Building on the achievements of the Large Hadron Collider (LHC) and the projected reach of its high-luminosity upgrade (HL-LHC), the work of the Energy Frontier during the Snowmass 2021 community exercise has focused on building the case for future explorations at and above the TeV scale and has explored possible scenarios beyond the HL-LHC. In this talk I will present highlights of the main...
During the LHC RunII, both ATLAS and CMS experiments collected a large data set. Compared to the LHC RunI results, we have achieved much higher precision on measuring Higgs features like Yukawa couplings and the inclusive cross section. Meanwhile, we gained unprecedented high sensitivity to search for Higgs rare and exotic decays, and also for long-lived particles through Higgs portals. This...
Diffractive phenomena constitute a large fraction of interactions occurring in pp collisions at LHC. Because of their non-perturbative nature, the present understanding is still relatively poor and uncertain. One of the methods to study these processes is forward proton tagging. I will discuss the mechanism of the diffractive processes, recent results, and potential implications. The proton...
I will discuss new developments in the study of physics beyond the Standard Model, including motivations based on the observations of the existence of dark matter and dark sectors, neutrino masses, the baryon asymmetry of the Universe, the flavor structure of the Standard Model fermions, and others. I'll discuss many strategies to resolve the origin of these mysteries, including direct and...
"Particle production in the projectile hemisphere (forward region)
introduces a kinematic asymmetry where the light-cone momenta of
projectile partons are much greater than those of the partons in the
target. The natural description of such processes is in terms of
eikonal propagation of very energetic projectile partons through a
strong color field. This approach permits the resummation...
In recent years, increased attention has been devoted to the issue diversity, equity and inclusion (DEI) in societal engagements, in particular in the scientific disciplines. Many institutions have been making efforts—with various degrees of commitment and success—to improve DEI within the context of their institutional activities. During the recent particle physics prioritization exercise,...
Thanks to the high center-of-mass energy of the LHC, millions of top quarks have been produced and recorded, allow us to study the top quark related observables with a high precision. Deviations between theory predictions and experimental measurements in the top quark sector might indicate the first hints for new physics. This presentation focuses on the recent measurements at ATLAS and CMS...
Heavy ion collisions allow access to novel QCD and QED studies in a laboratory setting. Experimental collaborations actively pursue this opportunity at RHIC and the LHC, and this vibrant physics program continues to yield insights into the interactions and properties of excited nuclear matter. Precision measurements of the properties of quark-gluon plasma (QGP) and the strong electromagnetic...
In this talk I review the current state of precision QCD simulations for the LHC and beyond.
"PDFs play a key role across a broad range of areas of contemporary and future interest, and so the need for precision PDFs is only increasing. I will therefore review the current status of precision PDF determination, including advances on the experimental, methodological and theoretical fronts, as illustrated by examples from across the field. In the course of this I will focus on recent...
The Parton Distribution Functions(PDFs), as an essential ingredient of realistic cross section calculation in the framework of perturbative QCD, describe the x-dependent structure of hadron base on global analysis amount hard-scattering measurements. As a weakness, the PDFs from global analysis receive larger uncertainty when data is scarce. Starting from first principle operator definitions...
Spin is a unique probe to unravel the internal structure and QCD dynamics of nucleons. Exploration of the 3D spin structure of the nucleons is based on the complementarity of lepton scattering processes and purely hadronic probes. Some of the main questions that physicists have been trying to address in spin experiments involving different interactions and probes are: How does the spin of the...
Understanding the properties of nuclear matter and its emergence through the underlying partonic structure and dynamics of quarks and gluons requires a new experimental facility in hadronic physics known as the Electron-Ion Collider (EIC). The EIC will address some of the most profound questions concerning the emergence of nuclear properties by precisely imaging gluons and quarks inside...
The large dataset of about 3 ab-1 that will be collected at the High Luminosity LHC (HL-LHC) will be used to measure Higgs boson processes in detail. Studies based on current analyses have been carried out to understand the expected precision and limitations of these measurements. The large dataset will also allow for better sensitivity to di-Higgs processes and the Higgs boson self coupling....
Experimental and theoretical aspects of current W boson mass, status and future prospects for theory calculations and measurements.
One of the main tasks for modern QCD theory for colliders is to provide computations of the short-distance factors (typically, partonic cross sections) at high orders of perturbation theory. The past two decades have seen tremendous progress on the development of the theoretical framework needed to match the accuracy reached by the experiments. In this talk I will review the status and latest...
