A Conceptual Model for the Origin of the Cutoff Parameter in Exotic Compact Objects

W. A. Rojas C., J. R. Arenas S

A Black Hole (BH) is a spacetime region with a horizon and where geodesics converge to a singularity. At such a point, the gravitational field equations fail. As an alternative to…

Universality and thermoelectric transport properties of quantum dot systems

D. F. Aranguren-Quintero, E. Ramos, J. Silva-Valencia +3

We discuss the temperature-dependent thermoelectric transport properties of semiconductor nanostructures comprising a quantum dot coupled to quantum wires: the thermal dependence o…

Angular analysis of the $B^{+} \to K^{*+} μ^{+} μ^{-}$ decay

LHCb collaboration, R. Aaij, C. Abellán Beteta +959

We present an angular analysis of the $B^{+} \to K^{*+} (\to K_{S}^{0} π^{+}) μ^{+} μ^{-}$ decay using 9$\,\mbox{fb}^{-1}$ of $pp$ collision data collected with the L…

Measurement of CP violation in the decay $B^{+} \to K^{+} π^{0}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +960

A measurement of direct CP violation in the decay $B^{+} \to K^{+} π^{0}$ is reported using a data sample corresponding to an integrated luminosity of 5.4 $\textrm{fb}^{-1}…

The QED four -- photon amplitudes off-shell: part 1

Naser Ahmadiniaz, Cristhiam Lopez-Arcos, Misha A. Lopez-Lopez +1

The QED four-photon amplitude has been well-studied by many authors, and on-shell is treated in many textbooks. However, a calculation with all four photons off-shell is presently…

Observation of the $B_{s}^{0} \to D^{*\pm} D^{\mp}$ decay

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

A search for the $B_{s}^{0} \to D^{*\pm} D^{\mp}$ decay is performed using proton-proton collision data at centre-of-mass energies of $7$ , $8$ and $13 TeV$ collected by…
