1. Unquenching the Quark Model in a Nonperturbative Scheme / Entem, David R. ; Ortega, Pablo G. ; Fernández, Francisco
In recent years, the discovery in quarkonium spectrum of several states not predicted by the naive quark model has awakened a lot of interest. [...]

2. Calibrating the naïve Cornell model with NRQCD / Mateu, Vicent ; Ortega, Pablo G. ; Entem, David R. ; Fernández, Francisco
Along the years, the Cornell model has been extraordinarily successful in describing hadronic phenomenology, in particular in physical situations for which an effective theory of the strong interactions such as NRQCD cannot be applied. [...]

3. The Zc structures in a coupled-channels model / Ortega, Pablo G. ; Segovia, Jorge ; Entem, David R. ; Fernández, Francisco
The Zc(3900)±/Zc(3885)± and Zc(4020)± are two charmonium-like structures discovered in the πJ/ψ and D∗D¯(∗)+h.c. [...]

4. Contribution of constituent quark model cs¯ states to the dynamics of the Ds0∗(2317) and Ds1(2460) resonances / Albaladejo, Miguel ; Fernandez-Soler, Pedro ; Nieves, Juan ; Ortega, Pablo G.
The masses of the Ds0∗(2317) and Ds1(2460) resonances lie below the DK and D∗K thresholds respectively, which contradicts the predictions of naive quark models and points out to non-negligible effects of the D(∗)K loops in the dynamics of the even-parity scalar ( Jπ=0+ ) and axial-vector ( Jπ=1+ ) cs¯ systems. [...]

5. Counting states and the Hadron Resonance Gas: Does X(3872) count? / Ortega, Pablo G. ; Entem, David R. ; Fernández, Francisco ; Ruiz Arriola, Enrique
We analyze how the renowned X(3872), a weakly bound state right below the DD¯⁎ threshold, should effectively be included in a hadronic representation of the QCD partition function. [...]

6. Charmonium resonances in the 3.9 GeV/ c 2 energy region and the X (3915)/ X (3930) puzzle / Ortega, Pablo G. ; Segovia, Jorge ; Entem, David R. ; Fernández, Francisco
An interesting controversy has emerged challenging the widely accepted nature of the X(3915) and the X(3930) resonances, which had initially been assigned to the χc0(2P) and χc2(2P) cc¯ states, respectively. [...]
