CMS observes new clues about early universe

This heavy-ion collision inside the CMS detector illustrates the jet-quenching phenomenon, an imbalance in energy between two jets that provides insight into the conditions of the universe at its birth.

This week the first heavy-ion run at CERN’s Large Hadron Collider concluded, giving the CMS experiment the perfect holiday gift: new clues about the conditions of matter in the very first moments of the universe.

The CMS collaboration, together with the ALICE and ATLAS experiments, presented their first heavy-ion results from this run in a seminar held at CERN last week on Dec. 2. CMS will publish a paper with its findings later this month.

When studying the early conditions of the universe, physicists rely on the basic building blocks of matter: quarks and gluons. The detector measures a jet of particles originating from these building blocks. In proton-proton collisions at the LHC jets come in pairs with approximately equal energy. In some fraction of heavy-ion collisions, however, the two jets are imbalanced, meaning one has more energy than the other. This energy difference occurs when one of the jets loses a significant amount of energy in the hot dense material created during the heavy-ion collisions of two beams of lead nuclei.

The process that causes this imbalance is called jet quenching. CMS directly observed this phenomenon for the first time during this heavy-ion physics run.

“We could see the imbalance very clearly when the run first began in early November,” said MIT physicist Bolek Wyslouch, who presented the CMS results at last week’s seminar.

CMS physicists expected to find jet quenching in the heavy-ion collisions, based on earlier observations from Brookhaven’s RHIC collider. CMS and ATLAS, working directly with jets and not single particles, observed this phenomenon for the first time. CMS scientists attribute their observation in part to the LHC's unprecedented energy and the CMS experiment's advanced measuring capability, which allowed them to build on the data from RHIC. 

Wyslouch credits mainly the CMS calorimeters for allowing them to make the direct observation. In CMS, the calorimeters completely cover the volume surrounding the collision. Past heavy-ion experiments only partially covered the collision.

“The CMS calorimeters allowed us to capture all of the energy from the jets,” Wyslouch said. “We benefited greatly from the experience of high-energy physicists studying jets in proton-proton collisions  on CMS.”

The CMS heavy-ion group has roughly 100 scientists from institutions around the world. The next heavy-ion run is scheduled for November 2011.

CMS has about 100 scientists in its heavy-ion group. Roughly half of them are at CERN now analyzing the new data.

Director's Corner


Fermilab Director Pier Oddone

Somebody could get rich translating our adventures at Fermilab into a fast-paced video game called LAB. We have all the elements: a cast of creative and colorful personalities, the possibility of great discoveries, a semi-infinite set of rules to live by, multiple institutions ranging from our national and international partners to the DOE, Office of Management and Budget and Congress all trying to help us. We have a set of diverse activities in our site comparable to those of a small city. And besides all these, we have a great sense of suspense that comes both from the surprises that science serves us and from the dragons that jump out at us from the most unexpected places. Getting to the brass ring before "game over" is quite a challenge. While this might make for an exciting video game, though, it probably does not make for optimal management of a scientific enterprise.

Last week one of those dragons jumped into our path. On Dec. 2 the National Science Board's Committee on Program and Plans voted not to recommend the proposed DUSEL bridge funding award. The award funds the DUSEL team that is creating the Preliminary Design Report and working in South Dakota maintaining safe access and carrying on operations in the existing facility. The bridge funding is necessary to keep the UC Berkeley and South Dakota teams at work until a formal decision on DUSEL by the National Science Board takes place. The present action by the CPP is very narrow and makes no statement about the merits of the science to be carried out at DUSEL. Nevertheless, it could have a devastating effect on the project if the issue of bridge funding is not resolved in a relatively short time.

In a message to the DUSEL team, Graham Fleming, the Vice Chancellor for Research at the UC Berkeley campus stated: “At this point, all of the major top‐level stakeholders are actively and personally engaged in finding ways to maintain the momentum that has been established.” Certainly on my trip earlier this week to D.C. to present Fermilab’s long-range plans to DOE I witnessed the strong efforts that some of these stakeholders are making to address the issue and participated in discussions to devise possible solutions. We hope their efforts will quickly resolve the huge uncertainty now plaguing our colleagues and partners in South Dakota and Berkeley—and our own scientific game plan.



Fermilab scientist Muzaffer Atac, ID 269 died Dec. 7. A memorial service will take place at 3:30 p.m. Saturday, Dec. 11, in the sanctuary of The Unitarian Universalist Society of Geneva, 110 S. 2nd St., Geneva, IL. A reception will follow. Fermilab Today will include additional information on Atac's life and work in a future issue.
