Let’s have a coffee with the Standard Model of particle physics!

Abstract

The Standard Model of particle physics is one of the most successful theories in physics and describes the fundamental interactions between elementary particles. It is encoded in a compact description, the so-called 'Lagrangian', which even fits on t-shirts and coffee mugs. This mathematical formulation, however, is complex and only rarely makes it into the physics classroom. Therefore, to support high school teachers in their challenging endeavour of introducing particle physics in the classroom, we provide a qualitative explanation of the terms of the Lagrangian and discuss their interpretation based on associated Feynman diagrams.

Jogo de Física de partículas: Descobrindo o bóson de Higgs

“…Novas condições metodológicas relacionadas à Física de Partículas precisam ser implementadas tanto a nível de graduação como a nível básico de ensino para que essa temática possa estar presente na prática diária docente. Podemos ver que na Europa, onde está localizado o LHC, vários pesquisadores estão elaborando propostas para ensinar Física de altas energias e inserir as partículas elementares no universo dos estudantes [63][64][65].…”

“…It is proposed in modelling the components of a by-product carrier wave. Description of particles is important and several proposals have been made [8][9][10][11]. The atomic process has been suggested to be modelled through the use of exterior algebras [12].…”

“…The current model describing Nature's fundamental particles and their interactions is called the Standard Model [1,[4][5][6][7][8]. The framework of the theory is a quantum field theory [8].…”

“…With the high-precision detector modules of the VELO, the IPs of tracks and subsequent displacement of vertices formed by combinations of these tracks can be measured. 1 Operating at the Z 0 boson mass would also work 2 i.e. charged (pseudo)stable particles: e ± , µ ± , π ± , K ± , p and p. 3 the distance of closest approach of the extrapolated track with respect to the PV.…”

“…To understand the workings of Nature, it is not only necessary to model and describe all we see around us, but also to explore phenomena beyond the reach of our senses in order to measure and deduce Nature's fundamental properties and laws, from which our direct environment emerges. In the 20th century, physicists have developed a very successful theory called the Standard Model, to describe all known fundamental particles and their interactions, aside from gravity [1]. The Standard Model is able to describe Nature down to very small length scales and up to high energies.…”
