Exact theory of freeze-out
Cannoni, Mirco
(SpringerOpen, 2015-03)
We show that the standard theory of thermal production and chemical decoupling of WIMPs is incomplete. The hypothesis that WIMPs are produced and decouple from a thermal bath implies that the rate equation the bath ... -
Formalism and upper limits for spin-dependent cross sections in dark matter elastic scattering with nuclei
Cannoni, Mirco (American Physical Society, 2011)
We revise the spin-dependent neutralino-nucleus elastic scattering comparing the formalisms and approximations found in literature for the momentum transfer dependent structure functions. We argue that one of the normalized ... -
New gamma ray signal from gravitationally boosted neutralinos at the galactic center
Cannoni, Mirco; Gómez Santamaría, Mario Emilio; Pérez García, M. A.; Vergados, J. D. (American Physical Society, 2012)
We discuss the possibility that colliding dark matter particles in the form of neutralinos may be gravitationally boosted near the supermassive black hole at the Galactic center so that they can have enough collision energy ... -
Probing dark matter and constrained MSSM with same-sign dilepton searches at the LHC
Cannoni, Mirco; Panella, O.; Pioppi, M.; Santoni, M. (American Physical Society, 2012)
We introduce new observables for the study of the inclusive same-sign dilepton production at the LHC which are built out of ratios of the observed number of same-sign dileptons, both with same Nd (l, l) and different flavor ... -
Relativistic and nonrelativistic annihilation of dark matter: a sanity check using an effective field theory approach
Cannoni, Mirco (SpringerOpen, 2016-03)
We find an exact formula for the thermally averaged cross section times the relative velocity σvrel with relativistic Maxwell–Boltzmann statistics. The formula is valid in the effective field theory approach when the ... -
Relativistic ⟨ σ v rel ⟩ in the calculation of relics abundances : a closer look
Cannoni, Mirco (American Physical Society, 2014)
In this paper we clarify the relation between the invariant relativistic relative velocity Vr, the Møller velocity ¯v, and the nonrelativistic relative velocity vr. Adopting Vr as the true physical relative velocity for ... -
Scheme for the extraction of WIMP-nucleon scattering cross sections from total event rates
Cannoni, Mirco; Vergados, J. D.; Gómez Santamaría, Mario Emilio (American Physical Society, 2011)
We propose a scheme that allows to analytically determine the three elementary cross sections and connect the solutions to the relative sign between the proton and the neutron spin scattering amplitudes once the measurements ... -
Supersymmetric Lepton Flavour Violation and Neutrinos mass textures : an update
Gómez Santamaría, Mario Emilio; Cannoni, Mirco (IOP Publishing:, 2013)
We revise the prospects for the observation of charged lepton avour violation (LFV), in the light of the recent results from the LHC, MEG and neutrino experiments. We work in the context of the Minimal Supersymmetric ... -
Supersymmetry searches in GUT models with non-universal scalar masses
Cannoni, Mirco; Ellis, J.; Gómez Santamaría, Mario Emilio; Lola, S.; Ruiz de Austri, R. (IOP Publishing, 2016)
We study SO(10), SU(5) and flipped SU(5) GUT models with non-universal soft supersymmetry-breaking scalar masses, exploring how they are constrained by LHC supersymmetry searches and cold dark matter experiments, and how ...
