JetVHeto is a user-friendly, fast program to perform NNLL resummation for jet-veto efficiencies and cross sections in Higgs and Z-boson production, as well as resummation in the leading logarithms of the jet radius. It also performs NNLL resummation for the Higgs and Z-boson transverse momentum. The resummed predictions can be matched to fixed-order results provided by the user up N3LO.

Rosetta is a framework for translation between different bases of Standard Model (SM) Effective Field Theory (EFT) operators. It implements translations between a number of popular operator bases such as the so called Warsaw, SILH and Higgs (a.k.a BSM primaries) bases via a simple SLHA style input/output format. As such, it can readily be interfaced with existing HEP tools such as Monte Carlo event generators. In order to make this possible, Rosetta also contains a basis implementation called the 'BSM Characterisation Lagrangian' or 'bsmc' whose output SLHA card is designed to be compatible with a purpose-made FeynRules implementation that can be found at:

Another key feature of Rosetta is to allow users to easily define their own input bases such that implementing a translation to any one of the core bases gives access to translations to all existing bases for which a translation is possible. This may be useful if a certain HEP tool for SM EFT assumes the use of a particular basis. In this case, Rosetta would give access to the tool to users working in other bases and potentially widen its user base. Rosetta also comes with an example of this in its eHDECAY interface which assumes the SILH basis as input for calculating the effect of EFT operators to the Higgs width and branching fractions.

The full documentation of the program can be found in arXiv:1508.05895
