TL;DR: In this article, a simple quark-diquark model for the baryons is constructed as a partial solution to the well known missing resonances problem, and a complete classification of baryonic states is given and the spectrum is calculated through a mass formula built to reproduce the rotational and vibrational Regge trajectories.
Abstract: A simple quark-diquark model for the baryons is constructed as a partial solution to the well known missing resonances problem. A complete classification of the baryonic states in the quark-diquark framework is given and the spectrum is calculated through a mass formula built to reproduce the rotational and vibrational Regge trajectories.

TL;DR: In this paper, the bound state of two massive constituent gluons is studied in the potential approach by solving Relativistic quasi-classical wave equation with the QCD-inspired scalar potential in the complex plane.
Abstract: Bound state of two massive constituent gluons is studied in the potential approach. Relativistic quasi-classical wave equation with the QCD-inspired scalar potential is solved by the quasi-classical method in the complex plane. Glueball masses are calculated with the help of the universal mass formula. The hadron Regge trajectories are given by the complex non-linear function in the whole region of the invariant variable $t$. The Chew-Frautschi plot of the leading glueball trajectory, $\alpha_P(t)$, has the properties of the t-channel Pomeron, which is dual to the glueball states in the s channel. The imaginary part of the Pomeron is also calculated.

TL;DR: In this paper, the transformation properties of extremal N = 2 black hole solutions in S-T-U-like models under S and T duality are discussed, and a conjecture for the one-loop corrected entropy is made.
Abstract: We discuss the transformation properties of classical extremal N=2 black hole solutions in S-T-U like models under S and T duality. Using invariants of (subgroups of) the triality group, which is the symmetry group of the classical BPS mass formula, the transformation properties of the moduli on the event horizon and of the entropy under these transformations become manifest. We also comment on quantum corrections and we make a conjecture for the one-loop corrected entropy.

TL;DR: In this article, the authors generalize Schwinger's original mass formula to the case of an additional isosinglet mixing with the nonet mesons, and then make further generalization to either (i) an arbitrary number of additional ISs mixing with nonet meshes, or (ii) an arbitrarily number of mesons mixing with an ISS.

TL;DR: In this paper, a numeric formula for the masses of composite particles made of three quarks is presented, which uses Discontinuous Quantum Numbers (DQN) and achieves an accuracy of at least 3 decimal places.
Abstract: A numeric formula for the masses of composite particles made of three quarks is presented. The formula, which uses “discontinuous” quantum numbers, predicts the masses of 13 baryons and one lepton (the tau particle), with an accuracy of, at least, 3 decimal places. The maximum accuracy of the formula is 5 decimal places. The formula suggests the existence of a general formula for the mass of all known particles, which is yet, to be discovered.
