“…For Λ's, the decrease in yield at large rapidity is a direct consequence of the increased "stopping" of the projectile baryon resulting from the multiple interactions in the target nucleus [22]. The strong increase in production of strange particles at low rapidity is qualitatively consistent with previously observed trends in secondary particle production in p-A collisions [16,25,26]. We show in Fig.…”

“…3 over m ⊥ . The fits give inverse slopes, T , that vary from 0.05 GeV/c at low and high y to 0.14 GeV/c at mid-rapidity, consistent with proton spectra obtained from p-A collisions at a similar energy [16]. For N grey bins where we do not have enough statistics to perform the fits we directly sum over m ⊥ to obtain dn/dy.…”

“…The simpler final state of p-A collisions may allow the production rate for strange particles to be directly connected with the scattering dynamics of the incoming proton. Previously published p-A data [15,16] demonstrated an increase in the inclusive K/π ratio with increasing A at the AGS, suggesting that the strangeness enhancement mechanism is already at work in p-A collisions. A more thorough analysis [17] of inclusive data at higher energies [18] suggested no overall strangeness enhancement but a possible modest enhancement in Λ production offset by a decrease inK production.…”

The first detailed measurements of the centrality dependence of strangeness production in p-A collisions are presented. Λ and KS dn/dy distributions from 17.5 GeV/c p-Au collisions are shown as a function of "grey" track multiplicity and the estimated number of collisions, ν, made by the proton. The ν dependence of the Λ yield deviates from a scaling of p-p data by the number of participants, increasing faster than this scaling for ν ≤ 5 and saturating for larger ν. A slower growth in KS multiplicity with ν is observed, consistent with a weaker ν dependence of KK production than Y K production.

“…The custom physics model is described in detail in Refs. [125,50], and summarized as follows.Primary p − Be interactions at 8.9 GeV/c proton kinetic energy are parametrized in terms of double-differential inelastic cross-sections, [131,132,133,134,135,136,137,138] The multiplicity of each secondary species is obtained with respect to the total inelastic production cross-section by integrating the corresponding parametrized double-differential cross-sections over the MiniBooNE proton kinematic phase-space, accounting for other proton elastic and inelastic processes as well.Each generated secondary in the simulation is tracked through the beamline geometry until it decays (producing the neutrino beam) or gets absorbed. The simulation accounts for the effect of the magnetic horn, particle decays, as well as electromagnetic processes and hadronic interactions (both for primary protons and secondary particles) in the beamline geometry/materials, also defined within the simulation.…”

Searches for New Physics at MiniBooNE: Sterile Neutrinos and Mixing Freedom

The MiniBooNE experiment was designed to perform a search for ν µ → ν e oscillations in a region of ∆m 2 and sin 2 2θ very different from that allowed by standard, threeneutrino oscillations, as determined by solar and atmospheric neutrino experiments. This search was motivated by the LSND experimental observation of an excess of ν e events in aν µ beam which was found compatible with two-neutrino oscillations at ∆m 2 ∼ 1 eV 2 and sin 2 2θ < 1%. If confirmed, such oscillation signature could be attributed to the existence of a light, mostly-sterile neutrino, containing small admixtures of weak neutrino eigenstates. In addition to a search for ν µ → ν e oscillations, MiniBooNE has also performed a search forν µ →ν e oscillations, which provides a test of the LSND two-neutrino oscillation interpretation that is independent of CP or CP T violation assumptions. This dissertation presents the MiniBooNE ν µ → ν e andν µ →ν e analyses and results, with emphasis on the latter. While the neutrino search excludes the two-neutrino oscillation interpretation of LSND at 98% C.L., the antineutrino search shows an excess of events which is in agreement with the twoneutrinoν µ →ν e oscillation interpretation of LSND, and excludes the no oscillations hypothesis at 96% C.L. Even though the neutrino and antineutrino oscillation results from MiniBooNE disagree under the single sterile neutrino oscillation hypothesis, a simple extension to the model to include additional sterile neutrino states and the possibility of CP violation allows for differences between neutrino and antineutrino oscillation signatures. In view of that, the viability of oscillation models with one or two sterile neutrinos is investigated in global fits to MiniBooNE and LSND data, with and without constraints from other oscillation experiments with similar sensitivities to those models. A general search for new physics scenarios which would lead to effective non-unitarity of the standard 3×3 neutrino mixing matrix, or mixing freedom, is also performed using neutrino and antineutrino data available from MiniBooNE.Thesis Supervisor: Janet M. Conrad Title: Professor of Physics Acknowledgments I owe this work to my advisor, Janet Conrad. Janet, you have been not only an unending source of inspiration for me these past five years, but also the reason I joined neutrino physics in the first place. Our very first meeting during the Columbia graduate student open house in 2005 was what introduced me to the excitement of neutrinos, while our interaction since then has made me appreciate the richness of this field. Thank you for the opportunity of becoming your advisee, and for your guidance and dedication over these past five years.I can't express how grateful I am to all the people I've worked most closely with during these past five years: I must begin with Michel Sorel, who has been like an older brother to me since the summer of 2005, introducing me to his work on sterile neutrinos and supporting me as I followed in his footsteps; Mike Shaevitz, for looking o...

Transport model calculations of deuteron production in relativistic hadron and heavy‐ion collisions

et al. 2019

The production of deuterons and heavy clusters such as triton and helium (or even hypertriton) has gained increased attention during the last years. This attention was mainly stimulated by the recent hypertriton data and has led to the question of whether cluster production is driven by coalescence of its constituents or by thermal emission of the cluster itself. Here, we explore the cluster production by coalescence using the Ultra-relativistic Quantum Molecular Dynamics model and a phase-space coalescence model. We explore deuteron production over a wide range of reactions and energies from √ s NN = 2 GeV to √ s NN = 2 TeV. Overall, we observe that coalescence leads to an excellent description of the deuteron yields and momentum distributions.
