Which of the following problems is "harder" to solve? Adding two 5-digit numbers or multiplying them? In general, it seems that multiplying is harder, but is there a way to make this feeling formal?
The area of theoretical computer science tries to do just that for any given problem! In this talk, we will look at some examples of such problems and try to see how easy/hard it is to solve them.
The Future Circular Collider program is profiling itself as the next big challenge taken up by CERN. This ambitious program would be a unique opportunity to fuel the field of high-energy physics for several decades to come. Be it for testing the standard model predictions with unprecedented precision or to search for new particles, this machine isbeing designed with versatility and diversity at the heart of its multi-stage program. This presentation will aim at providing a snapshot at the current state of affairs. Emphasis will be given on the physics case, particularly for the FCC-ee early stage
