Elementary particles

Atom Electron:elementary, point-particle

Protons and neutrons: Composite particle ⇒ quarks

Electro-magnetic force binds electrons to nucleus in atom (Quantum-Electrodynamics)

Strong force binds nucleons in nucleus and quarks in nucleons (Quantum-Chromodynamics)

Bacheloronderzoek SAP

• Data-analyse – Flow-metingen – Reconstructie van zware-quark deeltjes – Jet-reconstructie

• Modelleren van botsingsprocessen – Bijv. Hydrodynamica, gluonstraling in een quark-gluonplasma

• Detectorontwikkeling (testopstelling voor nieuwe detectoren) – Silicon pixel detector (verbeteren van reconstructie van zware-quark deeltjes)

– Forward calorimeter (fotonenmetingen)

Precieze onderwerp in overleg

NB: meeste onderwerpen computerintensief; voorkennis (op dit gebied) niet nodig; onderdeel van het onderzoek

Vaardigheden (Wat bieden wij?)• Data-analyse

– Programmeren – Numerieke methoden – Handling huge amount of data

• Detectorontwikkeling – Elektronica en material science – Medical imaging (samenwerking met UMC):

e.g., botstructuur en mammografie – HiSparc project (meten van kosmische straling)

• Skills – ALICE Collaboratie: Groote samenwerkingsverband – Teamwork – International omgeving

Het Standaard Model

Het standaard model is de basis van de moderne deeltjesfysica

wel nog open vragen:

bijv. massa van deeltjes: Higgs deeltjes

ook sterke wisselwerking (quarks en gluonen) heefd een aantal radsels
