Cern supercollider news1/27/2024 And as Russian institutes are getting excluded from international projects, some fields see a direct impact – such as climate change research, which is being set back by the suspension of collaboration in the Arctic. There have been reports of individual peer-review referees rejecting articles. The Web of Science database tracking citations has stopped evaluating articles from Russia. ![]() The German Research Foundation has warned scientists against publishing with co-authors from Russian institutes. If these collapse, then there is no legal basis for them to work in Switzerland and yet some have signed open letters protesting the war.” He explains that the termination of observer status in 2024 provides coverage until then, in the hope of a permanent diplomatic solution, but calls for the overall “protection of the scientists”.Īlthough unique, the case of the LHC experiments is part of a wider trend. A Cern spokesperson says that “the measures address, which runs against the values of peaceful collaboration”, adding that “the decision leaves the door ajar for peaceful scientific collaboration should conditions allow in the future.”Īccording to John Ellis, a professor at King’s College London and veteran theoretical physicist at Cern: “Russians working at Cern are covered by international cooperation agreements. Last spring, the Cern council decided to terminate the Russian Federation’s observer status and the cooperation agreements with Belarus when they expire in two years (Ukraine is an associate member of Cern, whose regular members comprise 22 European states and Israel, with cooperation extending to several dozen countries worldwide). As for the funding agencies, if they are not acknowledged, “I can tell you… that they will not react very positively.” However, a senior scientist at the LHC from outside Europe says: “Keep this political approach for some time and it can create problems for students, postdocs and for ourselves.” Brajesh Choudhary, professor at the University of Delhi and member of Cern’s CMS detector experiment, says: “If you don’t publish for the next few months the PhD students, postdocs and young faculty will face many problems.” From discussions with my Russian colleagues, nobody can accept what Russia is doing in Ukraine Fedor RatnikovĬhoudhary points out that articles without names and institutions may be acceptable within the experiments, but not by outside scientists and faculty, and that institutions care about mentions as these provide their ranking. Scientists from European countries and the US say that so far there has been little impact on funding or awarding PhDs. Where in the past this list would take up several pages, now there is a general attribution, eg “the Atlas collaboration”. Public versions are uploaded to the arXiv preprint server, but both they and the submissions to journals lack a list of authors and funding agencies. The unpublished pipeline now includes more than 70 pieces. ![]() Since March, the four LHC experiments have kept preparing new articles, sending them to journals for peer review and freezing their publication. Eleni PetrakouĪndreas Höecker, spokesperson for the Atlas experiment, emphasises that the issue is “solely related to the form of the institutional acknowledgment, given the statements of high-level representatives of Russian academic institutions… and the links of high-level funding bodies with the Russian government”. The LHC does not collide protons alone, but also the nuclei of lead atoms, creating a state similar to that in the moment after the Big Bang. In previous years, ALICE (A Larger Ion Collider Experiment) has studied this “quark-gluon plasma” it is now setting out to analyse the data. Since last summer the LHC conducts a larger number of collisions of protons at a higher energy, and researchers plan to see whether the discrepancies will solidify and uncover clues about them. The LHCb experiment was built to look deeper at tiny differences between matter and antimatter involving the so-called beauty quark, one of the biggest enigmas in the current model. ![]() Anything that differs from the Standard Model’s predictions would be a welcome arrival, particularly after years of no evidence of other proposed theories which complement the SM, such as supersymmetry. After establishing its presence a decade ago, scientists are still exploring how it interacts with other particles. The four big experiments at the Large Hadron Collider are devoted to the study of the Standard Model – the theory currently describing the smallest building blocks of the world – and, most importantly, of any deviations from it that might emerge.įor Atlas and CMS, the two “general purpose” workhorses, the properties of the Higgs boson are the new unknown.
