59 new hadrons and counting 2 Março, 2021
59 new hadrons and counting Piotr Traczyk abelchio Tue, 03/02/2021 - 13:47 How many new particles has the LHC discovered? The most widely known discovery is of course that of the Higgs boson. Less well known is the fact that, over the past 10 years, the LHC experiments have also found more than 50 new […]
28th International Workshop on Weak Interactions and Neutrinos 1 Março, 2021
28th International Workshop on Weak Interactions and Neutrinos anschaef Mon, 03/01/2021 - 10:56 The goal of the 28th International Workshop on Weak Interactions and Neutrinos (WIN 2021) is to offer to the community a significant opportunity to assess the status of the field and to initiate collaborative efforts to address current physics questions. Following up […]
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 […]
