China Net/China Development Portal News Recently, China NZ EscortsResearchers from the Institute of Modern Physics of the Academy of Sciences and other institutions participated in the RHIC-STAR international cooperative experimental research and observed for the first time in the relativistic heavy ion gold-gold collisionNZ EscortsA new antimatter supernucleus – antihyperhydrogen-4, which is the heaviest antimatter supernucleus experimentally discovered so far. The relevant results were published in the journal Nature on August 21.
Heavy ion collisions produce antimatter superhydrogen-4
Current physics knowledge believes that matter and antiZelanian EscortThe nature of matter is symmetrical. Newzealand SugarAt the beginning of the universe, there should be equal amounts of positive matter and AntimatterSugar Daddyquality. Fortunately, some mysterious physical Sugar Daddy mechanism resulted in a very small asymmetry in the amount of matter and antimatter in the early universe. After the annihilation of matter and antimatter, about one tenth of a billionth of matter survived, forming today’s material world and becoming the basis for the birth and existence of human civilization. What causes the difference in the amount of matter and antimatter in the universe? To answer this open question, an important ideaNewzealand Sugar is to create new antimatter in the laboratory and study their properties.
Antimatter is very rare, and from a few “The bride is really Master Lan’s daughter.” Pei Yi said. Anti-baryons are further combined to form antimatter nuclei and antimatter supernuclei (i.e. packages) “Who told you? Your grandmother?” she asked with a wry smile, and another blood heat surged from her throat Zelanian Escort, let her swallow it before spitting it out. Atomic nuclei containing hyperons such as Lambda) are even more difficult to produce. Since the Dirac equation in 1928Newzealand Sugar“Newzealand Sugar Since “Negative Energy Solution” predicted the existence of antimatter, scientists have discovered only 6 types of antimatter (super) nuclei in the past century.
The anti-superhydrogen-4Zelanian Escort discovered this time was produced in a relativistic heavy ion collision experiment. Relativistic separation at Brookhaven National Laboratory, USANewzealand SugarThe state of the early Zelanian Escort Big Bang. This collision can produce Zelanian sugar a high-temperature fireball of several trillion degrees, containing almost Zelanian sugarEqual amounts of positiveNZ Escortsmatter and antimatter. The fireball expands and cools rapidly, giving some antimatter a chance to escape and annihilate NZ EscortsmatterZelanian sugar‘s fate was observed by the STAR experimental detector orbiting the collision site.
Antihyperhydrogen-4 is composed of an antiproton, two antineutrons and an antiLambda hyperon. Because it contains unstable anti-Lambda hyperons, anti-H-4 decays after just a few centimeters of flight. The research team analyzed Sugar Daddy experimental data from a total of about 6.6 billion heavy ion collision events. Antihelium-4 and antihelium-4 produced through decay π+ meson NZ Escorts reversely reconstructed anti-superhydrogen-4, and finally obtained about 16 anti-superhydrogen-4 signals.
Research TeamNZ Escorts also Zelanian Escortmeasured the lifetime of anti-superhydrogen-4 and compared it with its corresponding positive particle superhydrogen-4. The measurement accuracyZelanian suThere is no obvious difference in the lifespan between the two within the gar range. Sugar Daddy once again verified the symmetry of the properties of matter and antimatter.
Anti-superhydrogen-4 is the heaviest antimatter supernucleus currently observed by scientists. , asked her where she was at her husband’s house. of everything. Its discovery and study of its properties have taken another important step forward in the exploration of antimatter and the symmetry of matter and antimatter.
SNewzealand SugarTAR is a large-scale international experimental cooperation group on RHIC, consisting of 74 members from 14 countries. The unit consists of more than 700 researchers. The work was funded by the Chinese Academy of Sciences NZ Escorts “If I say no, it won’t work.” Pei’s mother was not willing to compromise at all. Zelanian Escort led the team of researcher Qiu Hao from the Institute of Contemporary Physics. Ph.D. students Wu Junlin and Lu Tan made outstanding contributions in the physical analysis. .
