The LHCb experiment is charmed to announce observation of a new particle with two heavy quarks

Geneva, 6 July 2017. Today at the EPS Conference on High Energy Physics in Venice, the LHCb experiment at CERN’s Large Hadron Collider has reported the observation of Ξcc++(Xicc++) a new particle containing two charm quarks and one up quark. The existence of this particle from the baryon family was expected by current theories, but physicists have been looking for such baryons with two heavy quarks for many years.

Lithuania to become Associate Member of CERN

Vilnius, 27 June 2017. Today, in Vilnius, Lithuania, CERN Director General, Fabiola Gianotti, and the Minister of Foreign Affairs of the Republic of Lithuania, Linas Linkevičius, in the presence of the President of the Republic of Lithuania, Dalia Grybauskaitė, signed the Agreement admitting Lithuania as an Associate Member of CERN. The last step for the Agreement to enter into force requires final approval by the Government of Lithuania.

Two new teams of high-school physicists selected to run experiments at CERN

CERN today announced the winners of its 2017 Beamline for Schools competition. “Charging Cavaliers” from Canada and “TCO-ASA” from Italy were selected from a total of 180 teams from 43 countries around the world, adding up to about 1500 high-school students. The winners have been selected to come to CERN in September to carry out their own experiments using a CERN accelerator beam.

Pioneering SESAME light source officially opened

Allan, Jordan, 16 May 2017. The SESAME light source was today officially opened by His Majesty King Abdullah II. An intergovernmental organization, SESAME is the first regional laboratory for the Middle East and neighbouring regions The laboratory’s official opening ushers in a new era of research covering fields ranging from medicine and biology, through materials science, physics and chemistry to healthcare, the environment, agriculture and archaeology.

CERN celebrates completion of Linac 4, its brand new linear particle accelerator

At a ceremony today, CERN inaugurated its linear accelerator, Linac 4, the newest accelerator acquisition since the Large Hadron Collider (LHC). Linac 4 is due to feed the CERN accelerator complex with particle beams of higher energy, which will allow the LHC to reach higher luminosity by 2021. After an extensive testing period, Linac 4 will be connected to CERN’s accelerator complex during the upcoming long technical shut down in 2019-20. Linac 4 will replace Linac 2, which has been in service since 1978. It will become the first step in CERN’s accelerator chain, delivering proton beams to a wide range of experiments.
