Search for the decay D^0 → γγ and measurement of the branching fraction for D^0 → π^0π^0 [PDF]

open access: yes, 2012
We search for the rare decay of the D^0 meson to two photons, D^0→γγ, and present a measurement of the branching fraction for a D^0 meson decaying to two neutral pions, B(D^0→π^0π^0).

Fractional branching processes

open access: yes, 2011
Lo studio di processi di tipo nascita-morte è molto importante nell'analisi di fenomeni fisici quali, ad esempio, la dinamica di popolazioni oppure la diffusione di epidemie, o ancora il susseguirsi delle scosse di assestamento nello studio dei terremoti.

Measurement of the B 0 → ρ(770)0 γ branching fraction

open access: yesJournal of High Energy Physics
The ratio between the branching fractions of the B 0 → ρ(770)0 γ and B 0 → K *(892)0 γ decays is measured with proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated ...

Graphon branching processes and fractional isomorphism

open access: yes
In their study of the giant component in inhomogeneous random graphs, Bollobás, Janson, and Riordan introduced a class of branching processes parametrized by a possibly unbounded graphon. We prove that the tree structures underlying two such branching processes have the same distributions if and only if the corresponding graphons are fractionally ...

Convergence criteria of branched continued fractions

open access: yesResearches in Mathematics
The convergence criteria of branched continued fractions with N branches of branching and branched continued fractions of the special form are analyzed. The classical theorems of convergence of continued fractions that have become the subject of multidimensional generalizations are formulated.

Measurement of the branching fraction of D + → τ + ν τ

open access: yesJournal of High Energy Physics
By analyzing e + e − collision data with an integrated luminosity of 7.9 fb −1 collected with the BESIII detector at the center-of-mass energy of 3.773 GeV, the branching fraction of D + → τ + ν τ is determined as B $$ \mathcal{B} $$ = (9.9 ± 1.1stat ± 0.

Probing the Standard Model with electroweak penguin B decays

open access: yes, 2003
Recent branching fraction and asymmetry results of Electroweak Penguin B decays from BaBar, Belle and CLEO experiments are reviewed. While these branching fractions are consistent with the Standard Model expectations and are being used to extract heavy ...

SCET sum rules for Λ b → Λℓ + ℓ − , Λγ decays

open access: yesJournal of High Energy Physics
We construct light-cone sum rules for various types of effective form factors in the Λ b → Λℓ + ℓ − and Λ b → Λγ decays by analyzing vacuum-to-Λ b (or γ *-to-Λ b ) correlation functions with the light Λ-baryon interpolating current.
