LHC experiments eliminate more Higgs hiding spots
Two experimental collaborations at the Large Hadron Collider, located at CERN laboratory near Geneva, Switzerland, announced today that they have significantly narrowed the mass region in which the Higgs boson could be hiding.
The ATLAS and CMS experiments excluded with 95 percent certainty the existence of a Higgs over most of the mass region from 145 to 466 GeV. They announced the new results at the biennial Lepton-Photon conference, held this year in Mumbai, India.
“Each time we add new data to our analyses, we close in more on where the Higgs might be hiding,” said Darin Acosta, a University of Florida professor and deputy physics coordinator for the CMS experiment.
More than 1,700 scientists, engineers and graduate students from the United States collaborate on the experiments at the LHC, most of them on the CMS and ATLAS experiments, through funding by the Department of Energy Office of Science and the National Science Foundation. Brookhaven National Laboratory serves as the U.S. base for participation in the ATLAS experiment, and Fermi National Accelerator Laboratory serves as the U.S. base for participation in the CMS experiment.

Dark Energy Camera imager is ready (George is doing well)
DES first-light countdown, 6 months to go
I have promised to provide updates on our progress towards the first light of the Dark Energy Survey’s, or DES. First light is the first official look at the sky after readying the camera and its detection software. If you recall, we were supposed to deliver the Dark Energy Camera, or DECam, imager this summer.
So, without further ado, I am pleased to announce: Here it is!
I have been collecting DES-related pictures and videos for a while and the picture to right by Fermilab photographer Reidar Hahn is by far my favorite shot of the imager (first published in Fermilab Today). It shows the focal plane completely populated with 74 shiny, blue CCDs, ready to catch some extragalactic photons.
Shipment arrangements and installation schedule are being worked out as I write. Our team has already set foot in Chile to assemble at the Blanco Telescope the various parts that we tested on our Fermilab telescope simulator in February. Installation will start soon.
Q&A with Brian Cox, part 2: Space exploration and hope
From Universe Today, Aug. 17, 2011
Professor Brian Cox is the Chair in Particle Physics at the University of Manchester, and works on the ATLAS experiment (A Toroidal LHC ApparatuS) at the Large Hadron Collider at CERN. But he’s also active in the popularization of science, specifically with his new television series and companion book, Wonders of the Universe. Universe Today had the chance to talk with Cox, and yesterday he told us about the recent advances in particle physics. Today we ask him about his favorite space missions and his hopes for the future of science.
For a chance to win a copy of the “Wonders of the Universe” book, see our contest post.
Universe Today: The Juno mission just launched to Jupiter and there are lots of other space missions going on. What are some your favorites and your hopes of what those kinds of missions will discover?
Brian Cox: The enormous question for space exploration is origin of life on other worlds. That is currently THE big question. We’ve seen discoveries recently about possible, plausible evidence of flowing water on Mars. There’s been evidence for awhile that there is perhaps subsurface water. but seeing what looks to be the signature of flowing, briny water — today — is very suggestive. On Earth, where we have water we have life, so this new finding makes Mars even more fascinating.
How to protect your personal protective equipment

Choosing the right personal protective equipment (PPE) is an important step toward ensuring your safety. But you need to care for that equipment to ensure it can protect you. Here are some guidelines for keeping your equipment in good working order.
Promptly replace hardhats, helmets and bump caps if damaged or defective. Inspect them daily, asking yourself the following questions:
- Are inside straps adjusted and working properly?
- Is the outer shell cracked or dented?
- Are the chin straps frayed or split, compromising their ability to hold the hardhat on your head?
- Is your hardhat clean? Use a damp rag with mild soap and water to clean your hardhat every couple of days.
Wearing safety glasses or goggles helps protect your eyesight. Having a proper fit and keeping them clean is key. If they are cracked, scratched or broken, have them replaced.
Using hearing protection is necessary to protect from hearing loss. Use the PPE appropriately and like all PPE, keep it clean. Use single-use ear plugs only once. Re-usable earplugs, canal caps and ear muffs must be cleaned on a regular basis.
Proper hand protection can prevent cuts, burns and other injuries. Selecting the right type of glove and understanding when they should be used will help keep your hands safe. If you're not sure what type of glove to use for the job, ask your senior safety officer (SSO) or your supervisor.
Caring for your foot protection is a daily requirement. Check the soles, laces and eyelets of your shoes for wear. Also, make sure they are free of contaminants such as oil or grease, which could eliminate their ability to provide traction.
For more information on PPE, contact your supervisor or SSO.
