Reference excerpt

Gian Francesco Giudice (born 25 January 1961) is an Italian theoretical physicist working at CERN in particle physics and cosmology.

Academic career After graduating in physics from the University of Padua in 1984, Giudice obtained in 1988 his PhD in theoretical physics from the International School for Advanced Studies in Trieste. Between 1988 and 1990, he was a Research Associate at the Fermi National Accelerator Laboratory near Chicago. Between 1990 and 1992, he was a Research Fellow in the Physics Department of the University of Texas at Austin, in the group led by Steven Weinberg. After being employed by the Istituto Nazionale di Fisica Nucleare of Italy, in 1993 he moved to CERN, where he is currently the Head of the Theoretical Physics Department. Academician of the Accademia dei Lincei, the Istituto Veneto di Scienze, Lettere ed Arti, and Accademia Galileiana, he has been awarded the Jacques Solvay Chair in Physics at the Université libre de Bruxelles (2013), Distinguished Visiting Research Chair at Perimeter Institute for Theoretical Physics (2019), Sackler Distinguished Lecturer at Tel Aviv University (2020), Chandrasekhar Lecturer at Tata Institute of Fundamental Research (2022), Erwin-Schrödinger Professor at the University of Vienna (2023).

Research The research activity of Giudice mainly deals with the formulation of new theories that extend our present knowledge of the particle world toward smaller distances. He is also studying how these theories can be applied to cosmology in order to describe the early stages of the history of our universe. His most notable results are in the areas of supersymmetry, extra dimensions, electroweak physics, collider physics, dark matter, and leptogenesis. Together with physicist Riccardo Barbieri, he proposed a widely used criterion to test the degree of naturalness of a supersymmetric theory that achieves electroweak symmetry breaking. He co-invented the Giudice-Masiero mechanism, which is the leading explanation for the mu problem of supergravity. He has made fundamental contributions to the construction of Gauge Mediation, and he is a co-author of the first papers proposing Anomaly Mediation and Split Supersymmetry. He is one of the proponents of a method to compute quantum effects in theories with broken supersymmetry through analytic continuation into superspace. Well-known and much used in LHC studies is his method to describe graviton interactions in theories with extra spatial dimensions. He is also one of the originators of the idea of Minimal Flavor Violation, a paradigm to characterize the effects of flavor transitions in new theories of particle physics. After the discovery of the Higgs boson, he computed the probability that the Higgs vacuum undergoes quantum tunnelling, finding the surprising result that the universe is in a critical state which will eventually end in a cosmic collapse.

Support of particle accelerator projects Giudice has played an active role in studying the physics potential of particle accelerators, supporting and advocating several new projects at CERN and in other laboratories worldwide. He has been a member of the LHC Experiments Committee (the body that reviews the activity of the experimental groups at the LHC), the European Committee for Future Accelerators (the advisory body for long-range planning of high-energy facilities in Europe), the preparatory group for the 2020 European Strategy for Particle Physics, and numerous advisory and review committees of research institutes worldwide.

Science popularization Besides his research work, Giudice is active in popularization of science and outreach, often giving public lectures on particle physics and related topics, and participating in science festivals and other events. He is the author of A Zeptospace Odyssey, a popular-science book on the physics of the LHC, which has been finalist for the 2012 Galileo Literary Prize for popular science and the Prize Pianeta Galileo 2013. The book, originally written in English, has been translated into Italian, German, French, Spanish, and Korean.

Worked examples

Example 1 — a first encounter with Gian Francesco Giudice

Start with the simplest possible case. Write down what Gian Francesco Giudice claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gian Francesco Giudice before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gian Francesco Giudice ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gian Francesco Giudice

In research: Gian Francesco Giudice appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Gian Francesco Giudice in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Gian Francesco Giudice is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, 20th-century Italian physicists, 21st-century Italian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Gian Francesco Giudice outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
