The top quark is beautiful, pretty charming and still very strange (the ups and downs of the top mass)
Juan Fuster (IFIC, University of Valencia-CSIC)
DESY Auditorium, 16:45 h
The mass of elementary particles remains still as one of the open puzzles in Particle Physics covering a mass range over more than 12 orders of magnitude. This is approximately the difference between the size of the earth and a vegetal cell. A detailed understanding why neutrinos are so light or why the top quark is so heavy is still lacking. The exact determination of these mass values has direct impact on the validity of the Standard Model and its possible extensions. The accurate experimental measurement of these parameters is therefore of utmost importance. The present colloquium reviews the present situation of the top-quark mass and addresses its prospects for future measurements at the Large Hadron Collider and at new accelerators.
