ATLAS finds evidence of a rare Higgs boson decay 8 Fevereiro, 2021
ATLAS finds evidence of a rare Higgs boson decay katebrad Mon, 02/08/2021 - 09:33 A collision event captured by the ATLAS detector in 2017 featuring a photon and two highly-collimated muons. The invariant mass of the dimuon pair is 0.6 GeV, and the invariant mass of the photon-plus-dimuon system is 124.9 GeV. The signature is […]
Potassium nucleus loses some of its magic 28 Janeiro, 2021
Potassium nucleus loses some of its magic Ana Lopes abelchio Thu, 01/28/2021 - 16:59 The magic seems to be ebbing away from some atomic nuclei. The latest measurements of the sizes of potassium nuclei rich in neutrons show no signature of a “magic” number of neutrons in potassium-51, which has 19 protons and 32 neutrons. […]

CMS sets new bounds on the mass of leptoquarks 17 Dezembro, 2020
CMS sets new bounds on the mass of leptoquarks Ana Lopes abelchio Thu, 12/17/2020 - 11:03 The CMS detector (Image: CERN) At the most fundamental level, matter is made up of two types of particles: leptons, such as the electron, and quarks, which combine to form protons, neutrons and other composite particles. Under the Standard […]

Welcome to the precision era By: Corinne Pralavorio 8 DECEMBER, 2020 Our sixth story in the LHC Physics at Ten series looks at the precision measurements of the Standard Model made at the Large Hadron Collider Bs0→ μ+μ- decay candidate event recorded in 2016 (Image: CERN) At the start of 2010, the particle physics community […]
Recreating Big Bang matter on Earth 12 Novembro, 2020
Recreating Big Bang matter on Earth By: Ana Lopes 13 NOVEMBER, 2020 · Voir en français Our fifth story in the LHC Physics at Ten series looks at how the LHC has recreated and greatly advanced our knowledge of the state of matter that is believed to have existed shortly after the Big Bang […]
A transportable antiproton trap to unlock the secrets of antimatter 3 Novembro, 2020
A transportable antiproton trap to unlock the secrets of antimatter Ana Lopes abelchio Tue, 11/03/2020 - 14:46 Shows the layout of the trap (Image: CERN) The BASE collaboration at CERN has bagged more than one first in antimatter research. For example, it made the first ever more precise measurement for antimatter than for matter, it […]
