Diagonal form factors in Landau-Lifshitz models

open access: yesJournal of High Energy Physics, 2019
We perturbatively study form factors in the Landau-Lifshitz model and the generalisation originating in the study of the N $$ \mathcal{N} $$ = 4 super-Yang-Mills dilatation generator.

Dπ and DK semileptonic form factors with Nf = 2 + 1 + 1 twisted mass fermions [PDF]

open access: yes, 2018
We present a lattice determination of the vector and scalar form factors of the D → π(K)lv semileptonic decays, which are relevant for the extraction of the CKM matrix elements |Vcd| and |Vcs| from experimental data.

Hadron form factors and large-Nc phenomenology

open access: yesEPJ Web of Conferences, 2014
The half width rule provides a way to consider 1/Nc corrections to hadronic models containing resonances. Consequences of such ideas for hadron form factors and Regge trajectories are explored, with special emphasis on the possibility to describe the ...

Factorization of leading chiral logarithms in the pion form factors [PDF]

open access: yes, 2013
In the recently proposed framework of hard pion chiral perturbation theory, the leading chiral logarithms are predicted to factorize with respect to the energy dependence in the chiral limit.

Influence of the host related factors in the development of the hepatosplenic form of schistosomiasis mansoni

open access: yesMemorias do Instituto Oswaldo Cruz, 1992
The frequency of hepatosplenomegaly in endemic areas is not proportional to the fecal ova count. This may be explained by epidemiological genetic. The occurrence of two or more cases of schistosomal hepatosplenomegaly in nuclear family is much higher ...

Wilson loop form factors: a new duality

open access: yesJournal of High Energy Physics, 2018
We find a new duality for form factors of lightlike Wilson loops in planar N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory. The duality maps a form factor involving an n-sided lightlike polygonal super-Wilson loop together with m external on-shell states,
