Testing the lepton content of the proton at HERA and EIC
Leandro Da Rold, Anibal D. Medina, Subhojit Roy +1
Although protons are baryons with an overall vanishing lepton number, they possess a non-trivial leptonic content arising from quantum fluctuations which can be described by lepton…
Improvement and generalization of ABCD method with Bayesian inference
Ezequiel Alvarez, Leandro Da Rold, Manuel Szewc +3
To find New Physics or to refine our knowledge of the Standard Model at the LHC is an enterprise that involves many factors. We focus on taking advantage of available information a…
Double Higgs production at the HL-LHC: probing a loop-enhanced model with kinematical distributions
Leandro Da Rold, Manuel Epele, Anibal D. Medina +2
We study di-Higgs production via gluon fusion at the high luminosity LHC in the presence of new physics, focusing on the final states. Taking a minimal set of three sca…
The flavor of a minimal composite leptoquark and the anomaly
Leandro Da Rold
Several experiments have measured a deviation in semileptonic decays, that point to new physics at the TeV scale violating lepton flavor universality. A scalar lepto…
Probing new physics with charge asymmetries in 2 same-sign leptons plus jets final states at the LHC
Ernesto Arganda, Leandro Da Rold, Aurelio Juste +2
We study the impact of new physics models in the charge asymmetry defined for LHC final states consisting of two same-sign leptons (2SS, with ) plus jets ($N_\text{jets…
A composite Froggatt-Nielsen model of flavor
Leandro Da Rold, Federico Lamagna
A natural composite Higgs demands the presence of light resonances at the TeV scale, that in general are in conflict with bounds from flavor and CP violation. We propose a composit…
Interpretation of LHC excesses in ditop and ditau channels as a 400-GeV pseudoscalar resonance
Ernesto Arganda, Leandro Da Rold, Daniel A. Díaz +1
Since the discovery in 2012 of the Higgs boson at the LHC, as the last missing piece of the Standard Model of particle physics, any hint of new physics has been intensively searche…
Measuring at LHC
Ezequiel Alvarez, Leandro Da Rold, Mariel Estevez +1
We propose a direct measurement of the CKM element at the LHC. Taking profit of the imbalance between and quark content in the proton, we show that a non-zero…
Graviton resonance phenomenology and a pNGB Higgs at the LHC
Ezequiel Alvarez, Leandro Da Rold, Javier Mazzitelli +1
We present an effective description of a spin two massive state and a pseudo Nambu-Goldstone boson Higgs in a two site model. Using this framework we model the spin two state as a…
Beautiful mirrors for a pNGB Higgs
Eduardo C. Andrés, Leandro Da Rold, Iván A. Davidovich
We consider one of the most significant deviations from the Standard Model: the forward-backward asymmetry of the b-quark measured at leptonic colliders. We investigate the possibi…
Minimal Composite Higgs Models at the LHC
Marcela Carena, Leandro Da Rold, Eduardo Ponton
We consider composite Higgs models where the Higgs is a pseudo-Nambu Goldstone boson arising from the spontaneous breaking of an approximate global symmetry by some underlying stro…
Single production of an exotic bottom partner at LHC
Ezequiel Alvarez, Leandro Da Rold, Juan Ignacio Sanchez Vietto
We study single production and detection at the LHC run II of exotic partners of the bottom quark. For masses larger than 1 TeV single production can dominate over pair production…
Up Asymmetries From Exhilarated Composite Flavor Structures
Leandro Da Rold, Cédric Delaunay, Christophe Grojean +1
We present a class of warped extra dimension (composite Higgs) models which conjointly accommodates the t\bar t forward-backward asymmetry observed at the Tevatron and the direct C…
Phenomenology of a light gluon resonance in top-physics at Tevatron and LHC
Ezequiel Alvarez, Leandro Da Rold, Juan Ignacio Sanchez Vietto +1
We present a phenomenological analysis of the recent Tevatron results on the forward-backward asymmetry and invariant-mass spectrum assuming a new contribution from an s…
A composite Higgs model analysis of forward-backward asymmetries in the production of tops at Tevatron and bottoms at LEP and SLC
Ezequiel Alvarez, Leandro Da Rold, Alejandro Szynkman
We perform a joint analysis of the prediction of composite Higgs models for the discrepancies of the forward-backward asymmetries of top and bottom quarks at Tevatron and LEP+SLC,…
Solving the A{FB}^b anomaly in natural composite models
Leandro Da Rold
The Standard Model with a light Higgs provides a very accurate description of the electroweak precision observables. The largest deviation between the Standard Model predictions an…
The Lepton Sector of a Fourth Generation
Gustavo Burdman, Leandro Da Rold, Ricardo D. Matheus
In extensions of the standard model with a heavy fourth generation one important question is what makes the fourth-generation lepton sector, particularly the neutrinos, so differen…
A Strongly Coupled Fourth Generation at the LHC
Gustavo Burdman, Leandro Da Rold, Oscar Eboli +1
We study extensions of the standard model with a strongly coupled fourth generation. This occurs in models where electroweak symmetry breaking is triggered by the condensation of a…
Renormalization of the S Parameter in Holographic Models of Electroweak Symmetry Breaking
Gustavo Burdman, Leandro Da Rold
We show that the S parameter is not finite in theories of electroweak symmetry breaking in a slice of anti--de Sitter five-dimensional space, with the light fermions localized in t…
Fermionic determinant with a linear domain wall in 2+1 dimensions
L. Da Rold, C. D. Fosco, A. P. C. Malbouisson
We consider a Dirac field in 2+1 Euclidean dimensions, in the presence of a linear domain wall defect in its mass, and a constant electromagnetic field. We evaluate the exact fermi…
Interacting fermions and domain wall defects in 2+1 dimensions
L. Da Rold, C. D. Fosco, A. Lopez
We consider a Dirac field in 2+1 dimensions with a domain wall like defect in its mass, minimally coupled to a dynamical Abelian vector field. The mass of the fermionic field is as…
