The difference in proton radii measured with $\mu p$ atoms and $ep$ scattering remains an unexplained puzzle. PSI MUSE proposal is to measure $e the same experiment at time. will determine cross sections, two-photon effects, form factors, independently for two reactions, allow results be compared reduced systematic uncertainties. These data should provide best test of lepton universality a date, about order magnitude improvement over previous tests. Measuring both particle polarities...
We present the first combined tuning, using , of four transverse kinematic imbalance measurements neutrino-hydrocarbon scattering, both with and without pion final states, from T2K MINERvA experiments. As a proof concept, we have simultaneously tuned initial state final-state interaction models (SF-CFG hA, respectively), producing new effective model that more accurately describes data.

In many extensions of the Standard Model, Higgs boson can decay into two light scalars, each which then subsequently photons. The underlying event is $h\ensuremath{\rightarrow}4\ensuremath{\gamma}$, but kinematics from boosted scalar decays combined with realistic detector resolutions may fail to register events in straightforward categories and thus be lost. this article, we investigate phase space for highly diphoton these exotic discuss search strategies that aim capture label difficult...
This review paper emphasizes the significance of microscopic calculations with quantified theoretical error estimates in studying lepton–nucleus interactions and their implications for electron scattering accelerator neutrino oscillation measurements. We investigate two approaches: Green’s Function Monte Carlo extended factorization scheme, utilizing realistic nuclear target spectral functions. In our study, we include relativistic effects validate inclusive cross section on carbon using...
The MUon Scattering Experiment, MUSE, at the Paul Scherrer Institute, Switzerland, investigates proton charge radius puzzle, lepton universality, and two-photon exchange, via simultaneous measurements of elastic muon-proton electron-proton scattering. experiment uses PiM1 secondary beam channel, which was designed for high precision pion scattering measurements. We review properties line established pions. discuss production processes that generate electron muon beams, simulations these...
To achieve its design goals, the next generation of neutrino-oscillation accelerator experiments requires percent-level predictions neutrino-nucleus cross sections supplemented by robust estimates theoretical uncertainties involved. The latter arise from both approximations in solving nuclear many-body problem and determination single- few-nucleon quantities taken as input methods. quantify types uncertainty, we compute flux-averaged double-differential using Green's function Monte Carlo...

The event topology is common experiments at a few-GeV energy range.

Axion-Like Particles (ALPs) are a generic, calculable, and well motivated extension of the Standard Model with far reaching phenomenology. ALPs that couple only to hypercharge represent one subset such models, coupling ALP both photons $Z$ boson. We examine current constraints on this class models an mass in 100 MeV GeV range, paying particular attention region between 10 GeV, portion parameter space which is ill constrained by experiments. show more than $10^{9}$ bosons produced Giga-Z mode...
Schwann cells are the myelinating glia of peripheral nervous system and dysfunction these causes motor sensory neuropathy. The transcription factor SOX10 is critical for cell development maintenance, many target genes encode proteins required function. Loss-of-function mutations in gene encoding myotubularin-related protein 2 (MTMR2) cause Charcot-Marie-Tooth disease type 4B1 (CMT4B1), a severe demyelinating neuropathy characterized by myelin outfoldings along nerves. Previous reports...

We investigate the ability to constrain these four-neutrino by their effect on flux of neutrinos originating from a galactic supernova. In dense medium core collapse supernova, new can have significant impact oscillations, leading changes at flavor evolution and spectra level. use simulations 13 solar mass, supernova 10 kpc away, numerically propagate through stellar taking into account...
We present the first global tuning, using GENIE, of four transverse kinematic imbalance measurements neutrino-hydrocarbon scattering, both with and without pion final states, from T2K MINERvA experiments. As a proof concept, we have simultaneously tuned initial state final-state interaction models (SF-LFG hA, respectively), producing new effective theory that more accurately describes data.
Due to the similarities between electron-nucleus ($eA$) and neutrino-nucleus scattering ($\nu A$), $eA$ data can contribute key information improve cross-section modeling in hence $\nu A$ event generators. However, compare generated events, either must be radiatively corrected or radiative effects need included We implemented a universal corrections program that used with all reaction mechanisms any generator. Our includes real photon radiation by incident scattered electrons, virtual...
Modeling lepton-nucleus scattering with the accuracy required to extract neutrino-oscillation parameters from long- and short-baseline experiments necessitates retaining most quantum-mechanical effects. One such effect is interference between one- two-body current operators in transition currents, which has been known enhance cross-sections, especially transverse kinematics. In this work, we incorporate spectral function formalism, combines relativistic currents kinematics an accurate...
Experimental searches for Axion-Like Particles (ALPs) which couple to the electroweak bosons span over a wide range of ALP masses, from MeV at beam-dump experiments, TeV LHC. Here we examine an interesting parameter space in couples only hypercharge. In GeV hundreds mass range, contribution light by scattering can be significant. By making simple kinematic cuts, show that ILC running $\sqrt{s} = 250\,\rm{GeV}$ or 500\,\rm{GeV}$ discover ALPs this masses with significantly smaller couplings...
The spatial response of pressurized helium-4 fast neutron scintillation detectors is characterized using collimated source measurements and MCNPX-PoliMi simulations. A method for localizing the position each detected event also demonstrated two-sided photomultiplier readout. Results show that particle interaction along axis active volume has a measurable effect on light detector. An algorithm presented uses probability distribution relative positions to perform localization, further...
