Exploring the dark sector with NA64

by Sergei Gninenko

NA64 experiment searches for dark photons that could provide hints for the dark content of our Universe

HIE-ISOLDE is tuning up for the new physics season

by Yacine Kadi (HIE-ISOLDE Project Leader) & Athina Papageorgiou Koufidou (HIE-ISOLDE)

HIE-ISOLDE reached another milestone with the addition of the third cryomodule.

Search for axions in streaming dark matter

by Horst Fischer (University of Freiburg, Germany), Yannis Semertzidis (Institute for Basic Science, Daejeon, Korea), Konstantin Zioutas (University of Patras, Greece)

A recent paper suggests that streaming dark matter (DM) axions may be the better source for discovering the candidate particles of one of the few fundamental open questions in physics

Exotic searches with NA62 experiment

by Panos Charitos

Apart from high-precision measurement of rare processes that could reveal new physics, the NA62 collaboration is also looking into the possibility of the existence of exotic particles.

MOEDAL first results at the LHC’s discovery frontier

by James Pinfold (MoEDAL Spokersperson, University of Alberta)

MoEDAL has finished an initial campaign of calibration and is now poised start to produce greatly enhanced results, with unparalleled sensitivity, using the full detector

First measurements of the antihydrogen spectrum

by Panos Charitos

ALPHA experiment observed the 1S-2S transition in trapped antihydrogen. This is the first time a spectral line has been observed in antihydrogen and the next steps are to measure the transition's lineshape and increase the precision of the measurement. 

A new experiment searching for dark matter at CERN

by Stefania Pandolfi

The NA64 experiment started operations at CERN’s North Area earlier this year hunting the hypothetical dark photon

On 28th September, the ISOLDE Collaboration celebrated the completion of stage 1 of the HIE-ISOLDE project, which opens up new physics opportunities for radioactive ion beam experiments at CERN.

ASACUSA Collaboration at CERN AD

by Ryugo Hayano on behalf of the ASACUSA collaboration

The ASACUSA experiment focuses on antihydrogen ground-state hyperfine splitting measurement and antiprotonic helium laser spectroscopy, both aiming at precise CPT tests.

The BASE Experiment

by Stefan Ulmer on behalf of the BASE Experiment

BASE collaboration, approved in 2013, will conduct Penning trap based high-precision investigations of the fundamental properties of protons and antiprotons providing stringent tests of the CPT symmetry.
