Plans for particle colliders and intriguing neutrino results
In this week’s episode of the Physics World Weekly podcast, Hamish Johnston discusses the future prospects for particle physics. Hamish reports back from the April Meeting of the American Physical Society in Denver, Colorado, where he spoke to Fermilab’s Vladimir Shiltsev about the process of selecting the next big European collider that could one day replace the LHC. Shiltsev is one of many particle physicists who gathered in Spain this week to discuss various proposals from the community, including the 100 km Future Circular Collider that some physicists want to build at CERN.
But particle physics is not all about colliders. Hamish also speaks to Alysia Marino and Eric Zimmerman of the University of Colorado about recent findings in neutrino physics. As well as explaining what we can learn from these ghostly particles, Marino and Zimmerman discuss intriguing results from the T2K neutrino experiment in Japan that could offer some clues to help solve the mystery of why the Universe contains more matter than antimatter.
