Particle physics experiment at LHC zeroes in on magnetic monopoles

 




The MoEDAL (Monopole and Exotics Detector) experiment at the Large Hadron Collider (LHC), which is the world’s largest and highest-energy particle collider, has made a significant leap in its quest for magnetic monopoles. Reported in two papers posted on the arXiv preprint server, the collaboration has narrowed the search window for these magnetic charge-bearing particles. The latest searches conducted by the MoEDAL experiment shrink the theoretical arenas in which the hunt for magnetic monopoles can continue, according to the European Council for Nuclear Research (CERN).


No magnetic monopoles or high-electric-charge objects 

The MoEDAL team found no magnetic monopoles or high-electric-charge objects (HECOs) in their latest scanning of the trapping volumes. But it set bounds on the mass and production rate of these particles for different values of particle spin, an intrinsic form of angular momentum. “MoEDAL’s search reach for both monopoles and HECOs allows the collaboration to survey a huge swathe of the theoretical ‘discovery space’ for these hypothetical particles,” said MoEDAL spokesperson James Pinfold. According to CERN, the MoEDAL team in its second latest study concentrated on the search for monopoles produced via the Schwinger mechanism in heavy-ion collision data taken during Run 1 of the LHC.

Scanned beam pipe in search of trapped monopoles

The team scanned a decommissioned section of the CMS experiment beam pipe, instead of the MoEDAL detector’s trapping volumes, in search of trapped monopoles. Once again, the team found no monopoles, but it set the strongest-to-date mass limits on Schwinger monopoles with a charge between 2gD and 45gD, ruling out the existence of monopoles with masses of up to 80 GeV, as per CERN. “The vital importance of the Schwinger mechanism is that the production of composite monopoles is not suppressed compared to that of elementary ones, as is the case with the Drell–Yan and photon-fusion processes,” explains Pinfold. “Thus, if monopoles are composite particles, this and our previous Schwinger-monopole search may have been the first-ever chances to observe them.”

"Explore the Fourth Dimension"

Fourth Dimension   The fourth dimension is a fascinating concept that has captured the imaginations of scientists, mathematicians, and artists for centuries. Unlike our three-dimensional world, which is limited by the linear flow of time, the fourth dimension is a realm of space and time that exists beyond our everyday experience. One way to visualize the fourth dimension is through the use of a hypercube, also known as a tesseract. A hypercube is a cube within a cube, with additional lines and edges connecting the vertices of the two cubes. It's impossible to construct in our three-dimensional world, but it provides a glimpse into what the fourth dimension might look like. Another way to understand the fourth dimension is through the concept of a wormhole, a theoretical passage through space-time that connects two distant points in the universe. A wormhole is like a shortcut through the fabric of space-time, allowing us to travel vast distances in an instant. While there is no de...

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Quantum Tunneling Breakthrough: Technion Scientists Move Atoms With Precision

In a groundbreaking experiment at the Technion Faculty of Physics , researchers demonstrated the transfer of atoms via quantum tunneling using optical tweezers. This novel method, which strategically avoids trapping atoms in the middle tweezer, represents a notable stride toward innovative quantum technologies. Quantum Tunneling in Optical Tweezers A new experiment at the Technion Faculty of Physics demonstrates how atoms can be transferred between locations using quantum tunneling with optical tweezers. Led by Prof. Yoav Sagi and doctoral student Yanay Florshaim from the Solid State Institute, this research was published recently in Science Advances. The experiment relies on optical tweezers , a powerful tool that uses focused laser beams to trap and manipulate tiny particles like atoms, molecules, and even living cells. Here’s how it works: when light interacts with matter, it creates a force proportional to the light’s intensity. This force, though too weak to impact larger objects,...
