Here’s a roundup of recent CERN-related news:
- The status of the LHC and the LHC experiments was discussed here yesterday. The LHC shutdown is more or less on track, first beams at 13 TeV total energy Jan. 2015, physics starting April 2015.
- Both ATLAS and CMS have announced new data on tau-tau decays of the Higgs, providing stronger evidence for this signal than was available earlier. ATLAS sees a signal with significance 4.1 sigma, CMS at 3.4 sigma. These results are consistent with the SM, and rule out some SUSY alternatives in which the Higgs would behave differently. The Register headlines this Exotic physics takes an arrow to the knee.
- Not CERN related, but the last month or so has seen other new results ruling out some SUSY and other SM-alternatives. A good place to follow this is at Resonaances, where Jester discusses the LUX result on dark matter, and the new limits on the electron EDM.
- Plans are being made for long-term preservation of LHC data, keeping it in a usable form for the future. Nature has a story here, this this presentation has more detail.
- Meanwhile, CMS has a pilot project going to make some data available publicly in a form that can be accessed by high-school students.
- CERN DG Heuer has this announcement about activities of the FCC (Future Circular Colliders) study group looking into prospects for a large lepton collider (TLEP) as well as a higher energy hadron collider post-LHC.
- The CERN-sponsored SCOAP3 open access publishing initiative will start operation next month. From their web-site, it appears the idea is to spend up to 10 million euros/year, mostly going to commercial publishers to finance their journals that publish HEP papers. In return the papers (almost all of which were already accessible on the arXiv) will be “open access”. The publishers will get paid a per-article charge, so will have a serious incentive to publish as many articles as they can. I don’t see a document explaining exactly how the money will be spent, but for some idea of where it will go, see this list. It indicates that the two big recipients will be Elsevier (with 1300 or so papers/year in Physics Letters B and Nuclear Physics B, at around $2000 per paper) and some combination of Springer and SISSA where about 1650 JHEP papers will cost 1200 Euros each. I gather that in return for this the journals will reduce or eliminate subscription charges, but don’t know the details.
