B anomalies: hopes, disillusions, and future prospects.
B anomalies: hopes, disillusions, and future prospects. Within the Standard Model (SM) the basic constituents of matter are the three “families” (two quarks and two leptons) with different quantum numbers, that completely determine the properties of these particles under the three fundamental forces relevant at the microscopic level (strong, weak and electromagnetic interactions). Ordinary matter

Departed giants of theoretical physics
Departed giants of theoretical physics July 23rd 2021 was a sad day for the world of theoretical physics, which witnessed the passing of three giants of the field: Steven Weinberg, Toshihide Maskawa and Miguel Virasoro. Weinberg and Maskawa were awarded Nobel Prizes for their contributions to the Standard Model of particle physics, while Virasoro was

The NNLO frontier
The NNLO frontier The potential of a post-LHC collider to explore for hints of new physics relies on technological advancements but also on theoretical developments that will allow very accurate background determinations. With a concensus growing for a lepton collider offering a wide range of precision Higgs and electroweak measurements it is important to consider

How Many Fundamental Constants Does It Take To Explain The Universe?
How Many Fundamental Constants Does It Take To Explain The Universe? At a fundamental level, our Universe is made of particles, forces, interactions, and the fabric of space and time. Spacetime forms the ever-evolving stage on which the play of the cosmos unfolds, while the particles are the players. They can bind together, collide, annihilate,

The rise of the axions!
The rise of the axions! Roberto Peccei and Helen Quinn worked together in developing what is today known as the Peccei-Quinn symmetry; a mechanism that addresses the strong CP-violation that consequently led to the invention of axions and inspired an intense experimental and theoretical programme for more than three decades. In this special issue dedicated

Searching for axions: old and new ideas
Searching for axions: old and new ideas QCD, the theory of strong interactions allows the violation of CP symmetry that would result in a non-zero value for the neutron electric dipole moment. Current measurements constrain the neutron EDM to be one trillionth of the size predicted by QCD (because of CP violation). This means that

Why is fundamental physics worth researching?
Why is fundamental physics worth researching? BROKEN IMAGE NOT MOVED (drupal url : https://ep-news.web.cern.ch//content/why-fundamental-physics-worth-researching) What’s the point of investing fortunes into answering questions in advanced physics? 100 years ago, we might have asked the same questions of Schroedinger, Bohr, Heisenberg, Dirac, and the other pioneers of the quantum revolution. After all — what’s the point

Searching for leptoquarks at the LHC
Searching for leptoquarks at the LHC Last month, Admir Greljo (University of Mainz) and Abdollah Mohammad (Kansas State University, US) during the Collider Cross Talk, gave a comprehensive overview of the theoretical and experimental aspects in leptoquarks searches. Leptoquarks are hypothetical particles that can turn quarks into leptons and vice versa and they can be

Interview with Kip Thorne
Interview with Kip Thorne Kip Thorne is one of the leading physicists working on Einstein's theory of relativity today. He has pioneered the scientific investigation of black holes in the universe. He was one of the founders of the LIGO project to detect gravitational waves and he has been one of the international team of

The Lifetime Frontier
The Lifetime Frontier It bear repeating that there must be physics Beyond the Standard Model (BSM). The triumphant discovery of the 125 GeV Higgs Boson sharpens the Hierarch Problem, with naturalness suggesting new particles at the TeV scale. A multitude of interlocking astrophysical and cosmological observations give us great confidence in the existence of BSM
