 Ring Relations and Mirror Map from Branes / Assel, Benjamin (CERN) We study the space of vacua of three-dimensional $\mathcal{N}=4$ theories from a novel approach building on the type IIB brane realization of the theory and in which the insertion of local chiral operators in the path integral is obtained from integrating out light modes in appropriate brane setups.

 Simplified dark matter models with two Higgs doublets: I. Pseudoscalar mediators / Bauer, Martin (U. Heidelberg, ITP) ; Haisch, Ulrich (Oxford U., Theor. Phys. ; CERN) ; Kahlhoefer, Felix (DESY) We study a new class of renormalisable simplified models for dark matter searches at the LHC that are based on two Higgs doublet models with an additional pseudoscalar mediator.

 On exponential suppression of the cosmological constant in non-SUSY strings at two loops and beyond / Abel, Steven (Durham U., IPPP) ; Stewart, Richard J. (CERN) Two independent criteria are presented that together guarantee exponential suppression of the two-loop cosmological constant in non-supersymmetric heterotic strings.

 Rescattering effects in the hadronic-light-by-light contribution to the anomalous magnetic moment of the muon / Colangelo, Gilberto (Bern U.) ; Hoferichter, Martin (Washington U., Seattle ; Santa Barbara, KITP) ; Procura, Massimiliano (CERN) ; Stoffer, Peter (Bonn U., HISKP ; UC, San Diego) We present a first model-independent calculation of $\pi\pi$ intermediate states in the hadronic-light-by-light (HLbL) contribution to the anomalous magnetic moment of the muon $(g-2)_\mu$ that goes beyond the scalar QED pion loop.

 A Simple Method to detect spontaneous CP Violation in multi-Higgs models / Ogreid, O.M. (Bergen Coll. Higher Educ.) ; Osland, P. (Bergen U.) ; Rebelo, M.N. (Lisbon, CFTP ; CERN) For models with several Higgs doublets we present an alternative method to the one proposed by Branco, Gerard and Grimus, in 1984, to check whether or not CP is spontaneously violated in the Higgs potential.

 Dimension-6 Operator Analysis of the CLIC Sensitivity to New Physics / Ellis, John (King's Coll. London ; CERN) ; Roloff, Philipp (CERN) ; Sanz, Veronica (Sussex U.) ; You, Tevong (Cambridge U.) We estimate the possible accuracies of measurements at the proposed CLIC $e^+e^-$ collider of Higgs and $W^+W^-$ production at centre-of-mass energies up to 3TeV, incorporating also Higgsstrahlung projections at higher energies that had not been considered previously, and use them to explore the prospective CLIC sensitivities to decoupled new physics.

 Supersymmetric partition functions and the three-dimensional A-twist / Closset, Cyril (CERN) ; Kim, Heeyeon (Perimeter Inst. Theor. Phys.) ; Willett, Brian (Santa Barbara, KITP) We study three-dimensional $\mathcal{N}=2$ supersymmetric gauge theories on $\mathcal{M}_{g,p}$, an oriented circle bundle of degree $p$ over a closed Riemann surface, $\Sigma_g$.

 The $\Lambda$-parameter in 3-flavour QCD and $\alpha_s(m_Z)$ by the ALPHA collaboration / Bruno, M. (Brookhaven) ; Dalla Brida, M. (INFN, Milan Bicocca ; NIC, Zeuthen) ; Fritzsch, P. (CERN ; Madrid, IFT) ; Korzec, T. (Bergische U., Wuppertal (main)) ; Ramos, A. (CERN) ; Schaefer, S. (NIC, Zeuthen) ; Simma, H. (NIC, Zeuthen) ; Sint, S. (Trinity Coll., Dublin) ; Sommer, R. (NIC, Zeuthen ; Humboldt U., Berlin) We present results by the ALPHA collaboration for the $\Lambda$-parameter in 3-flavour QCD and the strong coupling constant at the electroweak scale, $\alpha_s(m_Z)$, in terms of hadronic quantities computed on the CLS gauge configurations. The first part of this proceedings contribution contains a review of published material \cite{Brida:2016flw,DallaBrida:2016kgh} and yields the $\Lambda$-parameter in units of a low energy scale, $1/L_{\rm had}$.
