Sung-Won Lee, an assistant professor of physics at Texas Tech and a member of the university’s High Energy Physics Group, said researchers have not given up finding any possible hints of new physics, which could add more subatomic particles to the Standard Model of particle physics.
Their findings were published recently in Physical Review Letters. Their results are the first of the “new physics” research papers produced from the CMS experiment at LHC.
“So far, we have not yet found any hint of the new particles with early LHC data, but we set the world’s most stringent limits on the existence of several theorized new types of particles,” said Lee, who co-led the analysis team searching for these new particles.
Currently, the Standard Model of physics only explains about 5 percent of the universe, Lee said.
“The Standard Model of particle physics has been enormously successful, but it leaves many important questions unanswered,” Lee said. “Also, it is widely acknowledged that, from the theoretical standpoint, the Standard Model must be part of a larger theory, known as ‘beyond the Standard Model,’ which is yet to be experimentally confirmed.”
Finding evidence of new particles could open the door to whole new realms of physics that researchers believe could be there, such as string theory, which posits that subatomic particles such as electrons and quarks are not zero-dimensional objects, but rather one-dimensional lines, or “strings.” It could also help prove space-time-matter theory, which requires the existence of several extra spatial dimensions to the universe as well as length, width, height and time.
One of the most popular suggestions for the ‘beyond the Standard Model’ theory is Supersymmetry, which introduces a new symmetry between fundamental particles, he said. Supersymmetry signals are of particular interest, as they provide a natural explanation for the “dark matter” known to pervade our universe and help us to understand the fundamental connection between particle physics and cosmology.
Furthermore there are a large number of important theoretical models that make strong cases for looking for new physics at the LHC.
“Basically, we’re looking for the door to new theories such as string theory, extra dimensions and black holes,” Lee said. “None of the rich new spectrum of particles predicted by these models has yet been found within the kinematic regime reachable at the present experiments. The LHC will increase this range dramatically after several years of running at the highest energy and luminosity.
“I believe that, with our extensive research experience, Texas Tech’s High Energy Physics Group can contribute to making such discoveries.”

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
