Neutrino interaction rates measured at unprecedented energies
A team including researchers from the Laboratory for High Energy Physics at the University of Bern has successfully measured the interaction rates of neutrinos at unprecedented energies using the Large Hadron Collider (LHC) at CERN. The study was published in the journal Physical Review Letters.
Physicists pool skills to better describe the unstable sigma meson particle
While nuclear physicists know the strong interaction is what holds together the particles at the heart of matter, we still have a lot to learn about this fundamental force. Results published earlier this year in Physical Review D by three researchers in the Center for Theoretical and Computational Physics at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility bring us closer to understanding an important piece of the strong interaction puzzle.
Strange Motion of Neutrons Proves Nature Is Fundamentally Bizarre
At the very smallest scales, our intuitive view of reality no longer applies. It’s almost as if physics is fundamentally indecisive, a truth that gets harder to ignore as we zoom in on the particles that pixelate our Univerrse.
In order to better understand it, physicists had to devise an entirely new framework to place it in, one based on probability over certainty. This is quantum theory, and it describes all sorts of phenomena, from entanglement to superposition.
Yet in spite of a century of experiments showing just how useful quantum theory is at explaining what we see, it’s hard to shake our ‘classical’ view of the Universe’s building blocks as reliable fixtures in time and space. Even Einstein was forced to ask his fellow physicist, “Do you really believe the Moon is not there when you are not looking at it?”
New LHC results refute Fermilab’s “hole” in the Standard Model
With new W-boson, top quark, and Higgs boson measurements, the LHC contradicts earlier Fermilab results. The Standard Model still holds.
How faster-than-light ‘tachyons’ fit into the special theory of relativity
In the world of physics, the idea of particles moving faster than light has always been a bit of a wild card. These particles, known as tachyons, have stirred up debates and skepticism.
However, a recent study published in Physical Review D has shaken up our understanding of these enigmatic particles.
For a long time, tachyons were considered more of a theoretical oddity than a scientific possibility. They seemed to conflict with the special theory of relativity, which has been a cornerstone of modern physics.
How a Twist in Physics Could Change Technology Forever
Physicists at the University of Konstanz have discovered a way to imprint a previously unseen geometrical form of chirality onto electrons using laser light, creating chiral coils of mass and charge.
This breakthrough in manipulating electron chirality has vast implications for quantum optics, particle physics, and electron microscopy, paving the way for new scientific explorations and technological innovations.

Oxygen tweaking may be key to accelerator optimization
Particle accelerators are pricey, but their cost comes with good reason: These one-of-a-kind, state-of-the-art machines are intricately designed and constructed to help us solve mysteries about what makes up our universe. Still, the scientists and engineers building these machines must do their best to save where they can. Researchers at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility are supporting this mission by figuring out how to optimize cavities, one of the most critical parts of an accelerator.
