Problems with Higgsplosion
/ Belyaev, Alexander ; Bezrukov, Fedor ; Shepherd, Chris ; Ross, Douglas
A recent calculation of the multiHiggs boson production in scalar theories with spontaneous symmetry breaking has demonstrated the fast growth of the cross section with the Higgs multiplicity at sufficiently large energies, called “Higgsplosion.” It was argued that Higgsplosion solves the Higgs hierarchy and finetuning problems.

LHC dark matter signals from vector resonances and top partners
/ Belyaev, Alexander S. ; Flacke, Thomas ; Jain, Bithika ; Schaefers, Patrick B.
Extensions of the standard model which address the hierarchy problem and dark matter (DM) often contain top partners and additional resonances at the TeV scale. [...]

Muon $g2$ and dark matter suggest nonuniversal gaugino masses: $SU\left(5\right)\times {A}_{4}$ case study at the LHC
/ Belyaev, Alexander S. ; King, Steve F. ; Schaefers, Patrick B.
We argue that in order to account for the muon anomalous magnetic moment $g2$, dark matter and LHC data, nonuniversal gaugino masses ${M}_{i}$ at the high scale are required in the framework of the minimal supersymmetric standard model. [...]

Anatomy of the inert twoHiggsdoublet model in the light of the LHC and nonLHC dark matter searches
/ Belyaev, Alexander ; Cacciapaglia, Giacomo ; Ivanov, Igor P. ; RojasAbatte, Felipe ; et al
The inert twoHiggsdoublet model (i2HDM) is a theoretically wellmotivated example of a minimal consistent dark matter (DM) model which provides monojet, mono$Z$, monoHiggs, and vectorboson$\mathrm{fusion}+{E}_{T}^{\mathrm{miss}}$ signatures at the LHC, complemented by signals in direct and indirect DM search experiments.

Dark Matter characterization at the LHC in the Effective Field Theory approach
/ Belyaev, Alexander ; Panizzi, Luca ; Pukhov, Alexander ; Thomas, Marc
We have studied the complete set of dimension 5 and dimension 6 effective operators involving the interaction of scalar, fermion and vector Dark Matter (DM) with SM quarks and gluons, to explore the possibility to distinguish these operators and characterise the spin of DM at the LHC. [...]

Diboson signatures as standard candles for partial compositeness
/ Belyaev, Alexander ; Cacciapaglia, Giacomo ; Cai, Haiying ; Ferretti, Gabriele ; et al
Composite Higgs Models are often constructed including fermionic top partners with a mass around the TeV scale, with the top partners playing the role of stabilizing the Higgs potential and enforcing partial compositeness for the top quark. [...]

A to Z of the muon anomalous magnetic moment in the MSSM with PatiSalam at the GUT scale
/ Belyaev, Alexander ; CamargoMolina, José ; King, Steve ; Miller, David ; et al
We analyse the low energy predictions of the minimal supersymmetric standard model (MSSM) arising from a GUT scale PatiSalam gauge group further constrained by an A 4 × Z 5 family symmetry, resulting in four soft scalar masses at the GUT scale: one lefthanded soft mass m 0 and three righthanded soft masses m 1 , m 2 , m 3 , one for each generation.

Hunting for neutral, longlived exotica at the LHC using a missing transverse energy signature
/ Belyaev, Alexander ; Moretti, Stefano ; Nickel, Kilian ; Thomas, Marc ; et al
Searches at the Large Hadron Collider (LHC) for neutral, longlived particles have historically relied on the detection of displaced particles produced by their decay within the detector volume. [...]

Forwardbackward asymmetry as a discovery tool for Z′ bosons at the LHC
/ Accomando, Elena ; Belyaev, Alexander ; Fiaschi, Juri ; Mimasu, Ken ; et al
The ForwardBackward Asymmetry (AFB) in Z ′ physics is commonly only perceived as the observable which possibly allows one to interpret a Z ′ signal appearing in the DrellYan channel by distinguishing different models of such (heavy) spin1 bosons. [...]
