This note describes a morphing method that produces signal models for fits to data in which both the event yields and kinematic distributions are simultaneously taken into account. The signal model is morphed in a continuous manner through the available multi-dimensional parameter space. [...]

Higgs cross section at N3LO+N3LL
/ Bonvini, Marco (University of Oxford (GB)) ; Marzani, Simone (University at Buffalo)
We consider the inclusive production of a Higgs boson in gluon gluon fusion and we study the impact of threshold resummation at next-to-next-to-next-to-leading logarithmic accuracy (N3LL) on the recently computed fixed-order prediction at next-to-next-to-next-to-leading order (N3LO). In order to facilitate comparisons with other studies, we focus on the rescaled large-mt effective theory (rEFT). [...]

Analytical parametrization and shape classification of anomalous HH production in EFT approach
/ Carvalho Antunes De Oliveira, Alexandra (Universita e INFN, Padova (IT)) ; Dall'Osso, Martino (Universita e INFN, Padova (IT)) ; De Castro Manzano, Pablo (Universita e INFN, Padova (IT)) ; Dorigo, Tommaso (Universita e INFN, Padova (IT)) ; Goertz, Florian (CERN) ; Gouzevitch, Maxime (Universite Claude Bernard-Lyon I (FR)) ; Tosi, Mia (CERN)
In this document we study the effect of anomalous Higgs boson couplings on non-resonant pair production of Higgs bosons (HH) at the LHC. We explore the space of the five parameters $\kappa_{\lambda}$, $\kappa_{t}$, $c_2$, $c_g$, and $c_{2g}$ in terms of the corresponding kinematics of the final state, and describe a suggested partition of the space into a limited number of regions featuring similar phenomenology in the kinematics of HH final state, along with a corresponding set of representative benchmark points. [...]

Benchmark scenarios for low $\tan\beta$ in the MSSM
The run-1 data taken at the LHC in 2011 and 2012 have led to strong constraints on the allowed parameter space of the MSSM. These are imposed by the discovery of an approximately SM-like Higgs boson with a mass of $125.09\pm0.24$~GeV and by the non-observation of SUSY particles or of additional (neutral or charged) Higgs bosons. [...]
