General Analytical Conditions for Inflaton Fragmentation: Quick and Easy Tests for its Occurrence / Kim, Jinsu (CERN) ; McDonald, John (Lancaster U.)
Understanding the physics of inflaton condensate fragmentation in the early Universe is crucial as the existence of fragments in the form of non-topological solitons (oscillons or Q-balls) may potentially modify the evolution of the post-inflation Universe. Furthermore, such fragments may evolve into primordial black holes and form dark matter, or emit gravitational waves. [...]

An embedded domain specific language for general purpose vectorization / Karpinski, Przemyslaw (CERN) ; McDonald, John
Portable SIMD code generation is an open problem in modern High Performance Computing systems. Performance portability can already be achieved, however it might fail when user-framework interaction is required. [...]

Measurement of the quark to photon fragmentation function through the inclusive production of prompt photons in hadronic $Z^0$ decays / OPAL Collaboration
The inclusive production of prompt photons with energy above 10 GeV is measured using the OPAL detector in hadronic Z^0 decays at LEP. In contrast to previous measurements, the prompt photons were not required to be isolated. [...]

Search for Single Top Quark Production at LEP2 / OPAL Collaboration
A search for single top quark production via flavour changing neutral currents (FCNC) was performed with data collected by the OPAL detector at the e+e- collider LEP. Approximately 600 pb-1 of data collected at sqrt(s) = 189 - 209 GeV were used to search for the FCNC process e+ e- -> tc(u) -> bWc(u). [...]

Measurement of the Hadronic Cross-Section for the Scattering of Two Virtual Photons at LEP / OPAL Collaboration
The interaction of virtual photons is investigated using the reaction e+e- -> e+e- hadrons based on data taken by the OPAL experiment at e+e- centre-of-mass energies sqrt(s_ee)=189-209 GeV, for W>5 GeV and at an average Q^2 of 17.9 GeV^2. The measured cross-sections are compared to predictions of the Quark Parton Model (QPM), to the Leading Order QCD Monte Carlo model PHOJET to the NLO prediction for the reaction e+e- -> e+e-qqbar, and to BFKL calculations.

Thermally Generated Gauge Singlet Scalars as Self-Interacting Dark Matter / McDonald, John (CERN)
We show that a gauge singlet scalar S, with a coupling to the Higgs doublet of the form lambda_{S} S^{\dagger}S H^{\dagger}H and with the S mass entirely generated by the Higgs expectation value, has a thermally generated relic density Omega_{S} \approx 0.3 if m_{S} \approx (2.9-10.5)(Omega_{S}/0.3)^{1/5}(h/0.7)^{2/5} MeV for Higgs boson masses in the range 115 GeV to 1 TeV. Remarkably, this is very similar to the range (m_{S} = (6.6-15.4)\eta^{2/3} MeV) required in order for the self-interaction (\eta/4)(S^{\dagger}S)^{2} to account for self-interacting dark matter when \eta is not much smaller than 1.

Measurement of $Z/\gamma^{*}$ production in Compton scattering of quasi-real photons / OPAL Collaboration
The process e+ e- -> e+ e- Z/gamma* is studied with the OPAL detector at LEP at a centre of mass energy of sqrt(s) = 189 GeV. The cross-section times the branching ratio of the Z/gamma* decaying into hadrons is measured within Lorentz invariant kinematic limits to be (1.2 +/- 0.3 +/- 0.1) pb for invariant masses of the hadronic system between 5 GeV and 60 GeV and (0.7 +/- 0.2 +/- 0.1) pb for hadronic masses above 60 GeV.

Determination of the b Quark Mass at the Z Mass Scale / OPAL Collaboration
In hadronic decays of Z bosons recorded with the OPAL detector at LEP, events containing b quarks were selected using the long lifetime of b flavoured hadrons. Comparing the 3-jet rate in b events with that in d u,s and c quark events, a significant difference was observed. [...]

Search for Lepton Flavour Violation in $e^+e^-$ Collisions at $\sqrt{s}$ = 189 - 209 GeV / OPAL Collaboration
We search for lepton flavour violating events (e mu, e tau and mu tau) that could be directly produced in e+e- annihilations, using the full available data sample collected with the OPAL detector at centre-of-mass energies between 189 GeV and 209 GeV. In general, the Standard Model expectations describe the data well for all the channels and at each sqrt(s). [...]
