QCD Constituent Counting Rules for Neutral Vector Mesons

Stanley J. Brodsky, Richard F. Lebed, Valery E. Lyubovitskij

QCD constituent counting rules define the scaling behavior of exclusive hadronic scattering and electromagnetic scattering amplitudes at high momentum transfer in terms of the tota…

Weak Vector Boson Production with Many Jets at the LHC TeV

F. R. Anger, F. Febres Cordero, S. Höche +1

Signatures with an electroweak vector boson and many jets play a crucial role at the Large Hadron Collider, both in the measurement of Standard-Model parameters and in searches for…

Elliptic polylogarithms and iterated integrals on elliptic curves II: an application to the sunrise integral

Johannes Broedel, Claude Duhr, Falko Dulat +1

We introduce a class of iterated integrals that generalize multiple polylogarithms to elliptic curves. These elliptic multiple polylogarithms are closely related to similar functio…

L. M. Abreu, F. S. Navarra, M. Nielsen +1

In this work we investigate the (called simply ) abundance in the hot hadron gas produced in the late stage of heavy ion collisions. We use effective Lagrangians…

Rare Boson Decays to a Hidden Sector

Nikita Blinov, Eder Izaguirre, Brian Shuve

We demonstrate that rare decays of the Standard Model boson can be used to discover and characterize the nature of new hidden-sector particles. We propose new searches for thes…

Momentum conservation and unitarity in parton showers and NLL resummation

Stefan Hoeche, Daniel Reichelt, Frank Siegert

We present a systematic study of differences between NLL resummation and parton showers. We first construct a Markovian Monte-Carlo algorithm for resummation of additive observable…

Millicharged Scalar Fields, Massive Photons and the Breaking of

Jennifer Rittenhouse West

Under the assumption that the current epoch of the Universe is not special, i.e. is not the final state of a long history of processes in particle physics, the cosmological fate of…

Parton Shower and NLO-Matching uncertainties in Higgs Boson Pair Production

Stephen Jones, Silvan Kuttimalai

We perform a detailed study of NLO parton shower matching uncertainties in Higgs boson pair production through gluon fusion at the LHC based on a generic and process independent im…

Differential Higgs production at N3LO beyond threshold

Falko Dulat, Bernhard Mistlberger, Andrea Pelloni

We present several key steps towards the computation of differential Higgs boson cross sections at NLO in perturbative QCD. Specifically, we work in the framework of Higgs-diff…

Resolving the SELEX--LHCb Double-Charm Baryon Conflict: The Impact of Intrinsic Heavy-Quark Hadroproduction and Supersymmetric Light-Front Holographic QCD

S. J. Brodsky, S. Groote, S. Koshkarev

In this paper we show that the intrinsic heavy-quark QCD mechanism for the hadroproduction of heavy hadrons at large can resolve the apparent conflict between measurements of…

Competing Forces in 5-Dimensional Fermion Condensation

Jongmin Yoon, Michael E. Peskin

We study fermion condensation in the Randall-Sundrum background as a setting for composite Higgs models. We formalize the computation of the Coleman-Weinberg potential and present…

Model-Independent Determination of the Triple Higgs Coupling at Colliders

Tim Barklow, Keisuke Fujii, Sunghoon Jung +2

The observation of Higgs pair production at high-energy colliders can give evidence for the presence of a triple Higgs coupling. However, the actual determination of the value of t…

Improved Formalism for Precision Higgs Coupling Fits

Tim Barklow, Keisuke Fujii, Sunghoon Jung +5

Future e+e- colliders give the promise of model-independent determinations of the couplings of the Higgs boson. In this paper, we present an improved formalism for extracting Higgs…

Ridge Production in High-Multiplicity Hadronic Ultra-Peripheral Proton-Proton Collisions

Stanley J. Brodsky, Stanislaw D. Glazek, Alfred S. Goldhaber +1

An unexpected result at the RHIC and the LHC is the observation that high-multiplicity hadronic events in heavy-ion and proton-proton collisions are distributed as two "ridges", ap…

Bootstrapping the QCD soft anomalous dimension

Øyvind Almelid, Claude Duhr, Einan Gardi +2

The soft anomalous dimension governs the infrared singularities of scattering amplitudes to all orders in perturbative quantum field theory, and is a crucial ingredient in both for…

Advantages of Unity With SU(4)-Color: Reflections Through Neutrino Oscillations, Baryogenesis and Proton Decay

Jogesh C. Pati

As a tribute to Abdus Salam, I recall the initiation in 1972-73 of the idea of grand unification based on the view that lepton number is the fourth color. Motivated by aesthetic de…

Gravity-Mediated Dark Matter Annihilation in the Randall-Sundrum Model

Thomas D. Rueter, Thomas G. Rizzo, JoAnne L. Hewett

Observational evidence for dark matter stems from its gravitational interactions, and as of yet there has been no evidence for dark matter interacting via other means. We examine m…

Thermal Dark Matter Below an MeV

Asher Berlin, Nikita Blinov

We consider a class of models in which thermal dark matter is lighter than an MeV. If dark matter thermalizes with the Standard Model below the temperature of neutrino-photon decou…

Implications of the Principle of Maximum Conformality for the QCD Strong Coupling

Alexandre Deur, Jian-Ming Shen, Xing-Gang Wu +2

The Principle of Maximum Conformality (PMC) provides scale-fixed perturbative QCD predictions which are independent of the choice of the renormalization scheme, as well as the choi…

Flavor Gauge Models Below the Fermi Scale

K. S. Babu, A. Friedland, P. A. N. Machado +1

The mass and weak interaction eigenstates for the quarks of the third generation are very well aligned, an empirical fact for which the Standard Model offers no explanation. We exp…

WIMPs with GUTs: Dark Matter Coannihilation with a Lighter Species

Asher Berlin

We propose a new thermal freeze-out mechanism for ultra-heavy dark matter. Dark matter coannihilates with a lighter unstable species, leading to an annihilation rate that is expone…
