Massive gravitino scattering amplitudes and the unitarity cutoff of the new Fayet-Iliopoulos terms

Autor: Ignatios Antoniadis, Anthony Guillen, François Rondeau

Publikováno v: Journal of High Energy Physics

We compute the $2\rightarrow 2$ gravitino scattering amplitudes at tree level in supergravity theories where supersymmetry is spontaneously broken. In the unitary gauge, the gravitino becomes massive (of mass $m_{3/2}$) by absorbing the Goldstino, an

Light Sgoldstinos and Higgs Sector in the Supersymmetric Extension of the Standard Model

Autor: E. A. Kriukova

Publikováno v: Bulletin of the Lebedev Physics Institute. 48:41-45

The phenomenology of the simplest processes involving sgoldstino 260–1000 GeV in mass is studied. The effect of the sgoldstino–Higgs mixing on sgoldstino branching ratio and the cross-section of its production in proton–proton collisions is con

We discuss the possibility that inflation is driven by supersymmetry breaking with the superpartner of the goldstino (sgoldstino) playing the role of the inflaton. Imposing an R-symmetry allows to satisfy easily the slow-roll conditions, avoiding the

The light sgoldstino phenomenology: explanations for the muon (g − 2) deviation and KOTO anomaly

Autor: Ying Li, Tianjun Li, Bin Zhu, Xuewen Liu

Publikováno v: Journal of High Energy Physics
Journal of High Energy Physics, Vol 2020, Iss 10, Pp 1-18 (2020)

In this work, we study the long-standing experimental anomaly in muon $(g-2)$ and also recent anomalous excess in $K_L\to \pi^0+\nu\bar\nu$ at the J-PARC KOTO experiment with sgoldstino. After supersymmetry breaking, the interactions between quarks a

Sgoldstino signature in hh, W + W − and ZZ spectra at the LHC

Journal of High Energy Physics, Vol 2020, Iss 5, Pp 1-26 (2020)

In a supersymmetric extension of the Standard Model of particle physics (SM) with low scale of supersymmetry breaking, sgoldstino of (sub)TeV mass can be observed at the Large Hadron Collider (LHC) as a peak in diboson mass spectra. Moreover, as a si

Simple sinflaton-less α-attractors

Autor: Yusuke Yamada, Renata Kallosh

Publikováno v: Journal of High Energy Physics, Vol 2019, Iss 3, Pp 1-12 (2019)
Journal of High Energy Physics

We construct the simplest inflationary α-attractor models in supergravity: it has only one scalar, the inflaton. There is no sinflaton since the inflaton belongs to an orthogonal nilpotent superfield where the sinflaton depends on fermion bilinears.
