Double Higgs production and quadratic divergence cancellation in little Higgs models with T-parity
(2006-05-01)
We analyze double Higgs boson production at the Large Hadron Collider in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related to those that cause the cancellation of ...
Hadron plus photon production in polarized hadronic collisions at next-to-leading order accuracy
(American Physical Society, 2011-04)
We compute the next-to-leading order QCD corrections to the polarized (and unpolarized) cross sections for the production of a hadron accompanied by an opposite-side prompt photon. This process, being studied at RHIC, ...
Identifying Multiquark Hadrons from Heavy Ion Collisions
(AMER PHYSICAL SOC, 2011)
Identifying hadronic molecular states and/or hadrons with multiquark components either with or without exotic quantum numbers is a long-standing challenge in hadronic physics. We suggest that studying the production of ...
Production and propagation of heavy hadrons in air-shower simulators
(Elsevier Science, 2013-05)
Very energetic charm and bottom hadrons may be produced in the upper atmosphere when a primary cosmic ray or the leading hadron in an extensive air shower collide with a nucleon. At E≈108 GeV their decay length becomes of ...
Hadronic high-energy gamma ray emission from microquasars
(IOP Publishing, 2005-06)
We present a hadronic model for gamma-ray production in the microquasar LS I +61 303. The system is formed by a neutron star that accretes matter from the dense and slow equatorial wind of the Be primary star. We calculate ...
Shining light on polarizable dark particles
(Springer, 2017-04-14)
We investigate the possibilities of searching for a self-conjugate polarizable particle in the self-interactions of light. We first observe that polarizability can arise either from the exchange of mediator states or as a ...
Total hadronic cross section and the elastic slope: An almost model-independent connection
(Elsevier Science BvAmsterdamHolanda, 2012)
Scale-invariant resonance tagging in multijet events and new physics in Higgs pair production
(2013-08-19)
We study resonant pair production of heavy particles in fully hadronic final states by means of jet substructure techniques. We propose a new resonance tagging strategy that smoothly interpolates between the highly boosted ...
Supersymmetric Higgs boson pair production at hadron colliders
(1999-10-01)
We study the pair production of neutral Higgs bosons through gluon fusion at hadron colliders in the framework of the minimal supersymmetric standard model. We present analytical expressions for the relevant amplitudes, ...
Stop-lepton associated production at hadron colliders
(Elsevier B.V., 2003-04-17)
At hadron colliders, the search for R-parity violating supersymmetry can probe scalar masses beyond what is covered by pair production processes. We evaluate the next-to-leading order SUSY-QCD corrections to the associated ...
