Nieuwe fysica in zeldzame beauty-vervallen

Eduard Simioni, promovendus aan het Nikhef, heeft in zijn onderzoek een methode ontwikkeld om met het LHCb experiment -via het meten van een bepaald vervalsproces- nieuwe fysica te bestuderen. Hij verdedigt zijn proefschrift maandag 1 maart 2010 aan de Vrije Universiteit Amsterdam.

The Standard Model of particle physics has established itself through an impressive series of successes at explaining a large variety of experimental observations and for its mathematical beauty. Despite of this, it is still affected by several theoretical and phenomenological problems which lead particle physicists to postulate the existence of New Physics beyond the Standard Model, accompanied by the existence of new, yet unobserved, particles.

New heavy particles could be observed directly or indirectly. Indirect contributions can change significantly the predicted branching ratio in certain processes. For those reasons and due to its precise theoretical prediction and simple signature, the branching ratio of Bs meson decaying into two muons is considered the “smoking gun” of New Physics. In his research Eduard Simioni describes a method to measure this branching ratio at the LHCb experiment. LHCb is one of the four experiments along the Large Hadron Collider at the European Center of Nuclear Research (CERN) in Geneve, which became operative in November 2009.
