Angelo Di Canto wins 2013 URA Thesis Award

Angelo Di Canto

Angelo Di Canto has been fascinated by physics since he was young. He first came to Fermilab in 2006 as a summer undergraduate intern to begin learning how to do high-energy physics research.

Di Canto, now a postdoctoral scholar at the University of Heidelberg in Germany, won this year's URA Thesis Award for his work with charmed meson decay using CDF data taken at Fermilab.

Di Canto first started working on charmed meson decay as a Ph.D. student in 2009 at the University of Pisa. His thesis focused on searching for charge-parity violation in decays of charmed mesons. CP violation would show that charmed mesons and their antiparticles didn't behave the same way when their charge and orientation were reversed in space.

At that time, CDF data contained information on charmed mesons but it couldn't be extracted in an efficient fashion. Di Canto's thesis outlined a method to precisely measure and assess CP violation using tight controls on uncertainties and data collected from the Tevatron runs from 2002 to 2010.

"For the first time, we were able to measure these quantities to the precision that is actually needed to start probing many aspects of the Standard Model and seeing if new physics might appear," Di Canto said.

Di Canto's thesis was one of 17 nominees for the award.

"Measurements of the asymmetry using decay into pions and particularly kaons had never been made with comparable precision and control of systematics," said Robert Zwaska, URA thesis committee chair. "Angelo had to do a lot of that work by himself, which speaks to the amount of intellectual involvement he had in it."

CP violation in particles is important because it helps scientists understand the behavior of matter and antimatter and how it fits into the bigger picture of the universe, Zwaska said.

Charmed mesons, Zwaska said, are an "untapped area." Because charmed mesons are almost always found in regimes with many other particles with similar masses and properties, extracting that data can be difficult.

Zwaska also said that the quality of Di Canto's thesis in terms of writing and clarity stood out among the others.

"The award came as a surprise for me, but I was excited and happy to receive it," Di Canto said.

The judges focused on clarity, originality and physics content in their decisions, Zwaska said.

"The URA Thesis Award conferred on Angelo Di Canto recognizes both his outstanding work and the vital role that Fermilab plays in the education and training of young scientists," said Marta Cehelsky, executive director of URA.

International Linear Collider design is 'good to go'

Yesterday, at a series of events held on three continents, scientists celebrated the completion of the design for a next-generation particle collider, the International Linear Collider.

At these events, the ILC Global Design Effort collaboration officially submitted its design of the proposed International Linear Collider to the International Committee for Future Accelerators, the oversight board for projects in particle physics. The completion of the Technical Design Report, a detailed blueprint of the ILC, fulfills the GDE's mandate to design a collider that would complement and advance the physics of the Large Hadron Collider at CERN.

It was a day the ILC community had been working toward since the GDE was formed in 2005—and thus a day for celebration. True to its commitment to internationality, the ILC collaboration commemorated the achievement with a worldwide party.

On June 12, starting in Tokyo, continuing at CERN and ending at Fermilab, scientists and their guests recognized the success with symposia, public events, receptions and a series of ceremonial handovers of the completed report. The three regions gave each other a virtual handshake by videoconference when one celebration ended in one time zone and the next started in another.

"The Technical Design Report is an impressive piece of work that shows maturity, scrutiny and boldness," says Lyn Evans, Director of the Linear Collider Collaboration, which oversees the ILC project. "The International Linear Collider should be next on the agenda for global particle physics."

Scientists unveil plans for 19-mile-long particle smasher

From CNET, June 12, 2013

The Large Hadron Collider is a monumentally awesome machine, and has given us tentative confirmation of the existence of the Higgs boson, the so-called "God particle." Now scientists hope to follow that with a new accelerator that could explain what makes up 95 percent of the universe.

At three ceremonies around the world Wednesday, researchers hailed blueprints for the International Linear Collider (ILC), a 19-mile-long smasher that might help solve the riddle of dark matter and dark energy, unseen forces with major gravitational effects.

Frontier Science Result: CMS

Looking in many boxes

Searching for particles smaller than any previously discovered requires looking into lots of different boxes. An earlier search using leptons was unsuccessful, so this analysis turned to quarks.

In February, I wrote an article that described a search for the smallest building blocks of matter. Currently, the best description we have of the subatomic realm is the Standard Model, and this theory treats particles called quarks and leptons as having no size at all. On the other hand, the history of physics is full of particles that were once thought to be the smallest of the small and turned out not to be: Atoms, atomic nuclei and protons are the best known ones.

If there are particles smaller than the ones we know, then there is some sort of force that binds the smaller particles into the familiar quarks and leptons. When we begin to probe the smaller scale, we expect to encounter new physics, and the character of the data will change. Because these changes will be caused by contacting the new physical phenomena, these kinds of pursuits are called "contact interactions," and the math treats the interactions as if the particles actually come into contact.

In the earlier article, I described how CMS scientists were searching for contact interactions in the production of leptons. This allows physicists to see if there is new physics to be found at the smallest scales when investigating electrons and muons.

There is no guarantee that leptons are the right place to search for new phenomena. Leptons may be sufficiently point-like that we can't see contact interactions using our equipment. However, it is possible that quarks and gluons are less point-like than leptons. Accordingly, it is important also to check the data for contact interactions for quarks. CMS has looked for any evidence of new physics occurring at very small scales when quarks are scattered. No evidence for unexpected contact interactions was discovered.

—Don Lincoln

These US CMS scientists contributed to this analysis.
The 2013 annual US CMS meeting took place recently at Vanderbilt University. For any such event to run smoothly, postdocs, graduate students and undergraduates are enlisted to help with operations, including running projection systems, making copies and helping visitors solve all manner of unexpected problems. These Vanderbilt University physicists were instrumental in making the meeting a spectacular success.
In Brief

Weather delays move of Muon g-2 ring by one week

The move of the Muon g-2 ring from Brookhaven Laboratory to Fermilab begins Saturday, June 22.

Because of inclement weather on the east coast, the move of the 50-foot-wide Muon g-2 electromagnet has been delayed by one week. The current plan would see the ring move across the Brookhaven National Laboratory site on Saturday, June 22, and down the William Floyd Parkway to the Smith Point Marina the night of Sunday, June 23, and into the morning of Monday, June 24.

Project leaders are concerned about the safety of workers who could be caught in heavy storms predicted for today in New York. The team has a few days of prep work to finish loading the electromagnet onto the truck, work that will be delayed by the wind and rain. The storms are not expected to damage the magnet.

Once the magnet is secured to the barge, it will begin its four-to-six-week journey to Illinois, rounding the tip of Florida and taking a series of rivers north. When it arrives, the ring will be loaded onto the truck again and driven to Fermilab over three consecutive nights. It will eventually be housed in a new building under construction near Wilson Hall.
