Is the Standard Model Effective Field Theory Enough for Higgs Pair Production?
Íñigo Asiáin, Ramona Gröber, Lorenzo Tiberi
We study Higgs-boson pair production in the Standard Model Effective Field Theory (SMEFT) up to dimension six and in the Higgs Effective Field Theory (HEFT) at leading order in the…
Standard Model and SMEFT Higgs theory overview
Ramona Gröber
After more than a decade from its discovery, the Higgs boson remains at the centre of the particle physics programme. While its couplings to vector bosons and third-generation ferm…
: updated predictions at NLO QCD
Benjamin Campillo Aveleira, Long Chen, Joshua Davies +9
We present state-of-the-art predictions for the inclusive cross section of gluon-initiated production, following the recommendations of the LHC Higgs Working Group. In particu…
Two loops, four tops and two schemes: a renormalization story
Stefano Di Noi, Ramona Gröber
We calculate the four-top quark operator contributions to the two-loop renormalization constants of the fermion and gluon fields, necessary to obtain the renormalization group equa…
Subleading operators and gamma5-scheme dependence in SMEFT for Higgs boson pair production
Stefano Di Noi, Ramona Gröber, Gudrun Heinrich +3
The calculation of contributions from the chromomagnetic and four-top-quark-operators within Standard Model Effective Field Theory (SMEFT) to Higgs boson pair production in gluon f…
On schemes and the interplay of SMEFT operators in the Higgs-gluon coupling
Stefano Di Noi, Ramona Gröber, Gudrun Heinrich +2
We calculate the four-top quark operator contributions to Higgs production via gluon fusion in the Standard Model Effective Field Theory. The four-top operators enter for the first…
Padé approach to top-quark mass effects in gluon fusion amplitudes
Joshua Davies, Ramona Gröber, Andreas Maier +2
Gluon fusion processes like single and double Higgs production exhibit slow convergence and pose severe computational challenges. We show how the top-quark mass dependence of the v…
Probing light Yukawa couplings in Higgs pair production
Lina Alasfar, Ramona Gröber
One of the puzzles of the SM is the large hierarchy between the Yukawa couplings of different flavours. Yukawa couplings of the first and the second generation are constrained only…
Higgs boson potential at colliders: status and perspectives
B. Di Micco, M. Gouzevitch, J. Mazzitelli +104
This document summarises the current theoretical and experimental status of the di-Higgs boson production searches, and of the direct and indirect constraints on the Higgs boson se…
Les Houches 2017: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, M. Dolan, S. Gori +80
We present the activities of the `New Physics' working group for the `Physics at TeV Colliders' workshop (Les Houches, France, 5--23 June, 2017). Our report includes new physics st…
Higgs-Boson Masses and Mixing Matrices in the NMSSM: Analysis of On-Shell Calculations
Peter Drechsel, Ramona Gröber, Sven Heinemeyer +3
We analyze the Higgs-boson masses and mixing matrices in the NMSSM based on an on-shell (OS) renormalization of the gauge-boson and Higgs-boson masses and the parameters of the top…
Pair Production of Beyond the Standard Model Higgs Bosons
Ramona Gröber
Higgs pair production is not only sensitive to the trilinear Higgs self-coupling, but it can give access to other anomolous couplings, as e.g. a novel coupling. In Com…
NLO QCD Corrections to Higgs Pair Production including Dimension-6 Operators
Ramona Grober, Margarete Muhlleitner, Michael Spira +1
New Physics that becomes relevant at some high scale beyond the experimental reach, can be described in the effective theory approach by adding higher-dimensional operators to…
Light Stop Decays: Implications for LHC Searches
R. Grober, M. Muhlleitner, E. Popenda +1
We investigate the flavour-changing neutral current decay of the lightest stop into a charm quark and the lightest neutralino and its four-body decay into the lightest neutralino,…
Composite Higgs Boson Pair Production at the LHC
Ramona Grober, Margarete Muhlleitner
The measurement of the trilinear and quartic Higgs self-couplings is necessary for the reconstruction of the Higgs potential. This way the Higgs mechanism as the origin of electrow…
