Twice the charm: long-lived exotic particle discovered Piotr Traczyk cagrigor Thu, 07/29/2021 - 09:18 An artist’s impression of Tcc+, a tetraquark composed of two charm quarks and an up and a down antiquark (Image: CERN) Today, the LHCb experiment at CERN is presenting a new discovery at the European Physical Society Conference on High Energy […]
ATLAS reports first observation of WWW production 26 Julho, 2021
ATLAS reports first observation of WWW production cagrigor Mon, 07/26/2021 - 18:04 Display of a candidate WWW→ 3 leptons + neutrinos event. (Image: CERN) Today, at the EPS-HEP Conference 2021, the ATLAS collaboration announced the first observation of a rare process: the simultaneous production of three W bosons. As a carrier of the electroweak force, […]
Grabbing magic tin by the tail 22 Julho, 2021
Grabbing magic tin by the tail abelchio Thu, 07/22/2021 - 15:38 Atomic nuclei have only two ingredients, protons and neutrons, but the relative number of these ingredients makes a radical difference in their properties. Certain configurations of protons and neutrons, with “magic numbers” of protons or neutrons arranged into filled shells within the nucleus, are […]
MoEDAL bags a first 1 Julho, 2021
MoEDAL bags a first Ana Lopes abelchio Thu, 07/01/2021 - 16:29 The Monopole and Exotics Detector at the Large Hadron Collider (MoEDAL) does what it says on the tin. It searches for magnetic monopoles – hypothetical particles with either a “north” or a “south” magnetic charge instead of both – and other exotic theoretical particles. […]
Speeding up machine learning for particle physics 21 Junho, 2021
Speeding up machine learning for particle physics Ana Lopes abelchio Mon, 06/21/2021 - 14:52 An ultra-compressed deep neural network on a field-programmable gate array. (Image: Sioni P. Summers) Machine learning is everywhere. For example, it’s how Spotify gives you suggestions of what to listen to next or how Siri answers your questions. And it’s used […]
Leptoquarks, the Higgs boson and the muon’s magnetism 14 Junho, 2021
Leptoquarks, the Higgs boson and the muon’s magnetism Ana Lopes abelchio Mon, 06/14/2021 - 14:44 Zoom into an online particle physics conference, and the chances are you’ll hear the term muon anomaly. This is a longstanding tension with the Standard Model of particle physics, seen in the magnetism of a heavier cousin of the electron […]
ALICE finds that charm hadronisation differs at the LHC 10 Junho, 2021
ALICE finds that charm hadronisation differs at the LHC Andrea Dainese cagrigor Thu, 06/10/2021 - 14:13 Installation of the Outer Barrel of the new silicon Inner Tracking System of ALICE inside the solenoidal magnet. (Image: CERN) Quarks are among the elementary particles of the Standard Model of Particle Physics. Besides up and down quarks, which […]
LHCb measures tiny mass difference between particles 8 Junho, 2021
LHCb measures tiny mass difference between particles Ana Lopes abelchio Tue, 06/08/2021 - 08:57 The LHCb collaboration has measured a difference in mass between two particles of 0.00000000000000000000000000000000000001 grams – or, in scientific notation, 10-38 g. The result, reported in a paper just submitted for publication in the journal Physical Review Letters and presented today at […]
FASER catches first candidate collider neutrinos 2 Junho, 2021
FASER catches first candidate collider neutrinos Ana Lopes abelchio Wed, 06/02/2021 - 15:24 It’s a first at the Large Hadron Collider (LHC), or indeed at any particle collider: the FASER collaboration has detected the first candidate particle interactions for neutrinos produced in LHC collisions. The result, described in a paper posted online, paves the way […]
