The Standard Model (SM), the main physics framework describing elementary particles and the forces driving them, outlines key patterns in physical interactions referred to as gauge symmetries. One of the symmetries it describes is the so-called U(1)Y hypercharge:...

Study unveils new extrusion-induced instabilities in viscoelastic materials
Soft viscoelastic solids are flexible materials that can return to their original shape after being stretched. Due to the unique properties driving their deformation, these materials can sometimes behave and change shape in unexpected ways.
The ALPHA experiment moves towards the increasingly precise study of antihydrogen
Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal matter counterparts, yet they exhibit an opposite charge and distinct quantum properties.
NEON experiment shares results from first direct search for light dark matter
Detecting dark matter, the elusive type of matter predicted to account for most of the universe's mass, has so far proved to be very challenging. While physicists have not yet been able to determine what exactly this matter consists of, various large-scale experiments...
Nickel-58 nucleus may host elusive toroidal dipole excitations
Dipole toroidal modes are a unique set of excitations that are predicted to occur in various physical systems, ranging from atomic nuclei to metamaterials. What characterizes these excitations, or modes, is a toroidal distribution of currents, which results in the...
Active particles reorganize 3D gels into denser porous structures, study shows
Colloidal gels are complex systems made up of microscopic particles dispersed in a liquid, ultimately producing a semi-solid network. These materials have unique and advantageous properties that can be tuned using external forces, which have been the focus of various...
The first search for soft unclustered energy patterns in proton–proton collisions at 13TeV
A key objective of many physics studies is to experimentally observe exotic phenomena beyond the Standard Model (SM) that are predicted by theoretical models. These include hidden valley models, which predict the existence of a dark sector in which particles and...
Theoretical framework could improve data gathering in biological systems
To effectively adapt to change, living organisms rely on their ability to rapidly detect and process sensory information in their surroundings. The sensory information available at a given time continuously changes, which means that it can typically only be observed...
Study gathers strong evidence of the doubly magic nature of ¹⁰⁰Sn
Recent experiments at CERN have shed new light on the nuclear properties of atomic nuclei (i.e., the central regions of atoms accounting for most of their mass). A key objective of recent research into atomic nuclei has been to better understand the properties of...
Detecting Planck-scale dark matter by leveraging quantum interference
While various studies have hinted at the existence of dark matter, its nature, composition and underlying physics remain poorly understood.
