Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +368

Dark matter particles could be superheavy, provided their lifetime is much longer than the age of the universe. Using the sensitivity of the Pierre Auger Observatory to ultra-high…

The interplay between the electromagnetic and the muonic longitudinal profile at production

Ruben Conceição, Sofia Andringa, Lorenzo Cazon +1

The electromagnetic and the muonic longitudinal profile at production enclosure important information about the primary particle and the hadronic interactions that rule the shower…

Sensitivity to primary composition and hadronic models from average shape of high energy cosmic ray shower profiles

Sofia Andringa, Ruben Conceição, Francisco Diogo +1

The concept of Universal Shower Profile is used to characterize the average behavior of high energy cosmic rays. The shape variables contain important information about composition…

The muonic longitudinal shower profiles at production

S. Andringa, L. Cazon, R. Conceição +1

In this paper the longitudinal profile of muon production along the shower axis is studied. The characteristics of this distribution is investigated for different primary masses, z…

Multiplicity Fluctuations in One- and Two-Dimensional Angular Intervals Compared with Analytic QCD Calculations

B. Buschbeck, F. Mandl

Multiplicity fluctuations in rings around the jet axis and in off-axis cones have been measured by the DELPHI collaboration in annihilations into hadrons at LEP energies.…

Vector Boson decays of the Higgs Boson

J. C. Romao, S. Andringa

We derive the width of the Higgs boson into vector bosons. General formulas are derived both for the on-shell decay H -> VV as well for the off-shell decays, H -> V^* V and H -> V^…
