Going where the beam is good

From, July 25, 2012

This has been a fantastic year for high-energy physics. The long wait for the Higgs boson appears, finally, to be over, and with CERN's Large Hadron Collider (LHC) churning out unprecedented numbers of data, more discoveries seem just around the corner. But for some members of the community, these successes are bittersweet. The closure of the Tevatron collider – once an American rival to Europe's LHC – in September 2011 signalled the end of an era for particle physics in the US, and forced many researchers at Fermilab, the Tevatron's home, to rethink their career plans. Should they change fields? Move to CERN and the LHC? Or just get used to flying across the Atlantic a lot?

I travelled to Fermilab and CERN to learn more about the changing geography of high-energy physics and how it affects individual researchers. In this behind-the-scenes podcast, you'll hear senior scientists and early-career researchers talking candidly about their working lives, their reactions to the Tevatron's shutdown and their plans for the future.

Cuts loom for US science

From Nature, July 24, 2012

In an ordinary year, a flat budget for the US National Institutes of Health (NIH) would be considered dire news. This year, it is far from the worst possible outcome. Hanging over the effective decrease in support proposed by the House of Representatives last week is the 'sequester', a pre-programmed budget cut that research advocates say would starve US science-funding agencies.

A sharply divided Congress is showing few signs that it can defuse the situation before the self-imposed fiscal time bomb explodes, in less than six months' time. And even if Congress does manage to introduce last-minute legislation, as many observers expect, the sequester will have cast a shadow over the contentious process of funding science in a time of fiscal constraints — and in an election year.

The sweeping cut, scheduled to take effect on 2 January, is a by-product of last year's Budget Control Act, which requires law-makers to find ways to reduce the federal deficit (see Nature 476, 133-134; 2011). When a congressional committee failed in its remit to do just that last November, the clock began ticking towards an automatic cut that will claw the required amount from across the federal government, including all military and non-military spending that is not required by law. The precise amount to be cut depends on several variables, including tax revenue, but an estimate by the Congressional Budget Office puts it at 7.8% in 2013 for the non-military component.

The best of the best in Higgs bosons to b quarks

The curves show the observed (expected) upper 95% confidence limits as solid dots (dashed line) on the Higgs boson production cross section relative to the Standard Model expectation as a function of the Higgs boson mass.

With the observation of a Higgs-like boson in photon and Z boson states at the Large Hadron Collider, the two questions one should ask next are "How Standard Model-like is it?" and "How can other experiments contribute to our knowledge of this new particle?" If this new particle is the Standard Model Higgs boson, it should decay into a pair of b quarks more often than into any other final state. The most sensitive search to date for a Standard Model Higgs boson decaying to b quarks uses the combined power of the CDF and DZero searches for the production of Higgs bosons in association with Z and W bosons, which was reported two weeks ago. The most sensitive among these searches is the CDF search for a Higgs in association with a W (WH).

At the Tevatron and LHC, b jets are produced in large amounts, drowning out the expected signal of a Standard Model Higgs boson decaying to two b quarks. The most successful way to search for a Higgs boson in this final state is to look for Higgs bosons produced in association with a W boson that decays into a neutrino and an electron or muon. This is because the background for this kind of process is far more favorable. The CDF WH search analysis uses the full data sample from Tevatron Run II. We expect about 40 signal events and 33,000 background events after basic selection requirements. The small signal and large background require that we record every event that is a candidate for a Higgs produced with a W boson, and that the most signal-like events be separated from the rest.

To accomplish this, the CDF WH team separates the events into 26 different categories. Each category has different background compositions, each comprises some fraction of the total signal and each is an analysis in itself. The work of more than a dozen analyzers converged to more than double the expected sensitivity of this analysis in comparison to the same search from CDF in 2007. The results show a signal-like excess over the background-only expectation. The excess is not significant enough to claim discovery, but is suggestive that the particle observed at the LHC is not only Higgs boson-like, but is very Standard Model-Higgs boson-like.
