Would you bet on a Pentaquark?

19.02.2008
In 2003 the discovery of a new type of particle, a Pentaquark, was heralded with a great fanfare.

Within two years, however, follow-up experiments had failed to find it. Belief in the existence of a pentaquark has since dwindled, but what was the reason for the apparent contradictory results? Physicists at the University of Glasgow think they have now resolved the problem.

The conventional measure for the discovery of a new particle is that there is a less than 1 in a million chance that the result was a fluke. However, even at the height of the pentaquark excitement, fewer than half the researchers in the field really believed that a new particle had been found.

By considering the odds at which someone would make a bet on the pentaquark's existence, and applying the theory of chance developed by the Rev. Thomas Bayes in the 19th century, the Glasgow team found that the original result was far less conclusive than had been thought, and was in fact compatible with the new results.

Dr David Ireland, Physics and Astronomy, University of Glasgow, said: “If the authors had been licensed betting operators, they would now have been prepared to take bets at odds of 10 to 1 against there being a pentaquark!

“The mathematics at the heart of this work is actually also embedded into the techniques used by Google for efficient searching of the internet, as well as several other artificial intelligence systems. And the proposed technique can be applied to any experiment aimed at discovering new particles.”

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
