The Discovery of the Higgs Boson at the LHC
Chapter 6 The Discovery of the Higgs Boson at the LHC Peter Jenni and Tejinder S. Virdee 6.1 Introduction and the Standard Model The standard model of particle physics (SM) is a theory that is based upon principles of great beauty and simplicity. The theory comprises the building blocks of visible matter, the fundamental fermions: quarks and leptons, and the fundamental bosons that mediate three of the four fundamental interactions; photons for electromag- netism, the W and Z bosons for the weak interaction and gluons for the strong interaction (Fig. 6.1). The SM provides a very successful description of the visible universe and has been verified in many experiments to a very high precision. It has an enormous range of applicability and validity. So far no significant deviations have been observed experimentally. The possibility of installing a proton-proton accelerator in the LEP tunnel, after the e+e− programme, was being discussed in the 1980’s. At the time there were many profound open questions in particle physics, and several are still present. In simple terms these are: what is the origin of mass i.e. how do fundamental particles acquire mass, and why do they have the masses that they have? Why is there more matter than anti-matter? What is dark matter? What is the path towards unification of all forces? Do we live in a world with more space-time dimensions than the familiar four? The LHC [1, 2] was conceived to address or shed light on these questions. P. Jenni CERN, Geneva, Switzerland Albert-Ludwigs University Freiburg, Freiburg im Breisgau, Germany T. -

2018 Edinburgh ( Scotland)
Newsletter nº 9 (2018) Edinburgh - Scotland 2018 Scotland hosted the 22th meeting on April 20th and 21st, in Edinburgh. The meeting was attended by the following participants: Austria, Belgium, Denmark, England, France, Greece, Italy, Netherlands, Portugal, Scotland, Switzerland and Tenerife. A PROFITABLE AND ENJOYABLE MEETING ETL works harder each year. For one and a half days, members from countries all around Europe shared experiences, thoughts and challenges: The first part of the meeting was, as usual, the short reports from each country. Despite some difficulties, toy libraries still are a strong reality in Europe with the national associations searching for new ways to operate and raise awareness for the importance of these spaces for childhood and communities; Small presentations were developed on 2 special themes: partnership between toy libraries and book libraries and profitable toy libraries; Small group discussions on “How will toy libraries look like in 10 years? New ways to stay attractive” were held and the results will be shared in the next pages. We received also two video messages from ITLA’s Board: one from the Presi- dent, Monica Juarez, and one from the Conference Organizer, Monica Stach, inviting everybody to the 15th International Toy Library Conference that will be held between 9th-15th July 2019 in South Africa. More than 20 members attended the meeting in Edinburgh HOW WILL TOY LIBRARIES LOOK LIKE IN 10 YEARS? NEW AVENUES TO STAY ATTRACTIVE This was the main theme discussed in 5 small groups in ETL’s meeting in Scotland. Toy libraries felt in recent years a decrease in the number of volunteers, in the fund- ing for this spaces and, overall, a decreased in the importance communities give to Play. -

Benedict XVI in the garden of the Basilica di Santa Maria degli angeli e dei Martiri with the statue of “Galilei Divine Man” donated to the Basilica by CCaSt of Beijing. he great Galileo said that God wrote the book of nature in the form of the language of mathematics. He was convinced that God has given us two tbooks: the book of Sacred Scripture and the book of nature. and the lan - guage of nature – this was his conviction – is mathematics, so it is a language of God, a language of the Creator. Encounter of His Holiness Benedict XVI with the Youth , St Peter’s Square, thursday, 6 april 2006. n the last century, man certainly made more progress – if not always in his knowledge of himself and of God, then certainly in his knowledge of the macro- Iand microcosms – than in the entire previous history of humanity. ... Scientists do not create the world; they learn about it and attempt to imitate it, following the laws and intelligibility that nature manifests to us. the scientist’s experience as a human being is therefore that of perceiving a constant, a law, a logos that he has not created but that he has instead observed: in fact, it leads us to admit the existence of an all-powerful Reason, which is other than that of man, and which sustains the world. -
