Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
A Fermionic Portal to Vector Dark Matter from a New Gauge Sector
Alexander Belyaev, Aldo Deandrea, Stefano Moretti +3
We present a new class of Dark Matter (DM) models wherein the Standard Model (SM) is extended with a new dark gauge sector. In this framework the stability of DM is provi…
Probing Dark Matter with Disappearing Tracks at the LHC
Alexander Belyaev, Stefan Prestel, Felipe Rojas-Abbate +1
Models where dark matter is a part of an electroweak multiplet feature charged particles with macroscopic lifetimes due to the charged-neutral mass split of the order of pion mass.…
Any Room Left for Technicolor? Holographic Studies of NJL Assisted Technicolour
Alexander Belyaev, Kazem Bitaghsir Fadafan, Nick Evans +1
We use a holographic description of technicolor dynamics to study gauge theories that only break chiral symmetry when aided by a strong four fermion interaction. These Nambu-Jona-L…
Any Room Left for Technicolor? Dilepton Searches at the LHC and Beyond
Alexander Belyaev, Azaria Coupe, Nick Evans +1
Precision electroweak data, a light higgs and LHC searches for new spin one particles are all very constraining on technicolor models. We use a holographic model of walking techico…
Advancing LHC Probes of Dark Matter from the Inert 2-Higgs Doublet Model with the Mono-jet Signal
A. Belyaev, T. R. Fernandez Perez Tomei, P. G. Mercadante +6
The inert 2-Higgs Doublet Model (i2HDM) is a well-motivated minimal consistent Dark Matter (DM) model, but it is rather challenging to test at the Large Hadron Collider (LHC) in th…
Problems with Higgsplosion
Alexander Belyaev, Fedor Bezrukov, Chris Shepherd +1
A recent calculation of the multi-Higgs boson production in scalar theories with spontaneous symmetry breaking has demonstrated the fast growth of the cross section with the Higgs…
Minimal Spin-one Isotriplet Dark Matter
Alexander Belyaev, Giacomo Cacciapaglia, James McKay +2
In this work we present a simple extension of the Standard Model that contains, as the only new physics component, a massive spin-one matter field in the adjoint representation of…
Interplay of the LHC and non-LHC Dark Matter searches in the Effective Field Theory approach
Alexander Belyaev, Enrico Bertuzzo, Cristian Caniu Barros +4
We present accurate and up-to-date constraints on the complete set of dimension five and six operators with scalar, fermion and vector Dark Matter (DM). We find limits using LHC mo…
Walking Technicolor in the light of searches at the LHC
Alexander Belyaev, Azaria Coupe, Mads Frandsen +2
We investigate the potential of the Large Hadron Collider (LHC) to probe one of the most compelling Beyond the Standard Model (BSM) frameworks --- Walking Technicolor (WTC), involv…
Precise test of Higgs properties via triple Higgs production in VBF at future colliders
A. S. Belyaev, P. B. Schaefers, M. C. Thomas
For certain classes of Beyond the Standard Model theories, including composite Higgs models, the coupling of the Higgs to gauge bosons can be different from the Standard Model one.…
Muon g-2 and Dark Matter suggest Non-Universal Gaugino Masses: case study at the LHC
Alexander S. Belyaev, Steve F. King, Patrick B. Schaefers
We argue that in order to account for the muon anomalous magnetic moment , dark matter and LHC data, non-universal gaugino masses at the high scale are required in the f…

The inert Two Higgs Doublet Model (i2HDM) is a theoretically well-motivated example of a minimal consistent Dark Matter(DM) model which provides mono-jet, mono-Z, mono-Higgs and Ve…
Torsion as a Dark Matter Candidate from the Higgs Portal
Alexander S. Belyaev, Ilya L. Shapiro, Marc C. Thomas
Torsion is a metric-independent component of gravitation, which may provide a more general geometry than the one taking place within general relativity. On the other hand torsion c…
