Beyond scalar QED radiative corrections: The ρ ± − ρ 0 width difference, final state radiation corrections, and their impact on Δ a μ HVP , LO [ τ ]
In a previous paper [Flores-Baez , ] we have calculated the radiative corrections to ρ → π π decays, aiming to estimate the width difference between charged and neutral rho mesons. There, we have used the scalar quantum electrodynamics approximation and considered the convection terms to keep the loop contributions finite in the case of charged rho meson decays. Here we compute the radiative corrections by considering the electromagnetic structure of charged mesons and we also include the full Lorentz structure of the electromagnetic vertices. We reevaluate the width difference of ρ ± − ρ 0 vector mesons and calculate the structure-dependent contributions to final state radiation terms in the e + e − → π + π − cross section. Both effects are important inputs for evaluating the isospin breaking corrections in the dominant hadronic vacuum polarization contributions to the muon g − 2 when using τ lepton data.

Study of the ρ0 Decay into π0π0γ Within Framework of Chiral Perturbation Theory with Resonances
In this work, we calculate the Branching Ratio (BR) of the process at tree level within the theoretical framework of with resonances, including the odd intrinsic parity sector. Owing to the nature of an effective field theory, the BR depends on three unknown couplings of the model: and the combination . To constrain these unknown couplings, we use the experimental BR of this decay and explore the possibility of reducing the number of unknown couplings through the on-shell condition at one vertex. Our result suggests that off-shell conditions must be applied to both vertices, leading to a space parameter for the pair ().Open AccessStudy of the ρ0 Decay into π0π0γ Within Framework of Chiral Perturbation Theory with Resonances

Study of the ρ0 Decay into π0π0γ Within Framework of Chiral Perturbation Theory with Resonances
In this work, we calculate the branching ratio (BR) of the decay process ρ0→π0π0γ within the theoretical framework of chiral perturbation theory with resonances, employing the odd intrinsic parity lagrangian. Our analysis shows that the BR depends solely on the LECs c57≡c5+c7, and d4. Since the experimentally measured BR does not provide sufficient constraints, the number of free parameters is reduced by applying on-shell and off-shell conditions at the interaction vertices. Our result shows that using full on-shell conditions is not consistent with the experimental BR. Therefore, we present an allowed region (contour plot) for (c57,d4) that is compatible with the experimental BR. We emphasize that once the differential BR becomes accessible, a fitting procedure can be carried out to delineate the parameter space.

Chiral symmetry restoration and the critical end point in QCD
In a system of quark matter we study the chiral phase transition, the behavior of the chiral and quark number susceptibility and the CEP at finite temperature and chemical potential. This is done within the framework of two-flavor Nambu and Jona-Lasinio model. We have calculated the chiral quark condensate and the quark number density and, with this, we have found the phase transition type. With these quantities we have determined the phase diagram for QCD and the CEP.

Muon g-2 through a flavor structure on soft SUSY terms
In this work we analyze the possibility to explain the muon anomalous magnetic moment discrepancy within theory and experiment through lepton flavor violation processes. We propose a flavor extended MSSM by considering a hierarchical family structure for the trilinear scalar Soft-Supersymmetric terms of the Lagranagian, present at the SUSY breaking scale. We obtain analytical results for the rotation mass matrix, with the consequence of having non-universal slepton masses and the possibility of leptonic flavour mixing. The one-loop supersymmetric contributions to the leptonic flavour violating process $\tau \to \mu\gamma$ are calculated in the physical basis, with slepton flavour mixed states, instead of using the well known Mass Insertion Method. We present the regions in parameter space where the muon g-2 problem is either entirely solved or partially reduced through the contribution of these flavor violating processes.Open AccessMuon g-2 through a flavor structure on soft SUSY terms

Lepton flavor violation in an extended MSSM
In this work we explore a lepton flavor violation effect induced at one loop for a flavor structure in an extended minimal standard supersymmetric model, considering an ansatz for the trilinear term. In particular we find a finite expression which will show the impact of this phenomena in the h → μτ decay, produced by a mixing in the trilinear coupling of the soft supersymmetric Lagrangian.
