520. Overview of the T2K experiment

Grzegorz Żarnecki (Polska Akademia Nauk, Instytut Fizyki Jądrowej im. Henryka Niewodniczańskiego)

Plenary

T2K is a long baseline neutrino experiment in Japan producing a beam of (anti-)neutrinos at an accelerator complex and studying their oscillations by comparing the measured (anti-)neutrino spectrum at the near detector ND280 and at the water Cherenkov detector Super Kamiokande (Super-K), located 295 km away. Over the recent years, significant updates were applied to the T2K oscillation...

470. Axion-Induced Patchy Screening of the CMB

Cristina Mondino (Perimeter Institute for Theoretical Physics)

Plenary

Cosmic Microwave Background (CMB) photons can undergo resonant conversion into axions in the presence of magnetized plasma distributed inside non-linear Large-Scale Structure (LSS). This process leads to axion-induced patchy screening: secondary temperature and polarization anisotropies with a characteristic non-blackbody frequency dependence that are strongly correlated with the distribution...

540. Beyond the Standard Model in the Higgs sector

Adriana Milic (CERN)

Plenary

The discovery of the Higgs boson with the mass of about 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable to solely explain some observations. Many extensions of the Standard Model addressing such shortcomings introduce additional Higgs bosons, beyond-the-Standard-Model...
