Current approaches to detect dark matter

by
Les approches actuelles pour détecter la matière noire

IN BRIEF Detection of dark matter: innovative approach based on Josephson junctions. Exploration of gravitational waves to identify dark matter. Search for axions, potential candidates for dark matter, via their conversion into photons. Clear strategies: to do, see oneself undone, or look for its shakes. Study of neutron stars, potential keys in the detection of … Read more

Elementary particles: quarks, leptons, and bosons

by
Les particules élémentaires : quarks, leptons et bosons

IN BRIEF Elementary particles: fundamental units of matter. Quarks: components of protons and neutrons, grouped into hadrons. Leptons: particles such as electrons, without color charge. Standard model: theoretical framework encompassing particles and their interactions. Bosons: mediators of fundamental forces (e.g., the Higgs boson). Classification of particles into fermions (quarks and leptons) and bosons. Particle interaction: … Read more
