Autor: Carlos Bautista, Leonardo de Lima, Ricardo D’Elia Matheus, Eduardo Pontón, Leônidas A. Fernandes do Prado, Aurore Savoy-Navarro
Publikováno v: Journal of High Energy Physics, Vol 2021, Iss 3, Pp 1-73 (2021)
Abstract We study the production of t t ¯ h $$ t\overline{t}h $$ and t t ¯ hh $$ t\overline{t} hh $$ at hadron colliders, in the minimal Composite Higgs Models, based on the coset SO(5)/SO(4). We explore the fermionic representations 5 and 14. A de

Electroweak symmetric dark matter balls
Autor: Eduardo Pontón, Yang Bai, Bithika Jain
Publikováno v: Journal of High Energy Physics, Vol 2019, Iss 9, Pp 1-47 (2019)
Abstract In the simple Higgs-portal dark matter model with a conserved dark matter number, we show that there exists a non-topological soliton state of dark matter. This state has smaller energy per dark matter number than a free particle state and h

Mannheim Index versus APACHE II Score as Predictors of Mortality in Abdominal Sepsis in a 4th Level Ecuadorian Hospital
Autor: Marlon San Martin-Riera, Jonathan Coello-Vergara, Paul Vilatuña-Fustillos, Patricio Suquinagua-Mantilla, Kassandra Saavedra-Neira, Eduardo Pontón-Burgos, Francisco Paredes-Játiva, Nathaly Villacís-Flo

Introduction: In the last 30 years, scoring systems have been developed to determine patients’ illness severity or prognosis. In the present work, the role of the Mannheim Prognostic Index (MPI) to predict the risk of mortality, complications, prol

The radial excitation of the global symmetry-breaking vacuum in composite Higgs models, called the "global Higgs", has been recently a focus of investigation. In this paper we study the prospects for detecting this composite scalar at the 13 TeV LHC.

We present a simple microscopic realization of a pseudo-Nambu-Goldstone (pNGB) boson Higgs scenario arising from the breaking of $SO(5) \rightarrow SO(4)$. The Higgs constituents are explicitly identified as well as the interactions responsible for f

Light Kaluza–Klein states in Randall–Sundrum models with custodial SU(2)
Autor: Jose Santiago, Carlos E. M. Wagner, Eduardo Pontón, Marcela Carena
Publikováno v: Nuclear Physics B. 759:202-227
We consider Randall-Sundrum scenarios based on SU(2){sub L} x SU(2){sub R} and a discrete parity exchanging L with R. The custodial and parity symmetries can be used to make the tree level contribution to the T parameter and the anomalous couplings o

Electroweak phase transition, Higgs diphoton rate, and new heavy fermions
Autor: Hooman Davoudiasl, Eduardo Pontón, Ian M. Lewis
Publikováno v: Physical Review D. 87
We show that weak scale vector-like fermions with order one couplings to the Higgs can lead to a novel mechanism for a strongly first-order electroweak phase transition (EWPhT), through their tendency to drive the Higgs quartic coupling negative. The
