Web10 Exercises: Higgs boson decays We consider in the following various two body decays of a Higgs boson. 10.1 Kinematics Let the Higgs boson of mass MH and momentum q decay into particles A and B of masses m1 and m2 and momenta p1 and p2 respectively: H(q) → A(p1) + B(p2). The decay rate summed over final polarisations and colours is: … WebClick on the 'Fire' button to see a Higgs boson decay into two photons along with a lot of background interactions. The aim is for you to try and identify the two photons, which can be used to calculate the mass of the Higgs boson. After several measurements, you can plot a line of best fit on the histogram to find the mass of the Higgs boson.

Web4 de jun. de 2024 · Geneva, 4 June 2024. The Higgs boson interacts only with massive particles, yet it was discovered in its decay to two massless photons. Quantum mechanics allows the Higgs to fluctuate for a very short time into a top quark and a top anti-quark, which promptly annihilate each other into a photon pair. Web2 de set. de 2024 · The incoming Higgs decays into a pair of massive particles.
