Physicists pool skills to better describe the unstable sigma meson particle
Posted by Saúl Morales Rodriguéz in categories: computing, particle physics
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
Posted by Shubham Ghosh Roy in categories: particle physics, quantum physics, space
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
Posted by Shubham Ghosh Roy in category: particle physics
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
Posted by Shubham Ghosh Roy in category: particle physics
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
Posted by Genevieve Klien in categories: particle physics, quantum physics
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
Posted by Saúl Morales Rodriguéz in category: particle physics
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.

Quantum Revelations: Unveiling New Layers of the Higgs Boson
Posted by Saúl Morales Rodriguéz in categories: particle physics, quantum physics
New research confirms the Standard Model’s predictions about the Higgs boson while suggesting future data may reveal unknown aspects of particle physics.
The Higgs boson was discovered in the detectors of the Large Hadron Collider a dozen or so years ago. It has proved to be a particle so difficult to produce and observe that, despite the passage of time, its properties are still not known with satisfactory accuracy. Now we know a little more about its origin, thanks to the just-published achievement of an international group of theoretical physicists with the participation of the Institute of Nuclear Physics of the Polish Academy of Sciences.
