The analysis compares the p pbar elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV. The two data sets disagree at the 3.4
sigma level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of
the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering, leading to a combined significance larger than 5 sigma. In a second part of the talk, we will describe the study of inclusive and exclusive diffraction
at low and high masses following the experience at HERA. Results on diffraction at the LHC will pave the road of future results to be obtained at the EIC and we will describe the present results and perspectives at the LHC. We will also mention briefly the
search for quartic anomalous couplings and axion-like particles using tagged protons in the final state and heavy ion interactions. We will finish by describing the ultra fast silicon detectors for timing measurements as well as for medical and cosmic ray
physics applications. </span><span style="font-size:12.0pt;font-family:"Times New Roman",serif;color:black"><o:p></o:p></span></p>
