2. Tetraquarks in the 1/N expansion: A new appraisal / Maiani, Luciano ; Polosa, Antonio D. ; Riquer, Veronica
We discuss the necessary, albeit not sufficient, conditions for tetraquark poles to occur in the 1/N expansion of QCD and find the minimum order at which such poles may appear. [...]

3. A theory of X and Z multiquark resonances / Maiani, Luciano ; Polosa, Antonio D. ; Riquer, Veronica
We introduce the hypothesis that diquarks and antidiquarks in tetraquarks are separated by a potential barrier. [...]

4. A new look at the Y tetraquarks and Ωc baryons in the diquark model / Ali, Ahmed ; Maiani, Luciano ; Borisov, Anatoly V. ; Ahmed, Ishtiaq ; et al
We analyze the hidden charm P -wave tetraquarks in the diquark model, using an effective Hamiltonian incorporating the dominant spin–spin, spin–orbit and tensor interactions. [...]

5. A note on polarized light from magnetars / Capparelli, L. M. ; Damiano, A. ; Maiani, L. ; Polosa, A. D.
In a recent paper it is claimed that vacuum birefringence has been experimentally observed for the first time by measuring the degree of polarization of visible light from a magnetar candidate, a neutron star with a magnetic field presumably as large as B∼1013G . [...]

6. Tetraquarks in the 1 /N expansion and meson-meson resonances / Maiani, L. ; Polosa, A. ; Riquer, V.
Diquarks are found to have the right degrees of freedom to describe the tetraquark poles in hidden-charm to open-charm meson-meson amplitudes. [...]

7. Y(4260)→γ+X(3872) in the diquarkonium picture / Chen, H.-X. ; Maiani, L. ; Polosa, A. D. ; Riquer, V.
The observed Y(4260)→γ+X(3872) decay is a natural consequence of the diquark–antidiquark description of Y and X resonances. [...]

9. The new pentaquarks in the diquark model / Maiani, L. ; Polosa, A.D. ; Riquer, V.
Pentaquark baryons are a natural expectation of an extended picture of hadrons where quarks and diquarks are the fundamental units. [...]

10. Fully covering the MSSM Higgs sector at the LHC / Djouadi, A. ; Maiani, L. ; Polosa, A. ; Quevillon, J. ; et al
In the context of the Minimal Supersymmetric extension of the Standard Model (MSSM), we reanalyze the search for the heavier CP-even H and CP-odd A neutral Higgs bosons at the LHC in their production in the gluon-fusion mechanism and their decays into gauge and lighter h bosons and into top quark pairs.
