Extensive experimental measurements of spin and azimuthal asymmetries in various processes have stimulated theoretical interest and progress in studies of the nucleon structure. Interpretation of experimental data in terms of parton distribution functions, generalized to describe transverse momentum and spatial parton distributions, is one of the main remaining challenges of modern nuclear physics. These new parton distribution and fragmentation functions encode the motion and the position of partons and are often referred to as three-dimensional distributions describing the three-dimensional (3D) structure of the nucleon. Understanding of the production mechanism and performing phenomenological studies compatible with factorization theorems using minimal model assumptions are goals of analysis of the experimental data. HERMES and COMPASS Collaborations and experiments at Jefferson Lab have collected a wealth of polarized and unpolarized Semi-Inclusive Deep Inelastic Scattering (SIDIS) data. These data play a crucial role in current understanding of nucleon spin-phenomena as they cover a broad kinematical range. The Jefferson Lab 12 GeV upgrade data on polarized and unpolarized SIDIS will have remarkably higher precision at large parton fractional momentum $x$ compared to the existing data. We argue that both experimental and phenomenological communities will benefit from development of a comprehensive extraction framework that will facilitate extraction of 3D nucleon structure, help understand various assumptions in extraction and data analysis, help to insure the model independence of the experimental data and validate the extracted functions. In this review we present the latest developments in the field of the spin asymmetries and discuss different components involved in precision extraction of 3D partonic distribution and fragmentation functions.

These lectures were presented at the 2019 CERN Latin-American School of High Energy Physics. They were centered on the experimental methods used in hadron colliders to advance our understanding in the field of high energy particle physics. From accelerators, to particle detector technologies, object identification and data analyses techniques, the lectures did not attempt to provide a comprehensive, in-depth technical background, but rather focused on an overview of experimental techniques that enabled our advances in supporting and challenging the predictions of the standard model. This document includes a selection of the material presented in the lectures, focusing on how advances in detector technologies and object identification enabled the development of increasingly sophisticated data analysis techniques. This writeup also includes an outlook to the future LHC program and beyond.

The study of the Quark-Gluon Plasma created in ultrarelativistic heavy-ion collisions at the CERN-LHC is complemented by reference measurements in proton-lead (p--Pb) and proton-proton (pp) collisions, where the effects of multiple-parton interactions and hadronization beyond independent string fragmentation can be investigated. In these proceedings, we present a Bayesian unfolding procedure to reconstruct the correlation between transverse momentum ($ p_{mathrm{T}}$) spectra of charged particles and the corresponding charged-particle multiplicities $N_{mathrm{ch}}$. The unfolded spectra are presented in single multiplicity ($Delta N_{mathrm{ch}}$ = 1) bins and are used to derive moments of the $p_{mathrm{T}} $ distributions. We illustrate the unfolding procedure of the $ p_{mathrm{T}} $ spectra with a Monte Carlo simulation for pp collisions at a centre-of-mass energy of $sqrt{mathrm{s}}= 5.02$ TeV.

The large data sample accumulated by the Belle experiment at KEKB asymmetric energy $e^+ e^-$ collider provides opportunities to study charmonia (bottomonia) and charmonium-like (bottomonium-like) exotic particles. In this review, we report recent results on these topics from Belle, including searches for $Bto h_c K$, $Bto Y(4260)K$, $Bto X(3872/3915) (to chi_{c1} pi^0 ) K$, $B^0 to X(3872) gamma$, $e^+e^- to gamma chi_{cJ}$ and a new measurement of the $e^+ e^-to Upsilon(nS) pi^+ pi^- (n=1,2,3)$ cross sections at energies from 10.52 to 11.02 GeV.

