Lectures on LHC Physics
@inproceedings{Plehn2009LecturesOL, title={Lectures on LHC Physics}, author={Tilman Plehn}, year={2009} }
With the discovery of the Higgs boson the LHC experiments have closed the most important gap in our understanding of fundamental interactions. We now know that the interactions between elementary particles can be described by quantum field theory, more specifically by a renormalizable gauge theory. This theory is valid to arbitrarily high energy scales and do not require an ultraviolet completion. In these notes I cover three aspects to help understand LHC results in the Higgs sector and in…

The Higgs legacy of the LHC Run I
- Physics
- 2015
A bstractBased on Run I data we present a comprehensive analysis of Higgs couplings. For the first time this SFitter analysis includes independent tests of the Higgs-gluon and top Yukawa couplings,…
Beyond the Standard Higgs at the LHC: present constraints on Little Higgs models and future prospects
- Physics

The Large Hadron Collider (LHC) at CERN, at which protons collide at unprecedented center of mass energies and very high instantaneous luminosity, gives unique possibilities for precise tests of the…
The Status of Supersymmetry after the LHC Run 1
- Physics
- 2015
Supersymmetry (SUSY) is a complete and renormalisable candidate for an extension of the Standard Model. At an energy scale not too far above the electroweak scale it would solve the hierarchy problem…
Higgs from top to bottom : Discovery of the Higgs boson coupling to top quarks with the ATLAS detector
- Physics
- 2018
In the Standard Model (SM) of particle physics, it is expected that the Higgs boson as a scalar spin-0 particle gives mass to all other elementary particles. In addition, the coupling to the top…
Heavy to light Higgs boson decays at NLO in the singlet extension of the Standard Model
- Physics
- 2015
A bstractWe study the decay of a heavy Higgs boson into a light Higgs pair at one loop in the singlet extension of the Standard Model. To this purpose, we construct several renormalization schemes…
The Higgs mass and the scale of new physics
- Physics
- 2015
A bstractIn view of the measured Higgs mass of 125 GeV, the perturbative renormalization group evolution of the Standard Model suggests that our Higgs vacuum might not be stable. We connect the usual…
Higgs Pair Production at the LHC through the Flavon
- Physics
- 2022
The detection of a single Higgs boson at the Large Hadron Collider (LHC) has allowed one to probe some properties of it, including the Yukawa and gauge couplings. However, in order to probe the Higgs…
Synthesis on Heavy Higgs from the Standard Model to 2HDM and Beyond
- Physics
- 2020
: In the context of particle physics, within the ATLAS and CMS experiments at large hadron collider (LHC), this work presents the discution of discovery a particle compatible with the Higgs boson by…

The investigation of the dynamics responsible for electroweak symmetry breaking is one of the prime tasks of experiments at present and future colliders. Experiments at the Tevatron Collider and at…
Basics of QCD Perturbation Theory
- Physics

A prediction for experiment based on perturbative QCD combines • a particular calculation of Feynman diagrams (easy at leading order, not so easy at next-to-leading order). • use of general features…
Hard interactions of quarks and gluons: a primer for LHC physics

In this paper, we will develop the perturbative framework for the calculation of hard-scattering processes. We will undertake to provide both a reasonably rigorous development of the formalism of…
Measuring the Higgs sector
- Physics
- 2009
If we find a light Higgs boson at the LHC, there should be many observable channels which we can exploit to measure the relevant parameters in the Higgs sector. We use the SFitter framework to map…
Measuring supersymmetry

If new physics is found at the LHC (and the ILC) the reconstruction of the underlying theory should not be biased by assumptions about high-scale models. For the mapping of many measurements onto…
