Trans Day of Visibility 2026 - Egale Canada Every March 31st, the trans community and allies come together to observe Trans Day Of Visibility (TDOV)

March 31st marks the International Transgender Day of Visibility. SNOLAB values diversity in people and we work to create a welcoming environment. In science and society, there is much to gain when we embrace people for who they are. Learn more here: egale.ca/egale-in-act....

Thank you @laurentianu.bsky.social for another great Research Week! The SNOLAB community took part in a variety of ways, including an EDI poster and a 5-min research insight. Great to see such research excellence on display in our community!

SNOLAB was so excited to participate in the Ready, SETT, Go! event at Marymount Academy this morning! Our staff got to engage with student in speed networking and at a booth to learn more about what we do!

Big news coming from the BASE experiment at @cern.bsky.social after they successfully transport antimatter across CERN's main site! This is a huge step forward in the delivery of antimatter to other laboratories in Europe. Read more about this achievement here: home.cern/news/press-r...

New DEAP-3600 results from SNOLAB. Using 790.8 live-days of liquid argon data, we set stronger limits on WIMPs - one of the leading dark matter candidates - and improved our view of where this invisible matter is not hiding.🕵️

LHCb Collaboration discovers new proton-like particle The LHCb experiment at CERN’s Large Hadron Collider (LHC) has discovered a new particle consisting of two charm quarks and one down quark, a similar structure to the familiar proton, but with two heavy charm quarks replacing the two up quarks of the proton, thus quadrupling its mass. The discovery, presented at the ongoing Moriond conference, will help physicists better understand how the strong force binds protons, neutrons and other composite particles together. Quarks are fundamental building blocks of matter and come in six flavours: up, down, charm, strange, top and bottom. They usually combine in groups of twos and threes to form mesons and baryons, respectively. Unlike the stable proton, however, most of these mesons and baryons, which are collectively known as hadrons, are unstable and short-lived, making them a challenge to observe. Producing them requires smashing together high-energy particles in a machine such as the Large Hadron Collider (LHC). These unstable hadrons will quickly decay, but the more stable particles that are produced as a result of this decay can be detected and the properties of the original particle can therefore be deduced. Researchers have used this approach many times to find new hadrons, and the new particle just announced by the LHCb Collaboration brings the total number of hadrons discovered by LHC experiments up to 80. “This is the first new particle identified after the upgrades to the LHCb detector that were completed in 2023, and only the second time a baryon with two heavy quarks has been observed, the first having being observed by LHCb almost 10 years ago,” says LHCb Spokesperson Vincenzo Vagnoni. “The result will help theorists test models of quantum chromodynamics, the theory of the strong force that binds quarks into not only conventional baryons and mesons but also more exotic hadrons such as tetraquarks and pentaquarks.” In 2017, LHCb reported the discovery of a very similar particle, which consists of two charm quarks and one up quark. This up quark is the only difference between this particle and the new one, which has a down quark in its place. Despite the similarity, the new particle has a predicted lifetime that is up to six times shorter than its counterpart, due to complex quantum effects. This makes it even more challenging to observe. By analysing data from proton–proton collisions recorded by the LHCb detector during the third run of the LHC, the LHCb Collaboration observed the new baryon with a statistical significance of 7 sigma, well above the threshold of 5 sigma required to claim a discovery. “This major result is a fantastic example of how LHCb’s unique capabilities play a vital role in the success of the LHC,” says Mark Thomson, CERN Director-General. “It highlights how experimental upgrades at CERN directly lead to new discoveries, setting the stage for the transformative science we expect from the High-Luminosity LHC. These achievements are only possible thanks to the exceptional performance of CERN’s accelerator complex and the teams who make it all work and to the commitment of the scientists on the LHCb experiment.” Further information: LHCb presentation at Moriond is available here.

Global Physics Photowalk winners announced The Interactions Collaboration has announced the winning images of the 2025 Global Physics Photowalk. These photographs transform the invisible frontier of particle physics — from a detector hunting for dark matter a few thousandths of a degree above absolute zero, to a deep-sea neutrino telescope studying violent astrophysical phenomena — into visual testaments that capture the beauty, precision and nature of humankind’s search to understand the universe.

Congratulations to all the winners of the 2025 Global Physics Photowalk. SNOLAB was among 16 participating labs, contributing three images to the competition from local photographers. Thank you to everyone who participated and voted. View the results here: interactions.org/press-releas....
