413. Hints of lepton flavor non-universality in b decays

Matthew Scott Rudolph (Syracuse University (US))

12/07/2021, 10:10

talk

Experimental hints of lepton flavor non-universality in the decays of b-hadrons are an exciting sign of possible new physics beyond the Standard Model. Results from multiple experiments indicate that electrons, muons, and tau leptons may not be different only because of their masses. I will review the experimental situation of these “b-anomalies”, including recent developments and prospects...

417. Recent Progress in Measuring Mixing and CP Violation in B-meson Decays

Michael David Sokoloff (University of Cincinnati (US))

12/07/2021, 10:40

talk

This talk will review the role of the CKM matrix in governing meson-antimeson oscillations and CP violation in the Standard Model. Recent measurements of B_s oscillations and decays by LHCb, CMS, and ATLAS will be discussed in this context, as will be measurements of CP violation in B_d and B_u decays. The direct measurements of the CKM angle gamma (from decays produced by tree-level...

414. Hints for flavorful new physics

Wolfgang Altmannshofer (UC Santa Cruz)

12/07/2021, 11:10

talk

Flavor physics is addressing two complementary questions. First, what is the origin of the hierarchical flavor structure of the Standard Model quarks and leptons? Second, are there sources of flavor and CP violation beyond the Standard Model? I will discuss recent theoretical developments in this area, focusing mainly on the so-called "B-anomalies" -- persistent hints for the violation of...

418. The value of improving HEP outreach and how to participate

Don Lincoln (Fermilab)

12/07/2021, 11:40

talk

HEP is funded essentially entirely with public funds. Since there are many organizations that wish to receive federal funds, it is imperative that the HEP community raise its visibility among the general public. However, outreach to the public has long been neglected by the HEP community. In this talk, I will discuss the importance of outreach. I will also describe some of the methods that...

426. Cosmological Constraints from the Dark Energy Survey Year 3

Felipe Andrade-Oliveira (IFT UNESP/LIneA)

13/07/2021, 10:00

talk

The Dark Energy Survey has observed large scale structure data in 5000 sq. deg in sky. This effort was done in collaboration with hundreds of scientists culminating in the more accurate and precise constraints to date on the cosmology of the late-time Universe.

In this talk, I discuss the methodology and measurements in the third year of the Dark Energy Survey. I review the results from the...

425. Dark Matter Direct Detection

Rafael Lang

13/07/2021, 10:30

talk

424. (g-2)_\mu from lattice QCD and experiments: 4.2 sigma, indeed?

Zoltan Fodor (Hungarian Academy of Sciences (HU)), Zoltan Fodor (Wigner Research Centre for Physics (Wigner RCP) (HU))

13/07/2021, 11:00

talk

Twenty years ago, in an experiment at Brookhaven National Laboratory, physicists detected what seemed to be a discrepancy between measurements of the muon’s magnetic moment and theoretical calculations of what that measurement should be, raising the tantalizing possibility of physical particles or forces as yet undiscovered. The Fermilab team has just announced that their precise measurement...

427. DUNE and LBL Neutrino Program

Jose Maneira (LIP Lisboa), Jose Maneira (LIP-Lisboa)

13/07/2021, 11:30

talk

The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino experiment. Its main physics goals are the precise measurement of the neutrino oscillation parameters, in particular the violation of the charge-parity symmetry and the neutrino mass hierarchy. DUNE consists of a Far Detector (FD) complex with four multi-kiloton liquid argon detectors, and a Near...

430. Outlook for experimental high-pT LHC physics

Emanuele Usai (Brown University (US)), Emanuele Usai (Brown University)

14/07/2021, 10:00

talk

n this talk I will highlight recent results from the CMS and ATLAS Collaborations. Additionally, an overview will be given of the status of the two detectors during the LHC shutdown and the preparations for the upcoming data-taking period.

431. AI in HEP: Current Methods and Applications

Savannah Jennifer Thais (Princeton University (US))

14/07/2021, 10:30

talk

In recent years, Machine Learning (ML) and Artificial Intelligence (AI) methods have become ubiquitous in High Energy Physics research. Though initial implementations of ML for HEP focused mainly on supervised learning for classification problems like jet tagging or event selection, HEP researchers are increasingly employing cutting edge techniques for a wide range of applications and even...

415. New Adventures at the LHC

Zhen Liu (University of Minnesota)

14/07/2021, 11:00

talk

LHC provides one of the most potent and comprehensive physics tests in the TeV realm and is on its course to realize its full potential with upgrades. Beyond the vast class of successful searches, many new and exciting opportunities are emerging. In this talk, I will highlight several new angles and directions at the LHC, such as precision physics and exotic signatures, to motivate us for the...

416. Applying Lessons from Holography and Conformal Field Theory to Scattering

Sabrina Pasterski (MIT CMS)

14/07/2021, 11:30

talk

The holographic principle tells us that quantum theories of gravity behave like lower dimensional theories without gravity. We will review lessons learned from applying this principle in the context of gauge/gravity duality and black hole thermodynamics, show how it has guided recent efforts to recast scattering amplitudes in terms of a conformal field theory living on the celestial sphere,...
