A positron trap is a powerful and adaptable tool for performing experiments with positrons and positronium. These devices use a strong magnetic field, a stepped potential well and Nitrogen and CF$_4$ buffer gas. Positrons are initially trapped via the electronic excitation of N$_2$, CF$_4$ is added for efficient cooling via vibrational and rotational excitations. This type of positron trap can...

The search for physics beyond the Standard Model (BSM) is one of the main goals of the LHC. Compared to standard proton-proton collision studies, heavy-ion collisions provide unique and complementary means to search for new phenomena. In particular, ultra-peripheral collisions (UPCs) of heavy ions offer a natural environment for the studies of photon-mediated processes, such as light-by-light...

Generation of ground state HD+ based on the [2+1’] resonance-enhanced threshold photoionization (RETPI) is provided for rovibrational transition frequency measurement. Using state-selected [1+1’] resonance-enhanced multiphoton dissociation, the yield of rovibrational ground state HD+ is evaluated. The state preparation of HD+ lay an important basis of the proceed measurement which detects the...

As the simplest neutral molecule, molecular hydrogen (H2) is a good testing ground for molecular quantum theory. Its dissociation energy D0 has become a benchmark value to test ab initio quantum molecular calculations. An experimental value for D0 can be obtained by relating the ionization energy of H2, to the ionization energy of atomic hydrogen and the dissociation energy of the H2 ion. By...

A number of experiments at CERN’s Antiproton Decelerator aim to measure the properties of antihydrogen to find structural differences hinting at CPT symmetry breaking that would explain the observed baryon-antibaryon asymmetry in our universe. These experiments detect antihydrogen through annihilation making the antiproton-nucleus ($\bar{p}A$) annihilation one of the main processes of...

The no-pair Dirac--Coulomb(--Breit) equation is solved with high-accuracy \cite{allorder,DiracCoulomb,Breit,LScoupling} to provide a starting point for a new alternative theoretical method in relation with high-resolution atomic and molecular spectroscopy \cite{QEDcorr}. The sub-parts-per-billion convergence of the energy is achieved by considering the relativistic symmetry with an $LS$...
