When matter and anti-matter particles collide at high energies, clean energy is released, which produce new particles and anti-particles. Oversee day-to Fermilabi scientists for hundreds of millions of such collisions. Similar events took place in the early days of the universe would have had to produce a substance, and the substance was given exactly the same amount. At the moment, we know the universe is composed of only ordinary dp stream matter, dp stream however, and there will be only a short-lived antimatter particles põrgutites, from nuclear or cosmic rays due. This symmetry breaking is due to become a question dp stream "What happened to the anti agent?" One of the 21st century, the central problems in particle physics.
Last Friday, May 14, DZero experiment announced Tevatroni accelerator collectively, they have found evidence of matter, antimatter symmetry in serious breach. Deviation discovered in researching Bottom, also known under the name of Beauty, subatomic particles containing quarks. In recent behavior does not seem to fit the current standard model of particle physics. International, dp stream with more than 500 physicists working group composed of the results showed that the B-meson formed out müüonite and antimüüonite dp stream There were one percent difference.
DZero result is based on the high energies of proton-Antiproton collisions taking place in emerging positively and negatively dp stream charged müüonite investigation division: DZero particle detector in a strong magnetic field causes a collision occurring müüoneid move in different directions. Two opposite charge müüonit move exactly in opposite directions. First, the researchers had to compare the distribution of müüonite when the magnetic field was oriented in one direction (first configuration). Müüonite Subsequently they studied the distribution of the magnetic field oriented in the opposite case (the second configuration). Antiaiane perfect symmetry of matter and the case should have two configurations to provide exactly the same result. Instead, however, found the DZero experiment, the scientists working in the distribution of matter and antiaiane 1% difference. Photo: Fermilab.
New methods of analysis and DZero detector accuracy through Working Group showed that the probability dp stream that the measurements dp stream are made in accordance with the presently known physical phenomena is less than 0.1 % (3.2 standard deviations). "These new results show that decomposition occurs dp stream at the B-meson theory anomalies, which is consistent with previous surveys, "said Dmitri Denisov, DZero experiment spokesperson. Observed last year Tevatroni both experiments, CDF and DZero, physicists working at such events and Bottom-Strange-quark particles composed.
The mere fact that the modern universe consists of only ordinary matter, automatically dp stream means that particles and anti-particles behave differently in the same circumstances. Although dp stream this difference in the behavior of the particle physicists have been observed for decades (CP-violation), they were still too small to explain why the universe is still anti-matter, or does not consist of pure energy. Also, these differences have been in full accordance with the standard model. If Fermilabi physicists observations further confirmed by the analysis, it can mean the next step in the phenomenon itself, which causes the ordinary matter dp stream than antimatter domination, detection.
The new results, data were analyzed by DZero physicists "blind," that prevent prejudiced interpretation of observational data. Only after a lengthy analysis methods, verification of the accuracy of the data collected, they looked at the whole set. Also, they changed the polarity of the magnetic field of the detector at the time of data collection in order to avoid anomalies that may arise in instrumentation.
DZero results are based on data collected over the past eight years, more than 6 pöördfemtobaari the size of the total brightness, equivalent to a thousand trillion protons for Antiproton and clashes. "Many of us rose goose bumps when we saw the final results. We knew that we see something that we have never seen before, and not by the current theories are unable to explain, "described the discovery Stefan Solder-Rembold, co-spokesperson for the DZero.
However, there is still limited to the accuracy of the data collected during the experiment, the number of collisions that have been carried out so far. It
