Physics at LHC

Taking a closer look at LHC

Physics teachers in secondary schools usually mention the LHC or CERN only because of the enormous size of the accelerators and detectors used there, the number of scientists involved in their activities and also the necessary international scientific collaboration.

Impressive pictures of the accelerators and detectors are also shown. This is correct but clearly incomplete since there are other didactic possibilities to explore while talking about one of the most important scientific institutions in the world.

The aim of this Section is to introduce a few simple physical calculations about some phenomena that took place in  the LHC .

Keep in mind that we will consider the parameters corresponding to the initial start-up of the LHC, so they should be updated, if necessary, with the values corresponding to the specific moment we wish to evaluate.

They can be used in the classroom in order to stimulate the curiosity of students, to help them to understand those physical concepts, and as an example of the relationship between the ‘cold equations’ of physics on the blackboard and the exciting work in scientific research.

The calculations that you will be finding in this Section are adapted to the Physics of Secondary School and in most of the cases are only very simple approaches to the correct results.

If you find any mistake, please don't hesitate to let us know and we will try to correct as rapidly as possible.

If you wish for more specific information you must go to websites linked to CERN and its experiments, where you will obtain more complex and specific descriptions and data.
