Building an Efficient Cluster Cosmology Software Package for Modeling Cluster Counts and Lensing
M. Aguena, O. Alves, J. Annis +60
We introduce a software suite developed for galaxy cluster cosmological analysis with the Dark Energy Survey Data. Cosmological analyses based on galaxy cluster number counts and w…
Towards Fairness in Personalized Ads Using Impression Variance Aware Reinforcement Learning
Aditya Srinivas Timmaraju, Mehdi Mashayekhi, Mingliang Chen +9
Variances in ad impression outcomes across demographic groups are increasingly considered to be potentially indicative of algorithmic bias in personalized ads systems. While there…
Interactions of Particles with "Continuous Spin" Fields
Philip Schuster, Natalia Toro, Kevin Zhou
Powerful general arguments allow only a few families of long-range interactions, exemplified by gauge field theories of electromagnetism and gravity. However, all of these argument…
Towards UV-Models of Kinetic Mixing and Portal Matter III: Relating Portal Matter and R-H Neutrino Masses
Thomas G. Rizzo
The kinetic mixing (KM) of a dark photon (DP) with the familiar one of the Standard Model (SM) requires the existence of a new set of fields, called portal matter (PM), which carry…
A Liquid Xenon Positron Target Concept
Max Varverakis, Robert Holtzapple, Hiroki Fujii +1
Positron targets are a critical component of future Linear Colliders. Traditional targets are composed of high-Z metals that become brittle over time due to constant bombardment by…
Multifield Ultralight Dark Matter
Mateja Gosenca, Andrew Eberhardt, Yourong Wang +4
Ultralight dark matter (ULDM) is usually taken to be a single scalar field. Here we explore the possibility that ULDM consists of light scalar fields with only gravitational in…
