Abstract Dark photons in the MeV to GeV range with kinetic mixing of the order of ≲ 10 −4 − 10 −3 can be produced in significant numbers at low energy colliders such as Belle II. Their decay length can be macroscopic raising the hope for a fa

Abstract Kinetic mixing between gauge fields of different U(1) factors is a well-studied phenomenon in 4d EFT. In string compactifications with U(1)s from sequestered D-brane sectors, kinetic mixing becomes a key target for the UV prediction of a phe

Abstract Time and space translation invariance, giving rise to energy and momentum conservation, are not only amongst the most fundamental but also the most generally accepted symmetry assumptions in physics. It is nevertheless prudent to put such as

We note the possibility to perform a parametrically improved search for gauged baryon (B) and baryon minus lepton (B−L) Dark Photon Dark Matter (DPDM) using auxiliary channel data from LISA Pathfinder. In particular we use the measurement of the di

Abstract It is widely believed that string theory easily allows for a QCD axion in the cosmologically favored mass range. The required small decay constant, f a ≪ M P , can be implemented by using a large compactification volume. This points to the

Abstract A finite axion–nucleon coupling, nearly unavoidable for QCD axions, leads to the production of axions via the thermal excitation and subsequent de-excitation of $$^{57}$$ 57 Fe isotopes in the sun. We revise the solar bound on this flux ad

Abstract Gravitational wave astronomy has recently emerged as a new way to study our Universe. In this work, we survey the potential of gravitational wave interferometers to detect macroscopic astrophysical objects comprising the dark matter. Startin

Abstract The axion is much lighter than all other degrees of freedom introduced by the Peccei-Quinn mechanism to solve the strong CP problem. It is therefore natural to use an effective field theory (EFT) to describe its interactions. Loop processes

We correct a number of figures in [1], in which the PYTHIA MC result of secondary π 0 mesons was displayed wrongly due to a missing factor of 2. Scrutinizing the corrected data-MC comparsion, we review and model the trigger condition used in the LEB

A significant number of high power proton beams are available or will go online in the near future. This provides exciting opportunities for new fixed target experiments and the search for new physics in particular. In this note we will survey these
