The Physics Department High Energy Theory Group of the Brookhaven National Laboratory has a two-year term opening for an Assistant Physicist with a strong record of research accomplishments in Particle Physics Phenomenology, broadly defined.
A recent analysis done by A.Donini et. al [1] measures the density profile of the Earth using atmospheric neutrinos.
Even though neutrinos are weakly interacting particles, cosmic rays scattering with the nuclei of the atmosphere produce a high energetic neutrino flux with a non-negligible probability to interact with the nucleons of the Earth, when passing through it. Using a one-year muon data set measured by the IceCube neutrino telescope [2], it is possible to infer the Earth’s density profile. This method provides a new way to study Earth’s internal structure and although the idea is not new, this work represents the first attempt at applying it using actual data. This is the first time we can actually see the interior of the Earth by means of neutrino tomography and obtain non-trivial results.
Rachel Houtz recently wrote an article for El País. She explains for the general public how a recent precision measurement of the fine-structure constant restricts dark photon parameters space. The article appeared on the El País website on April 18, 2018.
Andrea Caputo first introduced the Standard Model, talking about particles, interactions and the role of LHC. Sam Witte then specialized on Dark Matter and Arsenii Titov on Neutrinos, focusing on conceptual, historical and also experimental aspects, highlighting the role of Hamamatsu products in some experiments like XMASS and Hyper-Kamiokande.
