Observability of an ultraheavy diquark decaying into vectorlike quarks at the LHC

Daniel C. Costache, Calin Alexa, Anca M. Dinu +4

We present a comprehensive analysis of the discovery reach and exclusion limits for an ultraheavy diquark scalar (7-9.5 TeV) decaying into a pair of vectorlike quarks (1.5-2 TeV) a…

Ultraheavy diquark decaying into vectorlike quarks at the LHC

Ioana Duminica, Calin Alexa, Ioan M. Dinu +2

We explore the discovery potential of an ultraheavy TeV) diquark scalar produced in the collisions of two up quarks at the LHC. Assuming that the diquark scalar decays int…

Yu-Shiba-Rusinov states in color superconducting quark matter

Virgil V. Baran, Jens Paaske

The high-density region of the QCD phase diagram displays an intricate competition between color superconductivity and the QCD Kondo effect due to color exchange in quark matter co…

Scalar sector of Type 2 Seesaw model explorations with multi-lepton final states

Călin Alexa, Otilia A. Ducu, Ana E. Dumitriu +5

Originally motivated for the generation of (Majorana) neutrino masses, the Type 2 Seesaw Model has also a rich extended Higgs sector with, if accessible at the LHC, a distinctive p…

Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +368

Dark matter particles could be superheavy, provided their lifetime is much longer than the age of the universe. Using the sensitivity of the Pierre Auger Observatory to ultra-high…

Quantum scale invariance in gauge theories and applications to muon production

Matthias Weißwange, Dumitru M. Ghilencea, Dominik Stöckinger

We discuss quantum scale invariance in (scale invariant) gauge theories with both ultraviolet (UV) and infrared (IR) divergences. Firstly, their BRST invariance is checked in two a…

Conformal mappings in perturbative QCD

Irinel Caprini

We discuss the method of conformal mappings applied to perturbative QCD. The approach is based on the Borel-Laplace integral regulated with the principal value prescription and the…

Standard Model in Weyl conformal geometry

D. M. Ghilencea

We study the Standard Model (SM) in Weyl conformal geometry. This embedding is natural and truly minimal {\it with no new fields} required beyond the SM spectrum and Weyl geometry.…

Analyticity and Regge asymptotics in virtual Compton scattering on the nucleon

Irinel Caprini

We test the consistency of the data on the nucleon structure functions with analyticity and the Regge asymptotics of the virtual Compton amplitude. By solving a functional extremal…

Test of analyticity and unitarity for the pion form-factor data around the resonance

B. Ananthanarayan, Irinel Caprini, Diganta Das

High-statistics data on the cross section and the pion vector form factor have been obtained recently by several collaborations. Unfortunately, there are some te…

Conformal mapping of the Borel plane: going beyond perturbative QCD

Irinel Caprini

The power corrections in the Operator Product Expansion (OPE) of QCD correlators can be viewed mathematically as an illustration of the transseries concept, which allows to recover…

The anomalous magnetic moment of the muon in the Standard Model

T. Aoyama, N. Asmussen, M. Benayoun +129

We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure con…

Higher-order perturbative coefficients in QCD from series acceleration by conformal mappings

Irinel Caprini

The present calculations in perturbative QCD reach the order for several correlators calculated to five loops, and the huge computational difficulties make unlikely the ful…
