Wits physicists help Collider quest for new particle

Published

on

Local scientists are exploring the possible discovery of a new particle with the help of the Large Hadron Collider at CERN in Switzerland.

New results from the Large Hadron Collider at the European Organization of Nuclear Research (CERN) have scientists exploring the possibilities of yet another new particle.

The tantalizing hints of a new particle beyond the known Standard Model of Particle Physics were reported independently by the ATLAS and CMS experiments and announced on Tuesday, 15 December 2015.

Wits University researchers are deeply involved at CERN and also contributed to the discovery of the Higgs boson three years ago.

The discovery of the Higgs boson, an elusive particle that is responsible for the generation of mass of known elementary particles, was announced on 4 July 2012 – almost five decades after it was postulated.

“With the discovery of the Higgs boson a new window of opportunity has opened to discover new particles and interactions in nature. These may help us understand many unresolved mysteries, such as where most of the matter in the Universe comes from, among others,” says Professor Bruce Mellado from the Wits School of Physics.

Now, following a two-year shutdown for re-commissioning, the Large Hadron Collider restarted earlier this year.  It also provides an insight of what happened right after the Big Bang via the study of collisions of heavy ions at high energies.

In June 2015 it has resumed in providing proton-proton collisions for physics data at a record energy of 13 TeV (1012 eV). The Higgs boson was discovered with data collected at 7 TeV and 8 TeV.

Then on 25 November 2015, the first heavy ion collisions at a record energy of more than 1 PeV (1015 eV) were provided.

The results following the data analysis by the ATLAS and CMS experiments bears witness of the excellent readiness of the experiments to collect, distribute and analyze vast amounts of data in a short period of time.

“Getting these exciting results from LHC Run two depended on understanding the early measurements at this new center-of-mass energy, where the Wits group played a significant role,” says Dr Deepak Kar of the Wits School of Physics.

“The amount of data delivered in 2015 is a glimpse of what will be delivered next year. New data is expected to be delivered starting at the end of April 2016, leading to a data sample significantly bigger than obtained in 2015. This data set will give an invaluable insight on whether we will have new discoveries or not,” says Mellado.

CES: So long, and thanks for all the beer!

Last week, the Las Vegas expo showed off its fun side with state-of-the-art technologies for enjoying beer, writes BRYAN TURNER

From craft beer-making machines to robots that pour beer, CES had more beer than usual in Las Vegas last week. And even free beer if you found the right stand. Stampede’s saloon-style booth offered beer to visitors who tried out its latest drones, virtual reality, and other gaming products. No beer tech, though.

Here are some of the beer technologies that stood out:

LG HomeBrew – Craft beer made at home

LG’s HomeBrew craft beer-making machine,  debuted at CES 2019, brings the brewing process home thanks to single-use capsules,  a self-cleaning feature, and an algorithm optimised for fermentation. 

Like a Nespresso coffee machine, the beer maker uses capsules, which contain malt, yeast, hop oil and flavouring. At the press of a button, LG HomeBrew automates the whole procedure from fermentation and carbonation to ageing. A companion app lets users check HomeBrew’s status at any time during the process, from their handsets.

The beer machine not only offers a simple way to make craft beer, but also enhances the quality of beer it makes. The fermentation algorithm intelligently controls the fermenting process with precise temperature and pressure control. It automatically sanitises itself, using nothing more than hot water, ensuring everything is hygienically clean for the next batch.

Designed with discerning beer lovers in mind, HomeBrew allows for in-home production of batches of more than 4 litres of beer in a variety of styles. The following five distinctive, flavoured beers are available now: 

  • Hoppy American IPA
  • Golden American Pale Ale
  • Full-bodied English Stout
  • Zesty Belgian-style Witbier
  • Dry Czech Pilsner

The only catch? It takes about two weeks to make, depending on the beer type.

“LG HomeBrew is the culmination of years of home appliance and water purification technologies that we’ve developed over the decades,” said Dan Song, president of LG Electronics Home Appliance & Air Solutions Company. “Homebrewing has grown at an explosive pace, but there are still many beer lovers who haven’t taken the jump because of the barriers to entry, like complexity, and these are the consumers we think will be attracted to LG HomeBrew.”

CES: Alienware gets Legend-ary

Published

on

At CES in Las Vegas last week, Dell’s Alienware released a family of high-end, thin, light, and affordable machines for both amateur and professional gamers – and a new identity.

Alienware marked CES 2019 as a brand milestone with the debut of a new design identity, Alienware Legend. It aims to set a new bar of excellence for what gamers want most – performance and function. Alienware says it evaluated multiple concepts and chose one that was the biggest and boldest departure from its current look.

Alienware Legend, says the company, stays true to the brand’s core design tenets, taking cues from its deep roots in sci-fi culture and its early industrial designs, to distinguish the brand from the rest of the industry. The new Legend design is optimised with cutting-edge thermal cooling technology to achieve and sustain overclocking power, improved AlienFX lighting, and ultra-thin screen borders. It also unveiled a new “three-knuckle hinge” design that reduces the overall dimension while creating a stronger assembly, all combining to yield a better gaming experience.

“We’re excited to come to this year’s CES with some truly groundbreaking products, next-gen software and strategic partnerships that will bring more people to experience PC gaming and advance the industry,” said Frank Azor, vice president and general manager of Alienware. “The legend design answers the call for more and better from our gaming community, and the new G Series laptops will make PC gaming even more accessible to those looking for high-performance gaming at a cost they can appreciate.”
