Derivative for Functions $f : G \to H$ , Where $G$ Is a Metric Divisible Group

Hector Andres Granada Diaz, Simeon Casanova Trujillo, Fredy E. Hoyos

In this paper, a derivative for functions $f : G \to H$ , where $G$ is any metric divisible group and $H$ is a metric Abelian group with a group metric, is defined. Basic differenti…

Some remarks on projectile motion with a linear resistance force

C. A. Morales, J. H. Muñoz, C. E. Vera

In this article we revisit the projectile motion assuming a retarding force proportional to the velocity, $F_{r} = - mk V$ . We obtain an analytical expression for the set o…

Implications of NSI constraints from ANTARES and IceCube on a simplified $Z^{'}$ model

J. M. Cabarcas, Alexander Parada, Nestor Quintero-Poveda

Recently the neutrino experiments ANTARES and IceCube have released new constraints to the non-standard neutrino interaction (NSI) parameter $ε_{μτ}^{d}$ (flavor off-diagonal). These…

Singlet vector leptoquark model facing recent LHCb and BABAR measurements

Cristian H. García-Duque, J. M. Cabarcas, J. H. Muñoz +2

Very recently the LHCb experiment released the first measurement of the ratio $R (Λ_{c}) = BR (Λ_{b} \to Λ_{c} τ ν ˉ_{τ}) / BR (Λ_{b} \to Λ_{c} μ ν ˉ_{μ})$ . Moreover, the BABAR experiment…

Extra gauge bosons and lepton flavor universality violation in $Υ$ and $B$ meson decays

Cristian H. García-Duque, J. H. Muñoz, Néstor Quintero +1

Lepton flavor universality can be tested through the ratio of semileptonic $B$ meson decays and leptonic $Υ$ meson decays, with $Υ \equiv Υ (n S)$ ( $n = 1, 2, 3$ ). For the charged-current…

Tests of the Atomki anomaly in lepton pair decays of heavy mesons

G. López Castro, Néstor Quintero

The anomalies recently reported in lepton pair transitions of $^{8}$ Be $^{*}$ and $^{4}$ He nuclei may be attributed to the existence of a feebly interacting light vector boson $X 17$ . We s…
