EPJ ST Highlight - An overview of neutrinos and their interactions

A new summary of the study of neutrinos, and the ways in which they interact with regular matter, could inspire both new and senior neutrino researchers to open up new areas of investigation within the field.

The history of our understanding of neutrinos, from their astrophysical origins to their elusive interactions with matter, is full of surprises. Although we know that they are the second most abundant particles in the universe after photons, they are also the least well understood. In this special issue of EPJ ST, M. Sajjad Athar and S.K. Singh at Aligarh Muslim University present a short overview of the study of neutrinos, and the ways in which they interact with other forms of matter at mid-to-high energies.

Neutrinos are produced by a variety of astrophysical sources: including nuclear fusion in stellar cores, colossal supernova bursts, and decays of cosmic rays in Earth’s atmosphere. They can also be produced artificially by nuclear reactors and particle accelerators – allowing physicists to learn more about their intriguing properties. Yet since the particles carry no charge, and almost no mass, their interactions with other forms of matter are incredibly subtle – making them notoriously difficult to study.

The story of neutrino physics began in 1930, when Wolfgang Pauli proposed that a new family of particles would be needed to explain the conservation of certain values during nuclear reactions. Ever since, the story of neutrino research has continued to challenge our understanding of particle physics. Among the most intriguing mysteries is an effect named ‘neutrino oscillation’ – where the particles appear to spontaneously transition between three possible ‘flavours,’ as first observed by CERN’s Large Electron-Position Collider in 1989.

Explaining this behaviour will require the development of new physics beyond the Standard Model: which presents our best current descriptions of fundamental particles, and how they interact with each other. In the face of this challenge, Athar and Singh hope that this volume will benefit both students and young researchers, and senior researchers in neutrino physics, potentially helping to stimulate new ideas and areas of investigation.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
