Abstract: The search for BSM physics is the main focus of todays
high-energy physics. We will discuss two examples for direct and
indirect BSM searches. Both examples show an interesting discrepancy
with the SM prediction. (i) Direct searches for light Higgs bosons
show two excesses at ~96 GeV. We analyze these excesses in the
Two-Higgs-Doublet Model extended by a real singlet (N2HDM) as well as
in a corresponding supersymmetric theory. Future experimental tests of
these scenarios are presented. (ii) Indirect searches for BSM physics
recently confirmed the experimental result for the anomalous magnetic
moment of the muon, leading to a 4.2 sigma discrepancy with the SM
prediction. We analyze this deviation in the Minimal Supersymmetric
Standard Model (MSSM). We show that light electroweak (EW) SUSY
particles can easily explain this discrepancy, while being in
agreement with all other experimental and theoretical constraints.
This places upper bounds on EW SUSY particles that can be tested at
current and future colliders.

Passcode: 60153342
Abstract: This work is motivated by the theory of quadratic gravity,
which is a renormalizable UV complete theory of gravity. This theory
involves higher derivatives in the action. In general for theories
with higher time derivatives, the Hamiltonian analysis of Ostrogradsky
predicts an instability. However, this Hamiltonian treatment does not
correspond to the way that these theories are treated in quantum field
theory, and the instability may be avoided in at least some cases. I
will describe a very simple model which illustrates these features. I
then go on to discuss other aspects of such higher derivative
theories, including causality and unitarity.
