Light long-lived particles at the FCC-hh with the proposal for a dedicated forward detector FOREHUNT and a transverse detector DELIGHT

Posted by dbos June 20, 2023Tokyo

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Biplob Bhattacherjee, Herbi K. Dreiner, Nivedita Ghosh, Shigeki Matsumoto, Rhitaja Sengupta | Summary: In this paper, we propose a dedicated forward detector, FOREHUNT (FORward~Experiment~for~HUNdred~TeV), for 100 TeV FCC-hh for the detection of light long-lived particles (LLP) coming from $B$-meson decay. We calculate the signal acceptance as a […]

A calibration point for stellar evolution from massive star asteroseismology

Posted by dbos June 20, 2023MIT

Kavli Affiliate: George Ricker | First 5 Authors: Siemen Burssens, Dominic M. Bowman, Mathias Michielsen, Sergio Simón-Díaz, Conny Aerts | Summary: Massive stars are progenitors of supernovae, neutron stars and black holes. During the hydrogen-core burning phase their convective cores are the prime drivers of their evolution, but inferences of core masses are subject to […]

A Hunt for Magnetic Signatures of Hidden-Photon and Axion Dark Matter in the Wilderness

Posted by klaurent June 20, 2023Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Ibrahim A. Sulai, Saarik Kalia, Ariel Arza, Itay M. Bloch, Eduardo Castro Muñoz | Summary: Earth can act as a transducer to convert ultralight bosonic dark matter (axions and hidden photons) into an oscillating magnetic field with a characteristic pattern across its surface. Here we describe […]

The Cosmic Ultraviolet Baryon Survey (CUBS) VI: Connecting Physical Properties of the Cool Circumgalactic Medium to Galaxies at $zapprox 1$

Posted by klaurent June 20, 2023MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Zhijie Qu, Hsiao-Wen Chen, Gwen C. Rudie, Sean D. Johnson, Fakhri S. Zahedy | Summary: This paper presents a new sample of 19 unique galaxies and galaxy groups at $zapprox1$ from the CUBS program, which is designated as the CUBSz1 sample. In this CUBSz1 sample, nine […]
