64. M_W at Hadron Colliders: Theoretical Considerations

Tao Han

5/25/22, 1:53 PM

In light of the recent CDF result on the MW measurement at the Fermilab Tevatron, I discuss some implications from theoretical considerations. I first summarize the current global fit on the EW parameters from the PDG and observe the clear tension with the CDF MW measurement. I then discuss the transverse kinematical variables at hadron colliders, such as PT(e) and MT(en), from which the MW is...

17. The nCTEQ Project: revealing the fundamental character of the QCD strong force

Fred Olness (Southern Methodist University (US))

5/25/22, 2:16 PM

Science is entering a new era in the investigation of nuclear matter,
driven by a wealth of precision data from the JLab, HERA, RHIC, & LHC
experiments. The nCTEQ project employs advanced theoretical techniques
to analyze these data sets comprehensively. While this analysis is
performed within the framework of the QCD parton model, we leverage
methods and results from Lattice QCD, Machine...

46. Searching for New Interactions at Sub-micron Scale Using the Mossbauer Effect

Surjeet Rajendran

5/25/22, 2:39 PM

A new technique to search for new scalar and tensor interactions at the sub-micrometer scale is presented. The technique relies on small shifts of nuclear gamma lines produced by the coupling between matter and the nuclei in the source or absorber of a Mossbauer spectrometer. Remarkably, such energy shifts are rather insensitive to electromagnetic interactions that represent the largest...

27. The $H_0$ and $S_8$ tensions necessitate early and late time changes to $\Lambda$CDM

Steven Clark (Brown University)

5/25/22, 3:02 PM

The Hubble tension is a result of variations between the late-Universe measurements of $H_0$ and those inferred from early-Universe physics measurements. Many solutions have been proposed to address this tension; among the most successful are alterations to the early-Universe physics such as Early Dark Energy (EDE). However, each of these proposed solutions mitigate the tension at the expense...

12. Explaining lepton-flavor non-universality and self-interacting dark matter with L_mu - L_tau

Julian Heeck

Experimental hints for lepton-flavor universality violation in the muon's magnetic moment as well as neutral- and charged-current $B$-meson decays require Standard-Model extensions by particles such as leptoquarks that generically lead to unacceptably fast rates of charged lepton flavor violation and proton decay. We propose a model based on a gauged $U(1)_{L_\mu-L_\tau}$ that eliminates all...
