Deviations to cobimaximal mixing in a 3+1 neutrino scenario

Diana C. Rivera-Agudelo, S. L. Tostado

Cobimaximal mixing remains a viable approximate pattern since the predicted atmospheric angle ( $π /4$ ) and Dirac CP phase ( $- π /2$ ) are compatible with current experimental data at t…

Approximate magic symmetry in a cobimaximal scenario of Majorana neutrinos

Diana C. Rivera-Agudelo, S. L. Tostado, Nelson E. Valderrama-Florez

The searches for an underlying pattern in neutrino masses have motivated different proposals for textures in the neutrino mass matrix, which is also related to particular arrangeme…

Deviations to $μ - τ$ symmetry in a cobimaximal scenario

Diana C. Rivera-Agudelo, S. L. Tostado

Within the different patterns of the neutrino mixing matrix, the cobimaximal mixing remains a plausible possibility for understanding the flavor structure of neutrinos as it is con…

Human Trafficking in Mexico: Data sources, Network Analysis and the Limits of Dismantling Strategies

Sofía de la Mora Tostado, Mayra Núñez-López, Esteban A. Hernández-Vargas

Human trafficking is a heartless crime that represents the second most profitable crime in the world. Mexico's geographical position makes it a country with high levels of human tr…

Restricting Majorana phases in the Tri-Bi-Maximal limit

Diana C. Rivera-Agudelo, S. L. Tostado

The Tri-Bi-Maximal pattern has been long investigated as the symmetric scenario that lies behind the neutrino mixing matrix. It predicts a null reactor angle and hence forbids $C P$ …

Deviations to Tri-Bi-Maximal mixing in the limit of $μ - τ$ symmetry

Diana C. Rivera-Agudelo, S. L. Tostado, Abdel Pérez-Lorenzana

In the limit of an approximate $μ - τ$ symmetry in the neutrino mass matrix, we explore deviations to the Tri-Bi-Maximal mixing pattern in the neutrino sector. We consider two differ…

Evaluation of CKM matrix elements from exclusive $P_{ℓ 4}$ decays

C. S. Kim, G. López Castro, S. L. Tostado

We consider the exclusive $P_{ℓ 4}$ decays, $P \to (P_{1} P_{2})_{V} ℓ ν_{ℓ}$ , where the subindex $V$ means that the invariant mass of the pseudoscalar pair is taken within a small…

Remarks on the Standard Model predictions for $R (D)$ and $R (D^{*})$

C. S. Kim, G. Lopez-Castro, S. L. Tostado +1

Semileptonic $b \to c$ transitions, and in particular the ratios $R (D^{(*)}) = \frac{Γ ( B \to D ^{(*)} τ ν )}{Γ ( B \to D ^{(*)} ℓ ν )}$ , can be used to test the univers…

A new long distance contribution to $B^{\pm} \to K^{\pm} / π^{\pm} ℓ^{+} ℓ -$ decays

A. Guevara, G. López Castro, P. Roig +1

We have identified a missing long-distance (one-photon exchange) contribution to the $B^{\pm} \to K^{\pm} / π^{\pm} ℓ^{+} ℓ^{-}$ decays. Although it does not help to explain the anomaly mea…

Long-distance weak annihilation contribution to the $B^{\pm} \to (π^{\pm}, K^{\pm}) ℓ^{+} ℓ^{-}$ decays

A. Guevara, G. López Castro, P. Roig +1

We propose an alternative evaluation of the long-distance weak annihilation (WA, also called one-photon exchange in this paper) contribution to the rare semileptonic $B^{\pm}\to (π…
