The Nobel Prize in Physics 2013 has been awarded to P.W. Higgs and F. Englert for the conception of a theoretical framework that contributes to the understanding of the origin of mass of subatomic particles. The mechanism (known as the Higgs mechanism) has been recently confirmed by the observation of the fundamental particle predicted (the so called Higgs boson) by the ATLAS and CMS experiments of the Large Hadron Collider at CERN, Geneva. Particle physicists all over the world, both theoreticians and experimentalists, have contributed to the result in the last thirty years, to say the least: in the present paper an account is given of this discovery, a milestone in the current understanding of the microcosm.

The Masses

The Large Hadron Collider (LHC) at CERN is the highest energy machine for particle physics research ever built. In the years 2010–2012 this accelerator has collided protons to a centre-mass-energy up to 8 TeV (note that 1 TeV corresponds to the energy of about 1000 protons at rest; the mass of one proton is about 1.67×10–24 g). The events delivered by the LHC have been collected and analysed by four apparatuses placed alongside this machine. The search for the Higgs boson predicted by the Standard Model and the search for new particles and fields beyond this theory represent the most important points of the scientific programme of the LHC. In July 2012, the international collaborations ATLAS and CMS, consisting of more than 3000 physicists, announced the discovery of a new neutral particle with a mass of about 125 GeV, whose physics properties are compatible, within present experimental and theoretical uncertainties, to the Higgs boson predicted by the Standard Model. This discovery represents a major milestone for particle physics, since it indicates that the hypothesized Higgs mechanism seems to be responsible for the masses of elementary particles, in particular W± and Z0 bosons, as well as fermions (leptons and quarks). The 2013 Physics Nobel Prize has been assigned to F. Englert and P. Higgs, ‘for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider’.

Enormous efforts at accelerators and experiments all around the world have gone into the search for the long-sought Higgs boson, postulated almost five decades ago. This search has culminated in the discovery of a Higgs-like particle by the ATLAS and CMS experiments at CERN's Large Hadron Collider in 2012. Instead of describing this widely celebrated discovery, in this article I will rather focus on earlier attempts to discover the Higgs boson, or to constrain the range of possible masses by interpreting precise data in the context of the Standard Model of particle physics. In particular, I will focus on the experimental efforts carried out during the last two decades, at the Large Electron Positron collider, CERN, Geneva, Switzerland, and the Tevatron collider, Fermilab, near Chicago, IL, USA.

AbstractIn July 2012 the ATLAS and CMS experiments announced the discovery of a Higgs boson, confirming the conjecture put forward in the 1960’s. This article briefly traces the history of the Brout-Englert-Higgs mechanism, its impact on the elucidation of the standard model, the design and construction of the ATLAS and CMS experiments, and finally the discovery of the Higgs boson. The article outlines some of the challenges faced during the construction of the Large Hadron Collider and its experiments, and their operation and performance. In particular, recent results relating to the properties and couplings of the Higgs boson will be discussed as well future prospects at the LHC.

On July 26, 1895, Pierre Curie and Maria Sklodowska were married.  On June 23, 1903, Maria presented her doctoral dissertation “Investigation of radioactive substances” at the Sorbonne, which described the results of hard work in previous years, including the isolation of new elements - polonium and radium. In the same 1903, Marie and Pierre Curie were awarded the Nobel Prize in Physics “in recognition of the exceptional services they rendered to science through the joint research of radiation phenomena discovered by Professor Henri Becquerel”. She became the first female - laureate and remained the only one until 1935, when her daughter Irene was awarded the Nobel Prize.  In 1911, Marie Curie received the Nobel Prize in Chemistry “for outstanding achievements in the development of chemistry: the discovery of the elements radium and polonium, the isolation of radium and the study of the nature and compounds of this remarkable element”. Marie Curie became the first and to date the only woman in the world -twice the Nobel Prize winner.  After many years, the proposal of Marie and Pierre Curie on the use of radium in medicine has been implemented at the present time. Studied and proved its effectiveness in the treatment of bone metastases of prostate cancer.  The merits of these scientists before the whole world can hardly be overestimated. Humanity gratefully keeps a good memory for great discoveries for the benefit of people.
