Special Issue Information

Dear Colleagues, 

In this Special Issue, selected papers from the International Conference on Precision Physics and Fundamental Physical Constants (FFK 2023, https://indico.cern.ch/event/1164804/, 22‒26 May 2023) are presented. FFK 2023 followed the rich traditions of the previous seminars and conferences, covering the recent progress in the field.

The presentations spanned a wide range of topics, from classical metrology; the realisation of the kilogramme, through precision spectroscopy of electronic and exotic atoms; as well as molecules to determine masses and magnetic moments of elementary particles; electric dipole measurements; and mass measurements to particle physics aspects such as precision measurements of the neutron, the CKM matrix, recent developments in the theory of muon g‒2, and collider searches for beyond-the-standard-model physics.

FFK 2023 was endorsed by CODATA Task group on fundamental constants.

Although this Special Issue collaborates with the International Conference on Precision Physics and Fundamental Physical Constants (FFK 2023), all relevant manuscripts are welcome, including research and review articles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Physics is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We, the QUARTET Collaboration, propose an experiment to measure the nuclear charge radii of light elements with up to 20 times higher accuracy. These are essential both for understanding nuclear physics at low energies, and for experimental and theoretical applications in simple atomic systems. Such comparisons advance the understanding of bound-state quantum electrodynamics and are useful for searching for new physics beyond the Standard Model. The energy levels of muonic atoms are highly susceptible to nuclear structure, especially to the mean square charge radius. The radii of the lightest nuclei (with the atomic number, Z=1,2) have been determined with high accuracy using laser spectroscopy in muonic atoms, while those of medium mass and above were determined using X-ray spectroscopy with semiconductor detectors. In this communication, we present a new experiment, aiming to obtain precision measurements of the radii of light nuclei 3Z10 using single-photon energy measurements with cryogenic microcalorimeters; a quantum-sensing technology capable of high efficiency with outstanding resolution for low-energy X-rays.
