Recently a new state of the bb system has been observed by the ATLAS Collaboration, with a mass of 10530±5±9 MeV. This state has been identified with the n = 3 P-wave radial excitations of the bb system with parallel quark spins, called χ b (3P ). The measured value of the mass corresponds to the average of the J = 0, 1 and 2 states, while the splittings of these states are not yet resolved. In this work we present predictions from different potentials models for the values of these splittings. I. INTRODUCTIONHeavy quarkonia, or mesons formed as heavy quark-antiquark bound states, constitute a valuable ground to study strong interactions, because they are related to both the perturbative and non-perturbative regimes of QCD. In heavy quarkonia energies are marginally high enough for perturbative methods to become useful, while the confining, non perturbative aspect of the interaction, is also of crucial importance.Recently a new state of the bb system has been observed by the ATLAS Collaboration, with a spin-weighted average ("barycenter") mass of 10530 ± 5 ± 9 MeV [1]. This state has been identified with the n = 3 radial excitation of the bb system with angular momentum numbers s = 1, ℓ = 1 (hence J = 0, 1, 2), called χ b (3P J ). The three states J = 0, 1, 2 are closely spaced in mass, so the measured value of the mass corresponds to their average, while the splittings of these states are not yet resolved. In this work we present predictions from different potentials models for the values of these splittings.Since the discovery of the J/ψ meson in 1974, understood as a (cc) system, many potential models have been proposed to describe the interaction between the quark and antiquark in a bound state . One of the first proposed models was the so called Cornell potential [2,5,7], which is a Coulomb-plus-linear term combination that takes into account general properties expected from the interquark interaction: a Coulombic behavior at short distances and a linear confining term at long distances, representing the perturbative one-gluon exchange and the non-perturbative chromoelectric flux tube of confinement, respectively. Other models based on phenomenological grounds include a logarithmic potential [4] and a non-integer power law potential [9]. Subsequently, elements from QCD were included in different ways in the potential formulation, from the inclusion of the running of the QCD coupling constant in the Coulombic interaction [6], to a derivation of the short distance quark-antiquark potential from perturbative QCD, where spin-dependent interactions naturally appear [8,[10][11][12][13][14][15]. A modification of the Cornell potential to take into account a saturation effect in the linearly growing confining part has also been proposed, inspired in lattice data [16,18,21]. In the context of these potential models, a successful description of many properties of quarkonia has been done, both for mass spectrum and decay widths. A comprehensive review of the status of heavy quarkonium can be found in Ref. [26]. For spe...

In this paper we consider a simple scenario where the Higgs boson and two vector resonances are supposed to arise from a new strong interacting sector. We use the ATLAS measurements of the dijet spectrum to set limits on the masses of the resonances. Additionally we compute the Higgs boson decay to two photons and found, when compare to the Standard Model prediction, a small excess which is compatible with ATLAS measurements. Finally we make prediction for Higgs-strahlung processes for the LHC running at 14 TeV. * alfonso.zerwekh@usm.cl
