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: Wayne Hu | First 5 Authors: Tanisha Jhaveri, Tanvi Karwal, Wayne Hu, , | Summary: Under $Lambda$CDM, recent baryon acoustic oscillation (BAO) distance measures from DESI, which favor a low matter density $Omega_m$, are in moderate $2-3sigma$ tension with cosmic microwave background (CMB) observations. This tension appears alternately as a preference for the […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Nickolay Y. Gnedin, , , | Summary: We investigate the properties of cosmological ionization fronts during the Epoch of Reionization using the CROC simulations. By analyzing reionization timing maps, we characterize ionization front velocities and curvatures and their dependence on the density structure of […]
Kavli Affiliate: Bradford A. Benson | First 5 Authors: Frank J. Qu, Fei Ge, W. L. Kimmy Wu, Irene Abril-Cabezas, Mathew S. Madhavacheril | Summary: We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Telescope (ACT), the South […]

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Aurora Ireland, Tong Ou, Isaac R. Wang, | Summary: A precise determination of the bubble wall velocity $v_w$ is crucial for making accurate predictions of the baryon asymmetry and gravitational wave (GW) signals in models of electroweak baryogenesis (EWBG). Working in the local thermal equilibrium […]
Kavli Affiliate: Clarence Chang | First 5 Authors: Clarence Chang, T. J. Hobbs, Dafei Jin, Yi Li, Marharyta Lisovenko | Summary: We introduce an array-scalable, magnon-based detector (MOSAIC) to search for the spin-dependent interactions of electron-coupled axion dark matter. These axions can excite single magnons in magnetic targets, such as the yttrium iron garnet (YIG) […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Harry Goodhew, Austin Joyce, Hayden Lee, Guilherme L. Pimentel | Summary: We uncover a geometric organization of the differential equations for the wavefunction coefficients of conformally coupled scalars in power-law cosmologies. To do this, we introduce a basis of functions inspired by a decomposition of […]
