The Higgs Boson - a Dissection Tool for New Physics

Sala de Seminários do LIP (com transmissão via Zoom)

Por Margarete Mühlleitner (Institute for Theoretical Physics, Karlsruhe Institute of Technology)​.

The discovery of the Higgs boson in 2012 by the LHC experiments ATLAS and CMS at the Large Hadron Collider marked a milestone for elementary particle physics. In the meantime the properties of the discovered Higgs boson have been investigated, and the Higgs turns out to behave very Standard Model (SM)-like. The SM of particle physics furthermore has been tested to great accuracy at the quantum level. However, there are open questions like e.g. the nature of Dark Matter or why there is more matter than antimatter in the Universe, that cannot be answered by the SM. This calls for new physics beyond the SM. So far unfortunately, we do not have any direct sign of new physics. In this situation the role of the Higgs boson becomes extremely important as a dissection tool in our search for physics beyond the SM. I will highlight in my talk the special role of the Higgs boson for our understanding of the true model underlying particle physics. I will present selected examples that demonstrate what can be learnt from the Higgs boson on physics beyond the SM and how it may guide our way in our quest for the model that allows us to describe nature and help us to understand the true picture behind it.

The objective of this course is to acquire knowledge regarding bioinformatic tools available to predict nucleic acid (RNA, DNA or Nucleic Acids Mimics) and protein three-dimensional structure, as well as autonomy and critical thinking in the use of those tools.

Science is increasingly more present in our everyday decisions, with a fundamental role in global problems. Scientists, as the main actors in the production of scientific knowledge, have the responsibility of having an active voice in communicating this knowledge.

The course aims at introducing attendants to an updated state of the art of diversity of the soil biota and the functional roles played by soil organisms in key ecological processes.

Symbiosis is a key strategy for life on Earth. Nevertheless, although many research groups have long been committed to the study of symbiosis, its definition and functioning are not fully understood, and its ecological role and relevance are still underestimated.

This 5-day course offers to the participants a light microscopy course focusing on fluorescence microscopy techniques applied to the detection of proteins and glycans in tissue samples and cell cultures.
