Pozivamo vas na predavanje koje će sutra, petak 11. listopada 2024. godine s početkom u 16:00 sati u učionici B3-47, održati dr. sc. Vladimir Tello, gostujući istraživač na International Centre for Theoretical Physics, Trieste.
Tema predavanja je A Path Towards Neutrino Mass: Left-Right Symmetry.
Summary:
For much of history, it was believed that the fundamental laws of nature were symmetric between left and right. However, this idea was shattered in 1956 with the discovery that the weak force is profoundly asymmetric, as only left-handed particles participate. This surprising result is central to the Standard Model, our current framework for understanding elementary particle interactions. Yet, the Standard Model makes one puzzling prediction: that neutrinos, the lightest and most elusive particles, should have zero mass, something experiments now prove to be false.
What if this left-right symmetry, rather than being absent, is only hidden in nature at a deeper level? This is the core idea behind the Left-Right Symmetric Theory, which long ago predicted the existence of non-zero neutrino mass well before experimental confirmation. This theory also gives rise to the seesaw mechanism, which explains why neutrino masses are so incredibly small. Recent work has shown that the Left-Right Symmetric Theory is as predictive for neutrino masses as the Standard Model is for electrons and quarks. Beyond neutrino masses, the theory points to a range of new phenomena currently being investigated at the Large Hadron Collider. Should these predictions be verified, it would profoundly reshape our understanding of nature’s fundamental symmetries.
Short biography:
I hold a PhD from SISSA, Trieste, and have pursued postdoctoral research at Ludwig Maximilian University in Munich, Germany, and the Gran Sasso Science Institute in L’Aquila, Italy. Currently, I am a visiting researcher at the International Centre for Theoretical Physics, Trieste, where I focus on beyond the Standard Model physics. My research interests include neutrino mass, left-right symmetry, lepton number and lepton flavour violation, dark matter, baryogenesis, and gravitational waves.
