Wanted: SUSY particle still at large
– According to classical electrodynamics, the electromagnetic energy (and mass) of a point-like electron should be infinite. This is of course not the case! The solution of the riddle is antimatter - the ‘vacuum’ around every electron is filled with a cloud of electrons and anti-electrons and the combined energy turns out to be finite.Read more →
One does not simply give a talk at Moriond
– The third day of the Moriond QCD conference was dedicated to quantum chromodynamics (QCD), the theory that describes strong interactions itself.Read more →
Bumps in the light
– Here we are at the second blog from the Moriond QCD conference and, as promised, I will discuss a bit of physics.Read more →
Spring awakening for the ATLAS experiment
– This morning the Large Hadron Collider (LHC) circulated the first proton-proton beams of 2016 around its 27 kilometre circumference. The beams were met with great enthusiasm in the ATLAS Control Centre as they passed through the ATLAS experiment.Read more →
First impressions from the Moriond conference
– My name is Mario Campanelli, and I am a physicist who has been working for about 9 years on the ATLAS experiment, as part of the academic staff of University College London. This is the first time I write a blog, but I do have quite an experience in communicating science to the public, having guided visitors around CERN since I started working there as a PhD student 20 years ago, and also having written two books for the general public. Since Saturday I have been in La Thuile, a mountain resort in the Italian Alps, for the Rencontres de Moriond - arguably the most important winter conference in particle physics.Read more →
Searching beyond the Standard Model with photon pairs
– The ATLAS Collaboration uses two selections in this search, one optimised for Higgs-like particles that are expected to have a strong signal compared to background with both photons in the central region of the detector (the “spin-0” selection) and a second optimised for graviton-like particles (the “spin-2” selection) which often have at least one photon close to the LHC proton beam axis.Read more →
Chasing after elusive B meson decays into muons
– Almost four years following the discovery of the Higgs boson, LHC experiments are now more than ever exploring the possibility of new particles and new effects beyond the Standard Model.Read more →
Are there more Higgs bosons?
– The results presented by the ATLAS collaboration during the Moriond Electroweak 2016 conference set new limits on a potential extended Higgs sector.Read more →
ATLAS presents new results at Moriond conference
– This year’s 50th anniversary edition of the “Moriond Electroweak and Unified Theories” conference at La Thuile in Italy featured the presentation and discussion of first results from the LHC full-year 2015 data samples (“Run 2”) collected by the LHC experiments at unprecedented 13 TeV proton-proton collision energy.Read more →
Meet 7 inspiring women from the ATLAS experiment
– Women play key roles in the ATLAS Collaboration: from young physicists at the start of their careers to analysis group leaders and spokespersons of the collaboration. Celebrate International Women’s Day by meeting a few of these inspiring ATLAS researchers.Read more →
