Primordial Black Holes Place the Universe in Stasis
Keith R. Dienes, Lucien Heurtier, Fei Huang +3
A variety of scenarios for early-universe cosmology give rise to a population of primordial black holes (PBHs) with a broad spectrum of masses. The evaporation of PBHs in such scen…
Primordial Black Holes and their Mass Spectra: The Effects of Mergers and Accretion within Stasis Cosmologies
Keith R. Dienes, Lucien Heurtier, Fei Huang +2
A variety of processes in the very early universe can give rise to a population of primordial black holes (PBHs) with an extended mass spectrum. For certain mass spectra of this so…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
MATHUSLA: An External Long-Lived Particle Detector to Maximize the Discovery Potential of the HL-LHC
Branden Aitken, Cristiano Alpigiani, Juan Carlos Arteaga-Velázquez +70
We present the current status of the MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles) long-lived particle (LLP) detector at the HL-LHC, covering the design, f…
Conceptual Design Report for the MATHUSLA Long-Lived Particle Detector near CMS
Branden Aitken, Cristiano Alpigiani, Juan Carlos Arteaga-Velázquez +70
We present the Conceptual Design Report (CDR) for the MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles) long-lived particle detector at the HL-LHC, covering th…
Spotting Stasis in Cosmological Perturbations
Keith R. Dienes, Lucien Heurtier, Daniel Hoover +3
As discussed in a number of recent papers, cosmological stasis is a phenomenon wherein the abundances of multiple cosmological energy components with different equations of state r…
