sung Hak Lim, Kohei Hayashi, Shun’ichi Horigome, Shigeki Matsumoto, Mihoko M. Nojiri | Summary: The kinematics of stars in dwarf spheroidal galaxies have been studied to understand the structure of dark matter halos. However, the kinematic information of these stars is often limited to celestial positions and […]
