“…Accordingly, the D0 and TOTEM collaborations claimed that they accomplished the first experimental observation of the odderon! There were heated discussions and debates on this topic [939,940,941,942,943,944,945,946,947,948,949,950,951,952], which are mainly on the contribution of the odderon exchange in certain collisions. It is also important to directly study the odderon as well as the three-gluon glueball themselves.…”

The past decades witnessed the golden era of hadron physics. Many excited open heavy flavor mesons and baryons have been observed since 2017. We shall provide an updated review of the recent experimental and theoretical progresses in this active field. Besides the conventional heavy hadrons, we shall also review the recently observed open heavy flavor tetraquark states X(2900) and T + cc (3875) as well as the hidden heavy flavor multiquark states X(6900), P cs (4459) 0 , Z cs (3985) − , Z cs (4000) + , and Z cs (4220) + . We will also cover the recent progresses on the glueballs and light hybrid mesons, which are the direct manifestations of the non-Abelian SU (3) gauge interaction of the Quantum Chromodynamics in the low-energy region.

“…We emphasize that in the present paper it is not our purpose to perform a precision fit to the available experimental data on these quantities, say, from ISR to LHC energies. Such fits have been, for instance, given in [54][55][56][57][58][59][60]. Our aim here is to obtain a reasonable description of the data mainly at √ s = 13 TeV.…”

We discuss diffractive processes in proton-proton collisions at small momentum transfers without and with photon radiation. We consider the soft exclusive reactions pp → pp, p p → p p, and pp → ppγ within the tensor-pomeron and vector-odderon approach. We compare our results with the data for pp and p p total cross sections, for the ratio of real to imaginary part of the forward scattering amplitude, and for the elastic pp cross sections, especially those from TOTEM. To describe the low-energy data more accurately the secondary reggeons must be included. We write down the amplitudes for the photon bremsstrahlung in high-energy proton-proton collisions using the tensor-pomeron model. These results are relevant for the c.m. energies presently available at RHIC and at the LHC. We present predictions for the proposed measurements of soft photons with the planned future upgrade of the ALICE experiment at the LHC. We investigate the limits of applicability of the soft photon approximation (SPA) based on Low's theorem. The corresponding SPA results are compared to those obtained from our complete model. The regions of phase space are given quantitatively where SPA and our complete tensorpomeron results are close to each other. As an example, let k ⊥ , y, and ω, be the absolute value of the transverse momentum, the rapidity, and the energy of the photon, respectively, in the overall c.m. system. For the region 1 MeV < k ⊥ < 100 MeV and 3.5 < |y| < 5.0 we find that the SPA ansatz with only the pole terms ∝ ω −1 agrees at the percent level with our complete model result up to ω ∼ = 2 GeV.
