Electroweak superpartner production at 13.6 Tev with Resummino [PDF]

open access: greenEuropean Physical Journal C: Particles and Fields, 2023
Due to the greater experimental precision expected from the currently ongoing LHC Run 3, equally accurate theoretical predictions are essential. We update the documentation of the Resummino package, a program dedicated to precision cross section ...

Exploring the flavour structure of the high-scale MSSM [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We analyse the sensitivity of quark flavour-changing observables to the MSSM, in a regime of heavy superpartners. We analyse four distinct and motivated frameworks characterising the structure of the soft-breaking terms by means of approximate flavour ...

Superpartner mass measurements with 1D decomposed MT2 [PDF]

open access: green, 2010
We propose a new model-independent technique for mass measurements in missing energy events at hadron colliders. We illustrate our method with the most challenging case of a short, single-step decay chain.

Naturally heavy superpartners and a Little Higgs [PDF]

open access: green, 2005
We construct an extension of the MSSM in which scalar superpartners can naturally be as heavy as 1 TeV. In the MSSM, the most significant fine tuning stems from the logarithmically enhanced top-stop loop contribution to the soft Higgs mass.

Fingerprints of supersymmetric spin and charge dynamics observed by inelastic neutron scattering [PDF]

open access: yesNature Communications
Supersymmetry is an algebraic property of a quantum Hamiltonian that, by giving every boson a fermionic superpartner and vice versa, may underpin physics beyond the Standard Model. Fractional bosonic and fermionic quasiparticles are familiar in condensed

A microscopic model for inflation from supersymmetry breaking [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We have proposed recently a framework for inflation driven by supersymmetry breaking with the inflaton being a superpartner of the goldstino, that avoids the main problems of supergravity inflation, allowing for: naturally small slow-roll parameters ...

Is the 125 GeV Higgs the superpartner of a neutrino? [PDF]

open access: green, 2012
Recent LHC searches have provided strong evidence for the Higgs, a boson whose gauge quantum numbers coincide with those of a SM fermion, the neutrino. This raises the mandatory question of whether Higgs and neutrino can be related by supersymmetry.

Supersymmetry Laser Arrays with High‐Order Exceptional Point

open access: yesAdvanced Photonics Research, 2023
Supersymmetry (SUSY) laser array with superpartner structure can suppress excess modes to achieve high‐intensity and high‐coherent radiation. Compared with complex superpartner, using parity time (PT) symmetry broken to manipulate SUSY laser arrays is a ...

Lepto-axiogenesis and the scale of supersymmetry

open access: yesJournal of High Energy Physics, 2023
If the Peccei-Quinn field containing the QCD axion undergoes rotations in the early universe, the dimension-five operator responsible for neutrino masses can generate a lepton asymmetry that ultimately gives rise to the observed baryon asymmetry of the ...

Noether-Wald charge in supergravity: the fermionic contribution

open access: yesJournal of High Energy Physics, 2023
We study the invariance of N $$ \mathcal{N} $$ = 1, d = 4 supergravity solutions under diffeormophisms and show that, in order to obtain consistent conditions (“Killing equations”) invariant under local supersymmetry transformations, one has to perform ...
