Status of the BeEST Heavy Neutrino Search Experiment
Speaker: Inwook Kim (Lawrence Livermore National Laboratory)Host: Doojin Kim
The Beryllium Electron-capture in Superconducting Tunnel junctions (BeEST) experiment aims to detect the signatures of heavy neutrino mass eigenstates by meticulously measuring the recoil energy of the Li-7 daughter nucleus resulting from Be-7 electron capture. Operating a single uperconducting tunnel junction (STJ) detector, the BeEST has set world-leading limits on [...]
Gravitational Waves from Nnaturalness
Speaker: Mudit Rai (Texas A&M University)Host: Doojin Kim
In this work, we investigate the gravitational wave aspect of the Nnaturalness models. They have been previously well studied in the context of higgs hierarchy problem. We find that Nnaturalness by itself cannot explain the recent observation of stochastic GW background observed recently by NANOGrav. However a large chunk of [...]Compositeness from eV to TeV
Speaker: Benoît Assi (Fermilab)Host: Doojin Kim
Composite states occur over vast scales and play an important role in various domains of particle physics. In the first part I report on the recent development and application of non-relativistic QCD for the study of hadrons and multi-hadron systems in QCD and beyond. In particular, I will demonstrate how we [...]
