Gauge Field Theories
Preface Introduction 1. Classical fields, symmetries and their breaking 2. Path integral formulation of quantum field theory 3. Feynman rules for Yang-Mills theories 4. Introduction to the theory ofExpand
Higgs Physics at the HL-LHC and HE-LHC
The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a landscape ofExpand
Curvature and isocurvature perturbations in two-field inflation
We study cosmological perturbations in two-field inflation, allowing for non-standard kinetic terms. We calculate analytically the spectra of curvature and isocurvature modes at Hubble crossing, upExpand
Gauge invariant effective Lagrangian for Kaluza-Klein modes
We construct a manifestly gauge invariant Lagrangian in $3+1$ dimensions for N Kaluza-Klein modes of an $\mathrm{SU}(m)$ gauge theory in the bulk. For example, if the bulk is $4+1,$ the effectiveExpand
Supersymmetrizing branes with bulk in five-dimensional supergravity
Abstract We supersymmetrize a class of moduli dependent potentials living on branes with the help of additional bulk terms in 5d N =2 supergravity. The resulting theories are gauged supergravitiesExpand
Stability of flux compactifications and the pattern of supersymmetry breaking
We extend the KKLT approach to moduli stabilization by including the dilaton and the complex structure moduli into the effective supergravity theory. Decoupling of the dilaton is neither alwaysExpand
Supersymmetry and FCNC effects
We consider Flavour Changing Neutral Current processes in the framework of the supersymmetric extension of the Standard Model. FCNC constraints on the structure of sfermion mass matrices areExpand
Theoretical uncertainties and phenomenological aspects of B → XSγ decay
Abstract We analyze uncertainties in the theoretical prediction for the inclusive branching ratio BR[ B → X s γ ]. We find that the dominant uncertainty in the leading order expression comes from itsExpand
Neutrino masses originate most likely at some high energy scale M≫MZ. To obtain reliable predictions for neutrino masses and mixing angles one has to take into account quantum corrections which, inExpand
Lepton-flavour violating B decays in generic Z ′ models
