Journal Article
Pascoli, S., Ruiz, R., & Weiland, C. (2018). Safe jet vetoes. Physics Letters B, 786, 106-113. https://doi.org/10.1016/j.physletb.2018.08.060

Central jet vetoes are powerful tools for reducing QCD background in measurements and searches for electroweak and colorless, new physics processes in hadron collisions. In this letter, we report the key findings of a new philosophy to designing sear... Read More about Safe jet vetoes.

Monojet signatures from heavy colored particles: future collider sensitivities and theoretical uncertainties (2018)
Journal Article
Chakraborty, A., Kuttimalai, S., Lim, S. H., Nojiri, M. M., & Ruiz, R. (2018). Monojet signatures from heavy colored particles: future collider sensitivities and theoretical uncertainties. The European Physical Journal C, 78(8), Article 679. https://doi.org/10.1140/epjc/s10052-018-6149-6

In models with colored particle Q that can decay into a dark matter candidate X, the relevant collider process pp → QQ¯ → X X¯ + jets gives rise to events with significant transverse momentum imbalance. When the masses of Q and X are very close, the... Read More about Monojet signatures from heavy colored particles: future collider sensitivities and theoretical uncertainties.

Lepton Number Violation: Seesaw Models and Their Collider Tests (2018)
Journal Article
Cai, Y., Han, T., Li, T., & Ruiz, R. (2018). Lepton Number Violation: Seesaw Models and Their Collider Tests. Frontiers in Physics, 6, Article 40. https://doi.org/10.3389/fphy.2018.00040

The Majorana nature of neutrinos is strongly motivated from the theoretical and phenomenological point of view. A plethora of neutrino mass models, known collectively as Seesaw models, exist that could generate both a viable neutrino mass spectrum an...

Lepton number violation at colliders from kinematically inaccessible gauge bosons (2017)
Journal Article
Ruiz, R. (2017). Lepton number violation at colliders from kinematically inaccessible gauge bosons. The European Physical Journal C, 77(6), Article 375. https://doi.org/10.1140/epjc/s10052-017-4950-2

We reevaluate the necessity of WRWR gauge bosons being kinematically accessible to test the left–right symmetric model (LRSM) at hadron colliders. In the limit that WRWR are too heavy, resonant production of sub-TeV Majorana neutrinos N can still pro...

A comprehensive framework for studying W′ and Z′ bosons at hadron colliders with automated jet veto resummation (2017)
Journal Article

The production of high-mass, color-singlet particles in hadron collisions is universally accompanied by initial state QCD radiation that is predominantly soft with respect to the hard process scale Q and/or collinear with respect to the beam axis. At... Read More about A comprehensive framework for studying W′ and Z′ bosons at hadron colliders with automated jet veto resummation.

Fully automated precision predictions for heavy neutrino production mechanisms at hadron colliders (2016)
Journal Article

Motivated by TeV-scale neutrino mass models, we propose a systematic treatment of heavy neutrino (N) production at hadron colliders. Our simple and efficient modeling of the vector boson fusion (VBF) Wγ → Nl and Nl þ nj signal definitions resolve col...

QCD corrections to pair production of Type III Seesaw leptons at hadron colliders (2015)
Journal Article

If kinematically accessible, hadron collider experiments provide an ideal laboratory for the direct production of heavy lepton partners in Seesaw models. In the context of the Type III Seesaw Mechanism, the O(αs) rate and shape corrections are presen... Read More about QCD corrections to pair production of Type III Seesaw leptons at hadron colliders.
