The Dark Side of Electroweak Naturalness Beyond the MSSM
Genevieve Belanger, Cedric Delaunay, Andreas Goudelis
Weak scale supersymmetry (SUSY) remains a prime explanation for the radiative stability of the Higgs field. A natural account of the Higgs boson mass, however, strongly favors exte…
The Spinless Relativistic Kink-Like Problem
Wolfgang Lucha, Franz F. Schöberl
We constrain the possible bound-state solutions of the spinless Salpeter equation (the most obvious semirelativistic generalization of the nonrelativistic Schrödinger equation) wit…
Direct Detection Constraints on Dark Photon Dark Matter
Haipeng An, Maxim Pospelov, Josef Pradler +1
Dark matter detectors built primarily to probe elastic scattering of WIMPs on nuclei are also precise probes of light, weakly coupled particles that may be absorbed by the detector…
Beauty Vector Meson Decay Constants from QCD Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present the outcomes of a very recent investigation of the decay constants of nonstrange and strange heavy-light beauty vector mesons, with special emphasis on the ratio of any…
Aspects of anomalous glue
Steven D. Bass
Non-perturbative glue associated with gluon topology plays a vital role in determining the mass of the etaprime meson. We give an introduction to axial U(1) physics and explain how…
QCD Sum Rules for Heavy-Meson Decay Constants: Impact of Renormalization Scale and Scheme
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
Within the realm of QCD sum rules, one of the most important areas of application of this nonperturbative approach is the prediction of the decay constants of heavy mesons. However…
QCD symmetries and the eta and etaprime in nuclei
Steven D. Bass
We discuss the role of QCD symmetries in understanding the eta and etaprime mesons in nuclear media. Recent results on the etaprime mass in nuclei from the CBELSA/TAPS collaboratio…
Decay Constants of Beauty Mesons from QCD Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
Our recently completed analysis of the decay constants of both pseudoscalar and vector beauty mesons reveals that in the bottom-quark sector two specific features of the sum-rule p…
The Spinless Relativistic Yukawa Problem
Wolfgang Lucha, Franz F. Schöberl
Noticing renewed or increasing interest in the possibility to describe semirelativistic bound states (of either spin-zero constituents or, upon confining oneself to spin-averaged f…
Dark energy from the string axiverse
Marc Kamionkowski, Josef Pradler, Devin G. E. Walker
String theories suggest the existence of a plethora of axion-like fields with masses spread over a huge number of decades. Here we show that these ideas lend themselves to a model…
Improved cross-section predictions for heavy charged Higgs boson production at the LHC
Martin Flechl, Richard Klees, Michael Kramer +2
In most extensions of the Standard Model, heavy charged Higgs bosons at the LHC are dominantly produced in association with heavy quarks. An up-to-date determination of the next-to…
The Spinless Relativistic Hulthén Problem
Wolfgang Lucha, Franz F. Schöberl
The spinless Salpeter equation can be regarded as the eigenvalue equation of a Hamiltonian that involves the relativistic kinetic energy and therefore is, in general, a nonlocal op…
Charmed Pseudoscalar and Vector Mesons: a Comprehensive QCD Sum-Rule View of Their Decay Constants
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
In spite of undeniable similarities of the applied techniques, somewhat different challenges are encountered when extracting, from QCD sum rules derived from two-point correlators…
Semirelativistic Bound-State Equations: Trivial Considerations
Wolfgang Lucha, Franz F. Schöberl
Observing renewed interest in long-standing (semi-) relativistic descriptions of bound states, we would like to make a few comments on the eigenvalue problem posed by the spinless…
Cosmological Constraints on Very Dark Photons
Anthony Fradette, Maxim Pospelov, Josef Pradler +1
We explore the cosmological consequences of kinetically mixed dark photons with a mass between 1 MeV and 10 GeV, and an effective electromagnetic fine structure constant as small a…
Decay constants of the charmed vector mesons and from QCD sum rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present a sum-rule calculation of the decay constants of the charmed vector mesons and from the two-point correlator of vector currents. First, we show that the pe…
The Spinless Relativistic Woods-Saxon Problem
Wolfgang Lucha, Franz F. Schoberl
Motivated by the observation of a recent renewal of rather strong interest in the description of bound states by (semi-) relativistic equations of motion, we revisit, for the examp…
