The search for the Higgs boson at the LHC.

Abstract

One of the main goals of the Large Hadron Collider (LHC) is to search for evidence of the illustrous Higgs boson. This particle, although never seen, is one of the vital ingredients in the formulation of the Standard Model of elementary particles. It is at the heart of our current understanding of electroweak symmetry breaking and allows for masses for the gauge bosons and fermions. In 2011 the experiments at the Large Hadron collider (LHC) have collected and analysed a large amount of proton-proton collission at a centre-of-mass energy of 7 TeV. At the end of 2011 the CMS and ATLAS experiments have presented their results in this endeavour, hinting to a possibel excess of data compatible with the Higgs boson, but unable to provide a definite yes/no answer to it's existence. I will give an overview of the search for the Higgs boson, discuss the current results in detail and will hopefully convince you that the discovery, or exclusion of the Higgs boson is only a few months away.


The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the main auditorium of the Oort building. Before the Colloquium, there is a common dinner in the canteen located on the ground floor of the Oort building. This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium.

The registration form is only accessible from within the University (to block spammers); if you would like to register for the dinner from outside the University, please send an email to fran@lorentz.leidenuniv.nl

After 6 pm the revolving doors of the Oort building, approached by the long bridge alongside the Kamerlingh Onnes Laboratory, are locked and one should instead use the sliding doors directly adjacent to the Huygens building: these can be opened with an electronic key (seek help from locals).
