Baryons are particles made of three quarks. The particles can exist in a ground state (J=1/2) and an excited state (J=3/2). The CDF experiment discovered the positively charged Sigma-sub-b and the ...
With the Cosmic Origins Spectrograph on Hubble, we are conducting UV spectroscopic studies of missing baryons in the intergalactic medium, quasar ionizing spectra, mass estimates of super-massive ...
