Joe Incandela elected CMS spokesperson

Joe Incandela

Members of the CMS collaboration have elected as their new spokesperson Joe Incandela, a physicist at the University of California, Santa Barbara. He is the first scientist from a U.S. institution to be elected spokesperson of an experiment at the LHC.

Incandela’s primary aim as spokesperson will be to help CMS collaboration board chair members create a sustainable mode of working together that allows them to fulfill all of their future goals, he said.

“I want us to have the feeling of a team or a family,” Incandela said. “We’re going to spend the next 20 or 30 years together.”

Incandela, a former member of Fermilab’s CDF experiment, will start his two-year term on Jan. 1, 2012.

“It’s going to be an exciting time,” said US CMS physicist Nick Hadley, who served on the election committee. “We’ll be taking data and publishing. Then the spokesperson will need to carefully choreograph the upgrade, since the CMS detector can only be opened in a particular sequence.”

Incandela will lead scientists from almost 40 countries in his new role.

Incandela has served as CMS deputy spokesperson since January 2010, when current spokesperson Guido Tonelli appointed him to the job along with CERN physicist Albert De Roeck.

Incandela earned his Ph.D. from the University of Chicago. He went to Switzerland as a CERN Fellow in 1987 to study W and Z bosons and then on to INFN in Italy to search for charged Higgs bosons. In 1991 he came to Fermilab as a Wilson Fellow and joined the CDF collaboration, where he co-led the experiment’s successful first observation of top quarks with secondary vertex b-tagging. He remained part of the CDF collaboration for 18 years.

In 1998, he took charge of the US CMS tracker group as a member of the UCSB faculty. He returned to CERN in 2007 to serve as deputy physics coordinator for CMS and has been at the laboratory full-time since then.

Higgs can run, but it can't hide

From Discovery News, March 29, 2011

The Higgs boson is a wily, elusive little particle, but scientists at both Fermilab and CERN are hot on its heels, and if recent experimental results are any indication, the Higgs is fast running out of places to hide -- at least the version of the Higgs predicted by the Standard Model of particle physics.

Let's check in with Fermilab's Tevatron first, shall we? As regular readers know, after decades of world-class research and pivotal discoveries, the Tevatron's days are numbered. Ongoing budget cuts mean the massive (four miles in circumference) accelerator in Illinois will shut down this fall. So scientists on the two main experiments there, CDF and DZero, are working overtime to pick up hints of this last missing piece to the particle physics puzzle.

Earlier this month, scientists with each of those collaborations presented new results that excludes key regions of the range of possible masses for the Higgs, based on additional data collected and more sophisticated techniques for analyzing that data. See, scientists aren't entirely sure where to look for the Higgs; the more they can narrow the target range, the better their chances of finally detecting its telltale signature.

There are two primary scenarios: one that involves a high-mass Higgs boson (heavier than 130 GeV, or giga-electron volts, up to around 600 GeV), and one that predicts a low-mass Higgs (between 114 GeV and 129 GeV). The latest results focused on the high-mass scenario, and based on those findings, Fermilab scientists say they now can exclude a Higgs with a mass between 158 and 173 GeV with about 95 percent certainty.

CDMS: The uncertainty principle for dark matter searches

CDMS inside the Soudan mine

As an undergraduate physics major, I was introduced to the Heisenberg uncertainty principle, which states that it is impossible to measure the exact momentum and position of an object at the same time. This is not caused by inadequacies in our experiments. Instead, it implies a fundamental limit to our ability to predict the future of a system because we cannot precisely determine its present state. Such a conclusion is shocking to any physicist. Even Einstein himself refused to accept it.

Shocking as the principle is, my university education at least prepared me for the uncertainty of the subatomic world. What I wasn’t taught was how much uncertainty is embedded in the day-to-day life of a physicist. A little over a week ago, the mine where my experiment is housed experienced a fire. The name of my experiment is the Cryogenic Dark Matter Search, or CDMS.

Before I tell you about the fire, let me explain the purpose of CDMS. Scientists have gathered a large body of evidence that tells us most of the matter in the universe is not in a form that we can see. Matter that we can see takes on the form of stars, planets, moons, comets, interstellar dust etc.. Dark matter is instead composed of a form of matter that we have never observed on Earth. My experiment is attempting to probe this dark matter component of the universe and will help us understand what dark matter is really made of. CDMS is located approximately 1 km, or a little more than half a mile, underground inside the Soudan Underground Laboratory – up near the Boundary Waters of northern Minnesota. This unusual location allows us to use the earth as a barrier to cosmic rays. These can produce signals that will confuse our attempts to observe dark matter.

So while housing the experiment deep underground is necessary for its function, it can make for some unexpected challenges. The day of the fire, I and my colleagues waited anxiously, hour-by-hour for the latest news on the attempts to extinguish it. Luckily, the fire was not in the lab, but was instead in the mine shaft. Since this shaft serves as the entry and exit to the laboratory, it was still quite a serious situation. In the end, the fire was put out after heroic efforts on the part of the Minnesota Department of Natural Resources, which operates the laboratory, and the various emergency responders. Thankfully no one was injured and the damage to the mine shaft and infrastructure were minimal compared to our initial fears. Since last week, the laboratory staff has been busy restoring power to the underground lab and assessing damage to the mine infrastructure. As of this Monday, a few scientists have finally been allowed restricted access to the lab. They are beginning to assess the status of CDMS.
