Los datos muestran que se formó un plasma de quarks y gluones y que las partículas de alta energía perdieron energía al atravesarlo.","fuente":"phys","fuenteNombre":"Phys.org","color":"#2b5c8a","autor":"","url":"https://phys.org/news/2026-10-oxygen-collisions-evidence-jet-quenching.html","imagen":"https://scx1.b-cdn.net/csz/news/tmb/2026/illustration-shows-bac.jpg","tema":"ciencia","subtemas":["física de partículas","plasma de quarks y gluones","big bang","aceleradores de partículas","colisiones nucleares"],"entidades":["STAR","RHIC","Brookhaven National Laboratory","Physical Review Letters"],"formato":"dato","entretenimiento":false,"pubTs":"2026-10-20T21:20:01.000Z","indexTs":"2026-10-20T21:22:18.098Z","hash":"a2b6fa1d0cede8e1cf38ac81cf633295edcaf083a46ddc217e5543214f6aeb34","tsa":{"time":"Oct 20 21:22:47 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"normal","registro":"hallazgo","porQueImporta":"Lo que se logró es generar, en un laboratorio, un tipo de materia que existió apenas después del Big Bang, y eso permite estudiarla de forma directa. Para la ciencia argentina y latinoamericana esto abre una vía de investigación accesible con datos ya publicados. Para el resto de nosotros, es una muestra de cómo los experimentos más extremos sirven para entender de qué está hecho el universo. Aunque el resultado es sólido, todavía hay que confirmarlo con más experimentos y otras condiciones de colisión.","quienFirma":"Brookhaven National Laboratory (experimento STAR)","confianza":"revisado","consulta":null},"sello":{"hash":"a2b6fa1d0cede8e1cf38ac81cf633295edcaf083a46ddc217e5543214f6aeb34","sello":"7e02bcc65484b0febe1d9df8b972f1006f9ef70c60e205f20f6beda14c333ace","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6570011,"aleatorio":"f4df98697a4d885f389bda59abebc2646a0589095f07e47dd19ef65f4fcc9cfc","tiempo":"2026-10-20T21:22:30.000Z"},"nist":{"cadena":2,"pulso":1992211,"salida":"297820F4ACCBFEA0C8521236B72869BF86525480B5EEDD5A132F0DE023A235CD0F1ED841341CB983C22891DFABD398F8DC2988003433402C708D71FF0AFDC616","tiempo":"2026-10-20T21:22:00.000Z"},"noAntes":"2026-10-20T21:22:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 20 21:22:47 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Oxygen collisions show evidence of jet quenching, a signature of early-universe matter","descripcion":"New results from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) provide strong evidence that smashing oxygen nuclei together at nearly the speed of light generates a quark-gluon plasma (QGP), a type of matter that existed just after the birth of the universe.
