Cosmological Bounds of Sterile Neutrinos in a S U(3) C ⊗S U(3) L ⊗S U(3) R ⊗U(1) N Model as Dark Matter Candidates [PDF]

open access: yesBrazilian Journal of Physics, 2016
We study sterile neutrinos in an extension of the standard model, based on the gauge group S U(3) C ⊗S U(3) L ⊗S U(3) R ⊗U(1) N , and use this ...

Structure, Function and Diversity of the Healthy Human Microbiome

open access: yesNature, 2012
Studies of the human microbiome have revealed that even healthy individuals differ remarkably in the microbes that occupy habitats such as the gut, skin and vagina. Much of this diversity remains unexplained, although diet, environment, host genetics and

A portrait of the Higgs boson by the CMS experiment ten years after the discovery [PDF]

open access: yesNature, 2022
In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the data corresponding to the production of a 30-times larger

The Belle II Physics Book [PDF]

open access: yesProgress of Theoretical and Experimental Physics, 2018
We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB e+e- collider. Belle II collected its first collisions in 2018, and is expected to operate for the next decade.

Landesman-Lazer conditions at half-eigenvalues of the p-Laplacian [PDF]

open access: yes, 2012
We study the existence of solutions of the Dirichlet problem {gather} -\phi_p(u')' -a_+ \phi_p(u^+) + a_- \phi_p(u^-) -\lambda \phi_p(u) = f(x,u), \quad x \in (0,1), \label{pb.eq} \tag{1} u(0)=u(1)=0,\label{pb_bc.eq} \tag{2} {gather} where $p>1$, $\phi_p(
