Physics News of the Week: Another Step Towards Detecting Gravitational Waves and What’s Going on at CERN
Another hot week of summer has passed and it’s time to overview what has been happening in the world of physics. So here’s a summary of the top news of this week. If you would like to receive these news straight to your email, please register for our email newsletter.
1. First Experimental Signs of Physics Beyond the Standard Model (July 31)
A team of physicists from the Universitat Autònoma de Barcelona (UAB) and the French CNRS have predicted certain deviations in the probability of one of the B meson decays, which were now detected in the LHC. These results, according to the scientists, given that they are confirmed, would be the first direct evidence of new physics beyond the standard model.
“We must be prudent, because more studies and more experimental measurements will be needed for confirmation,” explains Joaquim Matias, “but if they are confirmed this is the first direct proof of “New Physics”, a more general theory than the current Standard Model.” This “New Physics”, according to the scientists, might shed some light on the problems of dark matter and other great problems of physics.

Step after step scientists are moving towards the detection of gravitational waves
2. Another Step Towards Detecting Gravitational Waves (August 1)
In general theory of relativity, gravitational waves are like ripples in the curvature of space time. Predicted to exist by the Einstein’s theory of relativity, these waves are hunted by a network of gravitational wave observatories all around the globe. Now, another step has been made towards the ultimate discovery of these waves.
David Blair from The University of Western Australia has announced a discovery of a new technique of detecting gravitational waves. The new technique, called “quantum squeezing” will have a higher sensitivity than the current methods of detection. Read more here.
3. CERN Prepares for the Next Cosmic Quest (August 1)
After the great discovery of the Higgs boson, the scientists at CERN are working on an upgrade, which will enable a search for new physics. In particular, when experiments resume in 2015, scientists at the European Organisation for Nuclear Research (CERN) will use its enhanced power to probe dark matter, dark energy and supersymmetry.
In addition to preparations for the search of new physics, scientists are also re-analyzing the collected data to see if they missed anything interesting. “The things that are easy to spot have already been exploited, and now we’re taking another look,” said Tiziano Camporesi of CERN.
