Search for Second-Generation Leptoquarks in Proton-Antiproton Collisions
… describes the search for second-generation leptoquarks (LQ_2) in around 114 pb^-1 of proton-antiproton collisions, recorded with the D0 detector between September 2002 and June 2003 at a centre-of-mass energy of sqrt{s} = 1.96 TeV. The predictions of the Standard Model and models including …

Suche nach der Produktion von einzelnen Leptoquarks oder Squarks in Elektron-Photon-Wechselwirkungen mit dem OPAL-Experiment
… Daten wurde nach der Produktion von einzelnen Leptoquarks (LQ) und Squarks gesucht. <br>Leptoquarks bzw. Squarks sind neue Teilchen, die in Erweiterungstheorien des Standardmodells (SM) eingefuehrt werden: LQ kommen z.B. in Theorien vor, in denen die Leptonen und Quarks nicht mehr elementar …

Beyond the standard model searches with b-jets and hadronically decaying τ-leptons with the ATLAS detector
… as a search for third-generation scalar leptoquarks. Pair-produced third-generation scalar leptoquarks decaying to bτ bτ are excluded at 95% confidence level for mLQ < 1030 GeV.

Constraints on New Physics from Various Neutrino Experiments
… Lmu-Ltau, gauged B-3Lmu, and S1, S3, V1, V3 leptoquarks. We find that only the triplet leptoquark models can explain NuTeV and be compatible with the data from other experiments at the same time, and only if the components of the triplet have different masses. Then, we analyze the prospects …

Probing New Physics Through Third Generation Leptons
… from additional states like new vector bosons, leptoquarks or new scalar particles. These new states affect the semileptonic b → c and b → u transitions and gave rise to new physics beyond the standard model. We have presented the angular B¯ → D*+ τ − [special character omitted]τ with the most …

Phenomenological aspects of new physics at high energy hadron colliders
… symmetry breaking that contains new resonances, leptoquarks, that couple primarily to quarks and leptons of the third generation. In the prior model, we improve the current treatment of the W′ by considering interference ef- fects with the SM W and construct an event generator accurate to …

Holly Pacey and the Half-Spin Particles: Searching for new physics with leptons at the ATLAS experiment
Whilst the Large Hadron Collider (LHC) has spent just over a decade pushing experimental boundaries in energy and intensity of proton-proton collisions, it has yet to discover new physics beyond the Standard Model. The Standard Model remains one of the most robustly tested theories of all time, …
