Searching for the decay of nature’s rarest isotope: Tantalum-180m

Searching for the decay of nature’s rarest isotope: Tantalum-180m

Particle physicsPhysics

By César Tomé

Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope. In excited states, a nuclei’s protons or neutrons have higher than normal energy levels. Although energetically possible, the radioactive decay of this excited […]

A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe’s most powerful magnetic fields on “deconfined” nuclear matter . The evidence comes from […]

By César Tomé

Collisions of high energy particles produce “jets” – quarks, antiquarks, or gluons moving through the quantum vacuum. Due to the confinement property of strong interactions, quarks are never directly detected but instead fragment into many secondary particles. Scientists have long expected that as jets propagate through the confining quantum vacuum, they will modify that vacuum […]

Deep below the Spanish side of the Pyrenees, we find the LSC (Laboratorio Subterráneo de Canfranc – Canfranc Underground Laboratory), where the NEXT experiment is taking place. Its goal is one of the remaining holy grails of particle physics: the proof that the neutrino is its own antiparticle, a result with profound meaning not only […]

spallation Progress in particle physics has traditionally been achieved by a symbiosis of experiments at the energy and intensity frontiers and model-building. This has led to the current situation of the Standard Model (SM) representing our best knowledge of particle physics, but which leaves a number of open questions to be resolved. These include the […]

By César Tomé

Scientists working on the Dark SRF experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have demonstrated unprecedented sensitivity in an experimental setup used to search for theorized particles called dark photons. Researchers trapped ordinary, massless photons in devices called superconducting radio frequency cavities to look for the transition of those photons into […]

The observation of the neutrinoless double beta decay is the only practical way to establish that neutrinos are their own antiparticles. But, because of the small masses of neutrinos, the lifetime of neutrinoless double beta decay is expected to be at least ten orders of magnitude greater than the typical lifetimes of natural radioactive chains […]

Concluding that the neutrino is a Majorana particle would be really a turning point in our understanding of the universe. It would mean the non-conservation of a magnitude called the leptonic number, one of the key characteristics in a fermion, meaning that there would be an explanation to the matter-anti matter asymmetry: the creation of […]
