Lecturer: DrDariaSokhan Room505,KelvinBuilding [email protected] RecommendedTexts: PartI:KennethS.Krane,“IntroductoryNuclearPhysics”,(Wiley), PartII:E.HenleyandA.Garcia,“SubatomicPhysics”(WorldScientific). 2 Assessment ThecoursewillbeassessedviaanexaminationintheApril/Maydiet.Itprovides10H-level credits. 3 RequiredKnowledge StudentsareexpectedtohavecompletedtheLevel4corecourseonPHYS4015Nuclearand Particle Physics. They should be familiar with the basics of the quark model and the shell model for the description of nuclei. They should also have completed and retained information from the Level 3 PHYS4025 Quantum Mechanics course and be familiar with operatorsandtheapplicationsoftheSchrödingerEquationtosimplepotentials. 4 IntendedLearningOutcomes By the end of the course, students will be able to demonstrate a knowledge and broad understanding of Nuclear and Hadron Physics. They should be familiar with the intrinsic propertiesofnucleons,nucleiandthenucleon-nucleonforce.Theyshouldbeabletomake calculations for the deuteron and understand and be able to operate with the mesonexchange interpretation of the nucleon-nucleon force. They should be familiar with the mainmodelsforheaviernuclei:theLiquidDropModel,theFermiGasModelandtheShell Model,andbeabletoexplainnuclearstructureintheirterms. Thestudentsshouldunderstandandbeabletooperatewiththemathematicalformalism of scattering, both using electrons and nucleons as a probe, and understand what can be learnedfromit.Theyshouldbefamiliarwiththequarkmodelandhadronsasaboundstate of quarks in low-energy Quantum Chromodynamics (QCD). They should understand what thehadronresonancespectrumis,howitcanbestudiedandwhatcanbelearnedfromit. They should be familiar with different types of electron scattering as a probe of quark distributionsinsidenucleons,specificallyelastic,deepinelasticanddeeplyvirtualCompton scattering,andbeabletoexplainwhathasbeenlearnedfromeach.Thestudentsshouldbe familiarwithanumberofexperimentaltechniquesandunderstandthebasicworkingsofa number of detectors in nuclear and hadron physics experiments. They should also have a basicunderstandingoftheprocessesofnuclei-synthesisinstars. 5 CourseOutline 5.1 PartI:Nuclearpropertiesandthenucleon-nucleonforce Thefirstpartofthecourseoutlinesthepropertiesofnucleiandtheirstructure.Itprovides anintroductiontotheintrinsicpropertiesofnucleonsandshowshowthoseofnucleiarise asaresultofthisandthenucleon-nucleonforce.Wewillstudythenucleon-nucleonforcein detailandapplyittothedescriptionofthesimplestboundstate:thatofthedeuteron.We will then introduce the meson-exchange interpretation of the force and learn to operate withit. 5.2 PartI:ElectronandNucleonScattering The formalism of scattering will be introduced in this section, both as nucleon-nucleon scattering(whichalsogivesinsightintothenucleon-nucleonforce)andaselectron-nucleus scattering,withexamplesofwhatcanbelearnedfromit. 5.3 PartI:Nuclearstructuremodels InthefinalsectionofPartI,wewilldiscussthemainnuclearstructuremodels(theLiquid DropModel,theFermiGasModelandtheShellModel),theirusesandlimitations. 5.4 PartII:Thequarkmodelandtheresonancespectrum Inthispartwewillzoomfurtherinonthenucleusandstudyindividualnucleonsandother hadrons in terms of QCD degrees of freedom. We will review the quark model and learn about the hadron resonance spectrum — what information it carries about nucleon structureandthethestrongforceandhowitcanbestudiedinexperiment.Wewillapply thistothecharmoniumresonancesasaspecialcasestudy. 5.5 PartII:Electronscatteringandpartondistributions We will then study in detail the processes of elastic electron scattering from nucleon targets, the process of deep inelastic scattering in general and deeply virtual Compton scattering in particular. We will discuss what has been learned about parton (quark and gluon) distributions from these types of experiments and the outstanding questions remaining. 5.6 PartII:ExperimentalTechniques Wewillreviewarangeofexperimentalscatteringtechniquesforstudyingthethenucleus andnucleons,includingbasicprinciplesofoperationforsomemaindetectorstypes. 5.7 PartII:NuclearAstrophysics Finally,wewillstudythemainprocessesofnucleosynthesisinstar-formation.
