11. B-Anomalies from flavorful U(1)' extensions, safely

Tim Höhne (TU Dortmund)

U(1)′ extensions of the standard model with generation-dependent couplings to quarks and leptons are investigated as an explanation of anomalies in rare B-decays, with an emphasis on stability and predictivity up to the Planck scale. To these ends, we introduce three generations of vector-like standard model singlet fermions, an enlarged, flavorful scalar sector, and, possibly, right-handed...

9. Constructing Effective Field Theories to Higher Mass Dimensions

Magnus Schaaf (RWTH Aachen University)

The Standard Model Effective Field Theory (SMEFT) provides a framework to parametrise the effects of yet unseen heavy degrees of freedom in a model independent way. While in recent years the interest in higher-dimensional operators has increased, the construction of a complete and minimal set of operators is remarkably challenging. In this talk, I will report on the implementation of a...

14. Dark matter phenomenology in two higgs doublet models with complex scalar singlet

Juhi Dutta (UNI/TH (Uni Hamburg, Institut fuer Theoretische Physik))

Extensions of the two higgs doublet models with a singlet scalar can easily accommodate all current experimental constraints and are highly motivated candidates for Beyond Standard Model Physics. It can successfully provide a dark matter candidate, explain baryogenesis and provide gravitational wave signals. In this work, we focus on the dark matter phenomenology of the two higgs doublet model...

10. Di-Higgs Production in Extended Higgs Sectors

Duarte Azevedo (KIT)

We study di-Higgs production in various extended Higgs sector models such as the real and complex Two-Higgs-Doublet Model, the Two-Higgs-Doublet model augmented with a real singlet field and the next-to-Minimal Sypersymmetric Standard Model. We study the di-Higgs production pp → h_i h_j, in particular the h_i = h_j = h_125 GeV scalar particle case, and we also discuss the case where h_i and/or...

13. Lepton PDFs and Multipurpose Single Lepton Searches at the LHC

Saurabh Nangia (BCTP, University of Bonn)

A final state consisting of one charged lepton, at least one jet and little missing transverse energy can be an interesting signature of new physics at the LHC that has received only limited attention so far. In this work we discuss the potential sensitivity of such a channel to various new physics scenarios. To demonstrate our point, we consider the application to $R$-parity Violating...

12. Reconciling Higgs physics and pseudo-Nambu-Goldstone dark matter in the S2HDM using a genetic algorithm

Thomas Biekoetter (T (Phenomenology))

We investigate a possible realization of pseudo-Nambu-Goldstone (pNG) dark matter in the framework of a singlet-extended 2 Higgs doublet model (S2HDM). pNG dark matter gained attraction due to the fact that direct-detection constraints can be avoided naturally because of the momentum-suppressed scattering cross sections, whereas the relic abundance of dark matter can nevertheless be accounted...

15. What pp SUSY limits mean for future e+e− colliders

Carl Mikael Berggren (FLC (FTX Fachgruppe SLB))

It is well-known that e+e− colliders have the power to with certainty exclude or discover any SUSY model that predicts a Next to lightest SUSY particle (an NLSP) that has a mass up to slightly below the half the centre-of-mass energy of the collider. Here, we present an estimation of the power of present and future hadron colliders to extend the reach of searches for SUSY, with particular...

16. Z'-explorer 2.0: unraveling the dark side

Víctor Martín Lozano (DESY)

Z'-explorer 2.0 is a free software that tests BSM theories with extra Abelian U(1) gauge bosons, Z', against current data from the LHC. The version 2.0 includes missing energy searches in particular monojet. To this end, we perform here the first public reinterpretation of the most recent ATLAS mono-jet search with 139 fb$^{-1}$. In addition, the corresponding searches in the visible final...
