A bstractWe present standard model (SM) estimates for exclusive c → uγ processes in heavy quark and hybrid frameworks. Measured branching ratios ℬD0→ϕK¯∗0γ$$ \mathrm{\mathcal{B}}\left({D}^0\to\ \left(\phi, {\overline{K}}^{\ast 0}\right)\gamma \right) $$ are at or somewhat exceeding the upper range of the SM and suggest slow convergence of the 1/mD, αs-expansion. Model-independent constraints on |ΔC| = | ΔU | = 1 dipole operators from ℬ(D0 → ρ0γ) data are obtained. Predictions and implications… 
Charm CP: $\Delta A_{CP}$ and Radiative decays
Motivated by the very important discovery of CP violation in charm-decays for the first time, by the LHCb collaboration, the role of nearby resonances such as the scalar $f_0(1710)$ in accounting for
Probing QCD dynamics and the standard model with $$ {D}_{(s)}^{+}\to {P}_1^{+}{P}_2^0\gamma $$ decays
We compute 10 radiative three-body decays of charged charmed mesons D → PP γ and Ds → PP γ, P = π,K, in leading order QCDF, HHχPT and the soft photon approximation. We work out decay distributions
Probing the standard model with rare charm decays
This thesis comprises a study of rare charm decays in the standard model (SM) and beyond. Within an effective theory framework, we calculate the SM Wilson coefficients to (partly) next-to-next-to
Rare B, D and K decays, radiative and electroweak penguin decays, including constraints on $V_{td}/V_{ts}$ and $\epsilon'/\epsilon$: Summary of CKM 2018 working group 3.
Rare $B$, $D$ and $K$ decays provide interesting probes of the Standard Model (SM), with a potential sensitivity to New Physics (NP) higher than other, more common, decays. Their experimental
The photon polarization in radiative D decays, phenomenologically
We work out the phenomenology of untagged time-dependent analysis with radiative $$D^0$$D0-decays into CP eigenstates, which allows to probe the photon polarization by means of the charm mesons’
Resonance enhancement of Charm CP.
It is suggested that a nearby $0^{++}$ resonance, $f_0$(1710) of mass $m_f=1723 MeV$ and width $\Gamma=139$ MeV is playing a significant role in efficiently providing the strong (CP-conserving) and
Rare radiative charm decays in the standard model and beyond
Motivated by the recent measurement of $D^0\to\rho^0\gamma$ improved standard model (SM) predictions for branching ratios and CP asymmetries of radiative charm decay are given. Weak annihilation
Fe b 20 20 The D → ρ semileptonic and radiative decays within the light-cone sum rules
The measured branching ratio of the D meson semileptonic decay D → ρeνe, which is based on the 0.82 fb CLEO data taken at the peak of ψ(3770) resonance, disagrees with the traditional SVZ sum rules
Null tests from angular distributions in D→P1P2l+l− , l=e , μ decays on and off peak
We systematically analyze the full angular distribution in $D \to P_1 P_2 l^+ l^-$ decays, where $P_{1,2}=\pi,K$, $l=e,\mu$. We identify several null tests of the standard model (SM). Notably, the

TLDR
It is shown that in new physics models generating CP violating ΔC=1 chromomagnetic dipole operators, sizable direct CP asymmetries in radiative D→P(+)P(-)γ decays (P=π, K), with M(PP) close to the ρ or the φ peak, can be expected.
