Extended Gauge Mediation in the NMSSM with Displaced LHC Signals / Badziak, Marcin (Warsaw U.) ; Desai, Nishita (U. Montpellier 2, LUPM) ; Hugonie, Cyril (U. Montpellier 2, LUPM) ; Ziegler, Robert (CERN)
We analyze models of extended Gauge Mediation in the context of the NMSSM, concentrating on supersymmetric spectra with light gluinos, low fine-tuning and decays of the lightest neutralino leading to displaced vertices. While the minimal scenario has rather heavy gluinos as a result of restrictions from the Higgs sector, we propose two new models in which the gluino can be as light as allowed by direct searches at the LHC, with a mass of about 1.7 TeV and 2.0 TeV, respectively. [...]

Accidentally light scalars from large representations / Brümmer, Felix (U. Montpellier 2, LUPM) ; Ferrante, Giacomo (U. Montpellier 2, LUPM) ; Frigerio, Michele (U. Montpellier, L2C) ; Hambye, Thomas (Brussels U. ; CERN)
In models with spontaneous symmetry breaking by scalar fields in large group representations, we observe that some of the scalar masses can be loop-suppressed with respect to the naive expectation from symmetry selection rules. We present minimal models -- the $\rm{SU(2)}$ five-plet and $\rm{SU(3)}$ ten-plet -- with such accidentally light scalars, featuring compact tree-level flat directions lifted by radiative corrections.

Multiple D3-instantons and mock modular forms I / Alexandrov, Sergei (U. Montpellier, L2C) ; Banerjee, Sibasish (IPhT, Saclay) ; Manschot, Jan (Trinity Coll., Dublin) ; Pioline, Boris (CERN ; Paris, LPTHE)
We study D3-instanton corrections to the hypermultiplet moduli space in type IIB string theory compactified on a Calabi-Yau threefold. In a previous work, consistency of D3-instantons with S-duality was established at first order in the instanton expansion, using the modular properties of the M5-brane elliptic genus. [...]

A new implementation of the NMSSM Higgs boson decays / Baglio, J (Karlsruhe U., ITP) ; Dao, T.N (Karlsruhe U., ITP) ; Gröber, R (Karlsruhe U., ITP) ; Mühlleitner, M.M (Karlsruhe U., ITP) ; Rzehak, H (CERN ; Freiburg U.) ; Spira, M (PSI, Villigen) ; Streicher, J (Karlsruhe U., ITP) ; Walz, K (Karlsruhe U., ITP)
Supersymmetric theories provide elegant extensions of the Standard Model. Among these the NMSSM is a model which in addition to the content of the MSSM includes a new singlet to solve the mu problem. [...]

Sfermion decays into singlets and singlinos in the NMSSM / Kraml, S. (CERN) ; Porod, W. (Valencia U., IFIC ; Zurich U.)
We investigate how the addition of the singlet Higgs field in the NMSSM changes the sfermion branching ratios as compared to the MSSM. We concentrate in particular on the third generation, discussing decays of the heavier stop, sbottom or stau into the lighter mass eigenstate plus a scalar or pseudoscalar singlet Higgs. [...]

A search for light Higgs bosons from supersymmetric cascade decays in proton-proton collisions at 13 TeV /CMS Collaboration
A search for pairs of boosted light Higgs bosons ($\mathrm{H}_1$) produced in supersymmetric cascade decays is performed in final states with small missing transverse momentum. The complete LHC Run II proton-proton collision data set is used, recorded with the CMS detector at a centre-of-mass energy of $13~\mathrm{TeV}$ and corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$.
