Reframing Jet Physics with New Computational Methods
Kyle Cranmer, Matthew Drnevich, Sebastian Macaluso +1
We reframe common tasks in jet physics in probabilistic terms, including jet reconstruction, Monte Carlo tuning, matrix element - parton shower matching for large jet multiplicity,…
Thermal Relic Targets with Exponentially Small Couplings
Raffaele Tito D'Agnolo, Duccio Pappadopulo, Joshua T. Ruderman +1
If dark matter was produced in the early Universe by the decoupling of its annihilations into known particles, there is a sharp experimental target for the size of its coupling. We…
New Physics from High Energy Tops
Marco Farina, Cristina Mondino, Duccio Pappadopulo +1
Precision measurements of high energy top quarks at the LHC constitute a powerful probe of new physics. We study the effect of four fermion operators involving two tops and two lig…
Catching a New Force by the Tail
Simone Alioli, Marco Farina, Duccio Pappadopulo +1
The Large Hadron Collider (LHC) is sensitive to new heavy gauge bosons that produce narrow peaks in the dilepton invariant mass spectrum up to about TeV. s that…
Precision Probes of QCD at High Energies
Simone Alioli, Marco Farina, Duccio Pappadopulo +1
New physics, that is too heavy to be produced directly, can leave measurable imprints on the tails of kinematic distributions at the LHC. We use energetic QCD processes to perform…
A Fourth Exception in the Calculation of Relic Abundances
Raffaele Tito D'Agnolo, Duccio Pappadopulo, Joshua T. Ruderman
We propose that the dark matter abundance is set by the decoupling of inelastic scattering instead of annihilations. This coscattering mechanism is generically realized if dark mat…
The photo-philic QCD axion
Marco Farina, Duccio Pappadopulo, Fabrizio Rompineve +1
We propose a framework in which the QCD axion has an exponentially large coupling to photons, relying on the "clockwork" mechanism. We discuss the impact of present and future axio…
Energy helps accuracy: electroweak precision tests at hadron colliders
Marco Farina, Giuliano Panico, Duccio Pappadopulo +3
We show that high energy measurements of Drell-Yan at the LHC can serve as electroweak precision tests. Dimension-6 operators, from the Standard Model Effective Field Theory, modif…
Phases of Cannibal Dark Matter
Marco Farina, Duccio Pappadopulo, Joshua T. Ruderman +1
A hidden sector with a mass gap undergoes an epoch of cannibalism if number changing interactions are active when the temperature drops below the mass of the lightest hidden partic…
Cannibal Dark Matter
Duccio Pappadopulo, Joshua T. Ruderman, Gabriele Trevisan
A thermally decoupled hidden sector of particles, with a mass gap, generically enters a phase of cannibalism in the early Universe. The Standard Model sector becomes exponentially…
Freeze-In Dark Matter with Displaced Signatures at Colliders
Raymond T. Co, Francesco D'Eramo, Lawrence J. Hall +1
Dark matter, , may be generated by new physics at the TeV scale during an early matter-dominated (MD) era that ends at temperature . Compared to the conventio…
Radiative PQ Breaking and the Higgs Boson Mass
Francesco D'Eramo, Lawrence J. Hall, Duccio Pappadopulo
The small and negative value of the Standard Model Higgs quartic coupling at high scales can be understood in terms of anthropic selection on a landscape where large and negative v…
Multiverse Dark Matter: SUSY or Axions
Francesco D'Eramo, Lawrence J. Hall, Duccio Pappadopulo
The observed values of the cosmological constant {\it and} the abundance of Dark Matter (DM) can be successfully understood, using certain measures, by imposing the anthropic requi…
Les Houches 2013: Physics at TeV Colliders: New Physics Working Group Report
G. Brooijmans, R. Contino, B. Fuks +87
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 3--21 June, 2013). Our report includes new computatio…
Heavy Vector Triplets: Bridging Theory and Data
Duccio Pappadopulo, Andrea Thamm, Riccardo Torre +1
We introduce a model-independent strategy to study narrow resonances which we apply to a heavy vector triplet of the Standard Model (SM) group for illustration. The method is based…
Strong Higgs Interactions at a Linear Collider
Roberto Contino, Christophe Grojean, Duccio Pappadopulo +2
We study the impact of Higgs precision measurements at a high-energy and high-luminosity linear electron positron collider, such as CLIC or the ILC, on the parameter space of a str…
A modified naturalness principle and its experimental tests
Marco Farina, Duccio Pappadopulo, Alessandro Strumia
Motivated by LHC results, we modify the usual criterion for naturalness by ignoring the uncomputable power divergences. The Standard Model satisfies the modified criterion ('finite…
A minimally tuned composite Higgs model from an extra dimension
Duccio Pappadopulo, Andrea Thamm, Riccardo Torre
We construct and study the 5D realization of a composite Higgs model with minimal tuning. The Higgs is a (pseudo-)Goldstone boson from the spontaneous breaking of a global SO(5) sy…
On Partial Compositeness and the CP asymmetry in charm decays
Boaz Keren-Zur, Paolo Lodone, Marco Nardecchia +3
Recently, the LHCb and CDF collaborations reported the measure of an unexpectedly large direct CP asymmetry in D meson decays. In this paper we ask if new physics associated with P…
Strong, weak and flavor scalar triplets for the CDF Wjj anomaly
Duccio Pappadopulo, Riccardo Torre
A model describing the 4.1σ Wjj anomaly observed by the CDF experiment at the Tevatron collider is introduced. It features new scalar particles which are charged both under the SU(…
On the effect of resonances in composite Higgs phenomenology
Roberto Contino, David Marzocca, Duccio Pappadopulo +1
We consider a generic composite Higgs model based on the coset SO(5)/SO(4) and study its phenomenology beyond the leading low-energy effective lagrangian approximation. Our basic g…
Can CoGeNT and DAMA Modulations Be Due to Dark Matter?
Marco Farina, Duccio Pappadopulo, Alessandro Strumia +1
We explore the dark matter interpretation of the anomalies claimed by the DAMA and CoGeNT experiments, in conjunction with the various null direct-detection experiments. An indepen…
Implications of XENON100 and LHC results for Dark Matter models
Marco Farina, Mario Kadastik, Martti Raidal +3
We perform a fit to the recent Xenon100 data and study its implications for Dark Matter scenarios. We find that Inelastic Dark Matter is disfavoured as an explana- tion to the DAMA…
Lopsided Gauge Mediation
