These lectures are divided into two parts. In Part 1 I discuss bound state topics at the level of a basic course in field theory: The derivation of the Schr\"odinger and Dirac equations from the QED Lagrangian, by summing Feynman diagrams and in a Hamiltonian framework. Less well known topics include the equal-time wave function of Positronium in motion and the properties of the Dirac wave function for a linear potential. The presentation emphasizes physical aspects and provides the framework… Expand
Lectures on Bound states
Even a first approximation of bound states requires contributions of all powers in the coupling. This means that the concept of "lowest order bound state" needs to be defined. In these lectures IExpand
Dark Matter Bound State Formation for PseudoScalar Mediators
Self-interacting dark matter is a popular and active field of research, it produces a rich phenomenology, and gives unique signals that we can search for. This thesis is devoted to the topic of darkExpand
Light-front holographic QCD and emerging confinement
Abstract In this report we explore the remarkable connections between light-front dynamics, its holographic mapping to gravity in a higher-dimensional anti-de Sitter (AdS) space, and conformalExpand
Dark-matter bound states from Feynman diagrams
A bstractIf dark matter couples directly to a light force mediator, then it may form bound states in the early universe and in the non-relativistic environment of haloes today. In this work, weExpand
Born Level Bound States
Bound state poles in the S-matrix of perturbative QED are generated by the divergence of the expansion in $$\alpha $$α. The perturbative corrections are necessarily singular when expanding aroundExpand
Gravitino condensation, supersymmetry breaking and inflation
Motivated by dualistic considerations of the reality of quark condensation in quantum chromodynamics, and the connections of supergravity to the exotic physics of string and M-theory, in this thesisExpand
The physical spectrum of theories with a Brout-Englert-Higgs effect
The physical, observable spectrum in gauge theories is made up from gauge-invariant states. In the standard model of particle physics the Fröhlich-Morchio-Strocchi mechanism shows that these statesExpand
Nucleon - Nucleon Interactions at Short Distances
Despite the progress made in understanding the NN interactions at long distances based on effective field theories, the understanding of the dynamics of short range NN interactions remains as elusiveExpand
Confinement with Perturbation Theory, After All?
I call attention to the possibility that QCD bound states (hadrons) could be derived using rigorous Hamiltonian, perturbative methods. Solving Gauss’ law for A0 with a non-vanishing boundaryExpand
Radiative bound-state-formation cross-sections for dark matter interacting via a Yukawa potential
A bstractWe calculate the cross-sections for the radiative formation of bound states by dark matter whose interactions are described in the non-relativistic regime by a Yukawa potential. TheseExpand


Towards a Born term for hadrons
potential is determined by a boundary condition in the solution of Gauss’ law for the instantaneous A 0 eld. As in the case of the Dirac equation, the norm of the relativistic fermion-antifermion (fExpand
The wave functions of moving bound states may be expected to contract in the direction of motion, in analogy to a rigid rod in classical special relativity, when the constituents are at equalExpand
Boosting equal time bound states
We present an explicit and exact boost of a relativistic bound state defined at equal time of the constituents in the Born approximation (lowest order in hbar). To this end, we construct theExpand
Bound states at lowest order in hbar
Bound states poles in scattering amplitudes are generated by the divergence of the perturbative series due to enhanced Coulomb scattering near thresholds. This suggests to organize bound stateExpand
Strong QCD and Dyson-Schwinger Equations
The real-world properties of quantum chromodynamics (QCD) - the strongly-interacting piece of the Standard Model - are dominated by two emergent phenomena: confinement; namely, the theory'sExpand
Hydrogen Atom in Relativistic Motion
The Lorentz contraction of bound states in field theory is often appealed to in qualitative descriptions of high energy particle collisions. Surprisingly, the contraction has not been demonstratedExpand
Boost operators in Coulomb gauge QCD: The pion form factor and Fock expansions in $ \phi$ radiative decays
In this article we re-derive the Boost operators in Coulomb Gauge Yang-Mills theory employing the path integral formalism and write down the complete operators for QCD. We immediately apply them toExpand
States of the Dirac equation in confining potentials.
We study the Dirac equation in confining potentials with pure vector coupling, proving the existence of metastable states with longer and longer lifetimes as the nonrelativistic limit is approachedExpand
XYZ States - Results from Experiments
Charmonium(-like) or bottomonium(-like) states, which are incompatible with predictions from a static quark anti-quark potential model, are often refered to as XYZ states. In this lecture, someExpand
Quantum Theory of Fields
To say that this is the best book on the quantum theory of fields is no praise, since to my knowledge it is the only book on this subject. But it is a very good and most useful book. The original wasExpand
