Researchers say it will help determine which theory on the laws of the universe is most plausible.

The study, conducted by researchers at Brazil’s São Paulo University (USP) and the University of Campinas, determined that there is a symmetry between the nuclei of particles and their antiparticles in terms of charge, parity, and time. The research was published in the journal Nature Physics.

The experiment was part of an investigation to detect differences between the ways in which protons and neutrons join in nuclei while their antiparticles form antinuclei.

“After the Big Bang, for every particle of matter an antiparticle was created. In particle physics, a very important question is whether all the laws of physics display a specific kind of symmetry known as CPT, and these measurements suggest that there is indeed a fundamental symmetry between nuclei and antinuclei,” said Marcelo Gameiro Munhoz, a professor at USP’s Physics Institute (IF), as quoted by Phys.org.

The measurements were made possible by ALICE (A Large Ion Collider Experiment), a heavy-ion detector on the Large Hadron Collider (LHC) ring. It measured particles produced in high-energy collisions of heavy ions in the LHC. This process allows for the study of matter at extremely high temperatures and densities.

The collisions were found to produce a large number of particles and antiparticles, producing nuclei and antinuclei at nearly the same rate. Using this data, ALICE was able to make a detailed comparison of the properties of nuclei and antinuclei that were most abundantly produced.

After measuring both the curvature of particle tracks in the detector’s magnetic field and the particles’ time of flight, that information was then used to determine the mass-to-charge ratios for nuclei and antinuclei.

Munhoz believes the finding can help physicists determine which of the theories on the fundamental laws of the universe is most plausible.

“These laws describe the nature of all matter interactions,” he said, “so it’s important to know that physical interactions aren’t changed by particle charge reversal, parity transformation, reflections of spatial coordinates and time inversion. The key question is whether the laws of physics remain the same under such conditions.”

The existence and relationship between matter and anti-matter has long stumped scientists who believe, based on existing theories, that the Big Bang should have produced equal amounts of both, which would have resulted in the two immediately destroying each other.

]]> CERN’s membership: Pakistan hopes to be part of prestigious science research club https://muslim-science.com/cerns-membership-pakistan-hopes-to-be-part-of-prestigious-science-research-club/ https://muslim-science.com/cerns-membership-pakistan-hopes-to-be-part-of-prestigious-science-research-club/#respond Tue, 18 Feb 2014 06:09:02 +0000 http://muslim-science.com/?p=1289 By Peer Muhammad

Pakistan is aspiring to become an associate member of European Organisation for Nuclear Research (CERN). The application from Pakistan for the associate membership was submitted one year back, in February 2013.

A four-member high powered CERN Technical Team (CTT) – led by CERN’s Director for Research and Scientific Computing, Dr Sergio Bertolucci – is due to arrive on Monday (today) on a four-day visit to Pakistan, as part of the evaluation process for the Associate Membership (AM) of CERN for Pakistan.

Besides holding meetings with the authorities concerned, the team will also hold meetings with Prime Minister Nawaz Sharif and President Mamnoon Hussain to discuss the relevant issues, said Pakistan Atomic Energy Commission (PAEC) Director PR Shahid Riaz. He said the CTT would assess and evaluate the scientific activities being undertaken in Pakistan. “The Team will also visit universities, scientific organisations and industrial complexes in the country,” he added.

Riaz said CERN, located in Geneva, Switzerland, gave preference to Pakistan because of the contribution of Pakistan to CERN in terms of manpower as more than 30 Pakistani scientists always work in the research organizations.

“Pakistan has a very cordial relationship with CERN, which is the world’s leading scientific organization conducting research on High Energy Particle Physics since its inception in 1954,” he said.

CERN members include 20 European countries. Recently, Israel has been accorded imembership. CERN has three associate members and five observer states including India.

“There are numerous benefits, if Pakistan becomes CERN’s associate member. These include engineering contracts to support CERN programmes, which will be beneficial for our industrial sector and human resource development,” he said, adding that it would also help in technology transfer in key areas of radiofrequency (RF) technology, ion beam optics, cryogenics.

More recently, it has been concluded, that Pakistan has qualified to meet the criteria in order to become a member of CERN. Bertolucci lauded Pakistani engineers and scientists and said that “Pakistan has a first class pool of scientists and engineers, a requirement to become an associate member of CERN.”

He added that Pakistan and CERN are working in close collaboration from quite some time and the work from Pakistan’s industries is favourable.
