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 […]

Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle

Kavli Affiliate: Saul Rappaport | First 5 Authors: Maximilian N. Günther, David A. Berardo, Elsa Ducrot, Catriona A. Murray, Keivan G. Stassun | Summary: New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 and TESS data. All of these targets are part of young […]

Probing galaxy evolution in massive clusters using ACT and DES: splashback as a cosmic clock

Kavli Affiliate: Eli Rykoff | First 5 Authors: Susmita Adhikari, Tae-hyeon Shin, Bhuvnesh Jain, Matt Hilton, Eric Baxter | Summary: We measure the projected number density profiles of galaxies and the splashback feature in clusters selected by the Sunyaev–Zeldovich (SZ) effect from the Advanced Atacama Cosmology Telescope (AdvACT) survey using galaxies observed by the Dark […]

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 […]
