The study of exotic hadrons composed of four or more valence quarks is very challenging, both from theoretical and experimental perspectives. In this context, the particular class of states composed of two heavy antiquarks, bb, and two light quarks, ud is a promising system in the search for tetraquark candidates.In this talk, I present an approach to investigate such a system in the Born-Oppenheimer approximation using lattice-QCD static potentials.

In recent years, laser plasma acceleration (LPA) has become a promising alternative to conventional RF accelerators. Polarized beams areindispensable for many experiments in particle, atomic and nuclearphysics as well as in material science, where spin-dependent processesare to be studied. [...]

Laser Plasma Acceleration (LPA) with its extremely high gradientspromises compact accelerators and great progress has been made inthat direction. However, many applications in material science, nuclearand high energy physics require polarized electron beams.The motivation of the LEAP project at DESY is the first timedemonstration of LPA with polarization. [...]

In recent years, Laser Plasma Acceleration (LPA) has become a promising alternative to conventional RF accelerators. However, so far, it has only been theoretically shown that polarized LPA beams are possible. [...]

The latest results on searches for additional neutral and charged Higgs bosons at CMS are presented. The results include searches for additional Higgs bosons decays into pairs of fermions and charged Higgs boson decays with fermionic final states

We present the latest CMS results on the measurement of Higgs boson production with H->bb decays, considering production in association with a vector boson and via vector boson fusion or gluon fusion. In addition, we discuss the latest searches for H->cc decays..

The standard model (SM) predicts the Higgs boson to be even under charge-parity (CP) inversion. That makes any experimentally observed deviations from this hypothesis an intriguing hint towards new physics.In this talk we present the first measurement of the CP properties of the Higgs boson in its coupling to leptons.
