Light beyond-Standard-Model particles X in the MeV-100 MeV mass range can be produced in the nuclear and hadronic reactions, but would have to decay electromagnetically. We show that the simple and well-understood low-energy hadronic processes can be used as a tool to study X production and decay. In particular, the pion capture process can be used in a new experimental set-up to search for...

particles, a well-motivated extension of the standard model. Detectors located downstream of an
intense proton beam that is striking a target may be exposed to a large flux of millicharged particles.
Millicharged particles interact primarily through low momentum exchange producing electron... -

Muon electron scattering experiments, like MUonE, offer an opportunity

for an improved measurement of the LO hadronic running of $\alpha$, resulting in a reduced theoretical uncertainty of the leading hadronic effects on the anomalous magnetic moment of the muon. In this talk I present the possible impact of BSM physics on this measurement. In particular I will answer the question if a BSM... -

The anomalous magnetic moments of the electron and the muon are interesting observables, since they can be measured with great precision and their values can be computed with excellent accuracy within the Standard Model (SM). The current experimental measurement of this quantities show a deviation of a few standard deviations with respect to the SM prediction, which may be a hint of new...

We consider a simple non-supersymmetric $SO(10)$ grand unification in which a successful unification of the gauge couplings is realized with a two-step symmetry breaking (SB), for example, the $SO(10)$ group is broken into an intermediate Pati-Salam group at $M_{\rm GUT} \simeq 10^{16}$ GeV, which is further broken into the Standard Model (SM) group at an intermediate scale $M_I \simeq...

Vector-like top partners are a common feature of composite Higgs and Little Higgs models, where they help with the hierarchy problem. Traditional top partners decay primarily into electroweak channels: $t h$, $t Z$, and $b W$. The LHC places lower limits for top partner masses of around 1.1-1.4 TeV from pair production searches, under the assumption of these traditional decay modes. In our...

We present a model using up-type vector like quark (VLQ) charged under an additional $U(1)_d$ gauge force, whose gauge boson is the dark photon $\gamma_d$. If the dark photon is much less massive than the standard model electroweak sector ($M_{\gamma_d} \ll M_Z$), the VLQs, which are pair produced via the strong force, predominately decay to dark photons and a dark Higgs that breaks the...
