A double-phase argon Time Projection Chamber (TPC), with an active mass of 185 g, has been designed and constructed for the Recoil Directionality (ReD) experiment. The aim of the ReD project is to investigate the directional sensitivity of argon-based TPCs via columnar recombination to nuclear recoils in the energy range of interest (20– null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null ...
Loop Quantum Cosmology (LQC) is a theory which renders the Big Bang initial singularity into a quantum bounce, by means of short range repulsive quantum effects at the Planck scale. In this work, we are interested in reproducing the effective Friedmann equation of LQC, by considering a generic f(R,P,Q)theory of gravity, where R=g^{\mu\nu}R_{\mu\nu}is the Ricci scalar, P=R_{\mu\nu}R^{\mu\nu} and Q=R_{\alpha\beta\mu\nu}R^{\alpha\beta\mu\nu}is the Kretschmann scalar. An order reduction ...

A model that can simultaneously explain Dark Matter relic density and the apparent matter anti-matter imbalance of the universe has been recently proposed. The model requires b -hadron branching fractions to Dark Matter at the per mille level. The b -hadrons decay to a dark sector baryon, , which has a mass in the region . In this paper, we discuss the sensitivity of the LHCb experiment to search for this dark baryon, covering different types of topology and giving prospects for Runs 3 and 4 of ...

We study the masses and lifetimes of doubly charmed pentaquark primarily. The operation of masses carried out by the doubly heavy triquark-diquark model, whose results suggests the existence of stable states with the parity . The roughly calculation about lifetimes show the short magnitudes, for the parity and for . Since the pentaquark is interpreted as the stable bound states against strong decays, then we will focus on the production and possible decay channels of the pentaquark in the next s...

We present a measurement of the cosmic-ray spectrum above 100 PeV using the part of the surface detector of the Pierre Auger Observatory that has a spacing of 750~m. An inflection of the spectrum is observed, confirming the presence of the so-called \emph{second-knee} feature. The spectrum is then combined with that of the 1500 m array to produce a single measurement of the flux, linking this spectral feature with the three additional breaks at the highest energies. The combined spectrum, with a...
In this article, we study further applications of the Schwarzschild-Finsler-Randers (SFR) model which was introduced in a previous work. In this model, we investigate curvatures and the generalized Kretschmann invariant which plays a crucial role for singularities. In addition, the derived path equations are used for the gravitational redshift of the SFR-model and these are compared with the GR model. Finally, we get some results for different values of parameters of the generalized photonsphere...
