The Scale of Superpartner Masses and Electroweakino Searches at the High-Luminosity LHC

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Jia Liu, Navin McGinnis, Carlos E. M. Wagner, Xiao-Ping Wang, | Summary: Searches for weakly interacting particles is one of the main goals of the high luminosity LHC run. In this work we study the well motivated cases of electroweakinos with mostly Wino and Bino […]

Cosmology Intertwined IV: The Age of the Universe and its Curvature

Kavli Affiliate: Wendy Freedman | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in discriminating between different […]

Cosmology Intertwined III: $f σ_8$ and $S_8$

Kavli Affiliate: Daniel Holz | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: The standard $Lambda$ Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with the latest data analyses. While these anomalies […]

Cosmology Intertwined II: The Hubble Constant Tension

Kavli Affiliate: Daniel Holz | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: The current cosmological probes have provided a fantastic confirmation of the standard $Lambda$ Cold Dark Matter cosmological model, that has been constrained with unprecedented accuracy. However, with the increase of the experimental sensitivity […]

Demonstration of an amplitude filter cavity at gravitational-wave frequencies

Kavli Affiliate: Lee McCuller | First 5 Authors: Kentaro Komori, Dhruva Ganapathy, Chris Whittle, Lee McCuller, Lisa Barsotti | Summary: Quantum vacuum fluctuations fundamentally limit the precision of optical measurements, such as those in gravitational-wave detectors. Injection of conventional squeezed vacuum can be used to reduce quantum noise in the readout quadrature, but this reduction […]

Demonstration of an amplitude filter cavity at gravitational-wave frequencies

Kavli Affiliate: Lisa Barsotti | Summary:Quantum vacuum fluctuations fundamentally limit the precision of optical measurements, such as those in gravitational-wave detectors. Injection of conventional squeezed vacuum can be used to reduce quantum noise in the readout quadrature, but this reduction is at the cost of increasing noise in the orthogonal quadrature. For detectors near the […]
