ATLAS and CMS experiments present Higgs search status

13 December 2011. In a seminar held at CERN today, the ATLAS and
CMS experiments presented the status of their searches for the
Standard Model Higgs boson. Their results are based on the
analysis of considerably more data than those presented at the
summer conferences, sufficient to make significant progress in
the search for the Higgs boson, but not enough to make any
conclusive statement on the existence or non-existence of the
elusive Higgs. The main conclusion is that the Standard Model
Higgs boson, if it exists, is most likely to have a mass
constrained to the range 116-130 GeV by the ATLAS experiment, and
115-127 GeV by CMS. Tantalising hints have been seen by both
experiments in this mass region, but these are not yet strong
enough to claim a discovery.

Весь день насиловал осциллограф, два раза уронил explorer, жестоко насиловал 79k файлов в одной директории, и под конец дня он начал таки конкретно глючить. А ещё с него можно писать в жуйк и коллекционировать вирусы, если подключить к сети.

CERN supports European Year of Volunteering through Citizen Cyberscience Centre

Geneva, 8 August 2011. Today, researchers at CERN began public testing of a new version of the popular volunteer computing project LHC@home[1]. This version allows volunteers to participate for the first time in simulating high-energy collisions of protons in CERN’s Large Hadron Collider (LHC). Thus, volunteers can now actively help physicists in the search for new fundamental particles that will provide insights into the origin of our Universe, by contributing spare computing power from their personal computers and laptops. This is just one example of a series of projects and events organized by the Citizen Cyberscience Centre[2], a partnership between CERN, UNITAR (the UN Institute for Training and Research) and the University of Geneva, to promote volunteer-based science in this, the European Year of Volunteering 2011[3].

At least one person has relayed the speculation that the animals are primarily present to allay local’s fears of radiation: if sheep can spend all day snacking on top of an accelerator then how dangerous can it be? The problem I have with this theory is that it makes no mention of the scientists who spend just as much time in just as much proximity to our scary science stuff. Does the public honestly think we are so driven to distraction by our whizzing particles that we might very well hang our balls in the beam to see if it tickles? Let me go on record and say definitively, no, we are not.

Geneva, 7 July 2011. Four months after launching the alpha version, CERN has today issued version 1.1 of the Open Hardware Licence (OHL), a legal framework to facilitate knowledge exchange across the electronic design community.

In the spirit of knowledge and technology dissemination, the CERN OHL was created to govern the use, copying, modification and distribution of hardware design documentation, and the manufacture and distribution of products. Hardware design documentation includes schematic diagrams, designs, circuit or circuit-board layouts, mechanical drawings, flow charts and descriptive texts, as well as other explanatory material.

Version 1.0 of the CERN OHL was published in March 2011 on the Open Hardware Repository (OHR), the creation of electronic designers working in experimental-physics laboratories who felt the need to enable knowledge-exchange across a wide community and in line with the ideals of "open science" being fostered by organizations such as CERN.

"For us, the drive towards open hardware was largely motivated by well-intentioned envy of our colleagues who develop Linux device-drivers," said Javier Serrano, an engineer at CERN’s Beams Department and the founder of the OHR. "They are part of a very large community of designers who share their knowledge and time in order to come up with the best possible operating system. We felt that there was no intrinsic reason why hardware development should be any different.”
