We present the new version v2.0 of the public code BlackHawk designed to compute the Hawking radiation of black holes, with both primary and hadronized spectra. This new version aims at opening an avenue toward physics beyond the Standard Model (BSM)

We investigate the asymptotic structure of the free Rarita-Schwinger theory in four spacetime dimensions at spatial infinity in the Hamiltonian formalism. We impose boundary conditions for the spin-3/2 field that are invariant under an infinite-dimen

Numerical study of the spin-3/2 Ashkin-Teller model

Autor: R. Boudefla, S. Bekhechi, F.Hontinfinde

Publikováno v: Condensed Matter Physics, Vol 18, Iss 3, p 33703 (2015)

The study of the Ashkin-Teller model (ATM) of spin-3/2 on a hypercubic lattice is undertaken via Monte Carlo (MC) simulation. The phase diagrams are displayed and discussed in the physical parameter space. Rich physical properties are recovered, name

Punctures and p-spin curves from matrix models II

Autor: Edouard Brézin, Shinobu Hikami

Publikováno v: J.Statist.Phys.
J.Statist.Phys., 2021, 183 (3), pp.36. ⟨10.1007/s10955-021-02776-4⟩

We report here an extension of a previous work in which we have shown that matrix models provide a tool to compute the intersection numbers of p-spin curves. We discuss further an extension to half-integer p, and in more details for p=1/2 and p=3/2.

We point out the peculiar form of the gravitational wave signal expected from a gas of particles carry spin 3/2 produced during preheating. Given the very few ways that gravitinos can manifest themselves in an experimentally observable way, we stress

Stochastic gravitational waves can be produced during the preheating when out-of-equilibrium particles are produced with an anisotropic stress tensor. We discuss the case where these particles carry spin 3/2. We compute the spectrum of the gravitatio
