Automated NNLL+NLO Resummation for Jet-Veto Cross Sections

Thomas Becher, Rikkert Frederix, Matthias Neubert +1

In electroweak-boson production processes with a jet veto, higher-order corrections are enhanced by logarithms of the veto scale over the invariant mass of the boson system. In thi…

Tenth-Order Electron Anomalous Magnetic Moment --- Contribution of Diagrams without Closed Lepton Loops

T. Aoyama, M. Hayakawa, T. Kinoshita +1

This paper presents a detailed account of evaluation of the electron anomalous magnetic moment a_e which arises from the gauge-invariant set, called Set V, consisting of 6354 tenth…

A global approach to top-quark flavor-changing interactions

Gauthier Durieux, Fabio Maltoni, Cen Zhang

We adopt a fully gauge-invariant effective-field-theory approach for parametrizing top-quark flavor-changing-neutral-current interactions. It allows for a global interpretation of…

Threshold Corrections to the Bottom Quark Mass Revisited

Archana Anandakrishnan, B. Charles Bryant, Stuart Raby

Threshold corrections to the bottom quark mass are often estimated under the approximation that tan enhanced contributions are the most dominant. In this work we revisit this co…

The SIMPlest Miracle

Yonit Hochberg, Eric Kuflik, Hitoshi Murayama +2

It has recently been proposed that dark matter could be a thermal relic of 3-to-2 scatterings in a strongly coupled hidden sector. We present explicit classes of strongly coupled g…

Precision Higgsstrahlung as a Probe of New Physics

Nathaniel Craig, Marco Farina, Matthew McCullough +1

A "Higgs factory", an electron-positron collider with center-of-mass energy of about 250 GeV, will measure the cross section of the Higgsstrahlung process, ,…

Constraining the Higgs-Dilaton with LHC and Dark Matter Searches

Aielet Efrati, Eric Kuflik, Shmuel Nussinov +2

We study a scenario in which the dilaton, a pseudo-Goldstone boson of the spontaneous breaking of conformal symmetry, provides a portal between dark matter and the visible sector.…

The Parton Model and its Applications

Tung-Mow Yan, Sidney D. Drell

This is a review of the program we started in 1968 to understand and generalize Bjorken scaling and Feynman's parton model in a canonical quantum field theory. It is shown that the…

Higgs Couplings and Phenomenology in a Warped Extra Dimension

Raoul Malm, Matthias Neubert, Christoph Schmell

We present a comprehensive description of the Higgs-boson couplings to Standard Model fermions and bosons in Randall-Sundrum (RS) models with a Higgs sector localized on or near th…

Higgs Production and Decay in Models of a Warped Extra Dimension with a Bulk Higgs

Paul R. Archer, Marcela Carena, Adrian Carmona +1

Warped extra-dimension models in which the Higgs boson is allowed to propagate in the bulk of a compact AdS space are conjectured to be dual to models featuring a partially com…

Spin-One Top Partner: Phenomenology

Jack H. Collins, Bithika Jain, Maxim Perelstein +1

Cai, Cheng, and Terning suggested a model in which the left-handed top quark is identified with a gaugino of an extended gauge group, and its superpartner is a spin-1 particle. We…

Cosmological Constraints on MFV SUSY

Michael Savastio

We study cosmological constraints in the context of -parity violating MFV SUSY and find it is driven to . These constraints are from two sources: first from the…

Nonzero in lepton models

Yuval Grossman, Wee Hao Ng

The simplest neutrino mass models based on symmetry predict at tree level, a value that contradicts recent data. We study models that arise from the spontaneous…

Dipole operator constraints on composite Higgs models

Matthias König, Matthias Neubert, David M. Straub

Flavour- and CP-violating electromagnetic or chromomagnetic dipole operators in the quark sector are generated in a large class of new physics models and are strongly constrained b…

Composite Higgses

Brando Bellazzini, Csaba Csáki, Javi Serra

We present an overview of composite Higgs models in light of the discovery of the Higgs boson. The small value of the physical Higgs mass suggests that the Higgs quartic is likely…

Higgs Couplings and Electroweak Phase Transition

Andrey Katz, Maxim Perelstein

We argue that extensions of the Standard Model (SM) with a strongly first-order electroweak phase transition generically predict significant deviations of the Higgs couplings to gl…

Neutrino masses in RPV models with two pairs of Higgs doublets

Yuval Grossman, Clara Peset

We study the generation of neutrino masses and mixing in supersymmetric R-parity violating models containing two pairs of Higgs doublets. In these models, new RPV terms $\hat H_{D_…