A complete, fundamental understanding of the proton must include knowledge of the underlying spin structure. The transversity distribution, $h_1left(xright)$, which describes the transverse spin structure of quarks inside of a transversely polarized proton, is only accessible through channels that couple $h_1 left(xright)$ to another chiral odd distribution, such as the Collins fragmentation function ($Delta^N D_{pi/q^uparrow}left(z,j_Tright)$). Significant Collins asymmetries of charged pions have been observed in semi-inclusive deep inelastic scattering (SIDIS) data. These SIDIS asymmetries combined with $e^+e^-$ process asymmetries have allowed for the extraction of $h_1left(xright)$ and $Delta^N D_{pi/q^uparrow}left(z,j_Tright)$. However, the current uncertainties on $h_1left(xright)$ are large compared to the corresponding quark momentum and helicity distributions and reflect the limited statistics and kinematic reach of the available data. In transversely polarized hadronic collisions, Collins asymmetries may be isolated and extracted by measuring the spin dependent azimuthal distributions of charged pions in jets. This thesis will report on the first statistically significant Collins asymmetries extracted from $sqrt{s}=200$ GeV hadronic collisions using $14$ pb$^{-1}$ of transversely polarized proton collisions at 57% average polarization.
对质子的一个完整的、基本的理解必须包括对潜在的自旋结构的了解。横向分布$h_1left(xright)$描述了横向极化质子内部夸克的横向自旋结构，只能通过耦合$h_1 left(xright)$和另一个手性奇分布(如柯林斯碎片函数($Delta^N D_{pi/q^uparrow}left(z,j_Tright)$))的通道来访问。在半包容深度非弹性散射(SIDIS)数据中观察到带电介子的显著柯林斯不对称性。这些SIDIS不对称与$e^+e^-$过程不对称相结合，可以提取$h_1left(xright)$和$Delta^N D_{pi/q^uparrow}left(z,j_Tright)$。然而，与相应的夸克动量和螺旋度分布相比，目前$h_1left(xright)$上的不确定性很大，并且反映了现有数据的有限统计和运动学范围。在横极化强子碰撞中，Collins不对称可以通过测量射流中带电介子的自旋相关方位角分布来分离和提取。本文将报道第一个统计上显著的柯林斯不对称，从$sqrt{s}=200$ GeV强子碰撞中提取，使用$14$ pb $^{-1}$的横向极化质子碰撞在57% average polarization.

We report a measurement of the flux-integrated $nu_{mu}$ charged-current cross sections on water, hydrocarbon, and iron in the T2K on-axis neutrino beam with a mean neutrino energy of 1.5 GeV. The measured cross sections on water, hydrocarbon, and iron are $sigma^{rm{H_{2}O}}_{rm{CC}}$ = (0.840$pm 0.010$(stat.)$^{+0.10}_{-0.08}$(syst.))$times$10$^{-38}$cm$^2$/nucleon, $sigma^{rm{CH}}_{rm{CC}}$ = (0.817$pm 0.007$(stat.)$^{+0.11}_{-0.08}$(syst.))$times$10$^{-38}$cm$^2$/nucleon, and $sigma^{rm{Fe}}_{rm{CC}}$ = (0.859$pm 0.003$(stat.) $^{+0.12}_{-0.10}$(syst.))$times$10$^{-38}$cm$^2$/nucleon respectively, for a restricted phase space of induced muons: $theta_{mu} $0.4 GeV/$c$ in the laboratory frame. The measured cross section ratios are ${sigma^{rm{H_{2}O}}_{rm{CC}}}/{sigma^{rm{CH}}_{rm{CC}}}$ = 1.028$pm 0.016$(stat.)$pm 0.053$(syst.), ${sigma^{rm{Fe}}_{rm{CC}}}/{sigma^{rm{H_{2}O}}_{rm{CC}}}$ = 1.023$pm 0.012$(stat.)$pm 0.058$(syst.), and ${sigma^{rm{Fe}}_{rm{CC}}}/{sigma^{rm{CH}}_{rm{CC}}}$ = 1.049$pm 0.010$(stat.)$pm 0.043$(syst.). These results, with an unprecedented precision for the measurements of neutrino cross sections on water in the studied energy region, show good agreement with the current neutrino interaction models used in the T2K oscillation analyses.

The measured cross sections on water, hydrocarbon, and iron are $sigma^{rm{H_{2}O}}_{rm{CC}}$ = (0.840$pm 0.010$(stat.)$^{+0.10}_{-0.08}$(syst.))$times$10$^{-38}$cm$^2$/nucleon, $sigma^{rm{CH}}_{rm{CC}}$ = (0.817$pm 0.007$(stat.)$^{+0.11}_{-0.08}$(syst.))$times$10$^{-38}$cm$^2$/nucleon, and $sigma^{rm{Fe}}_{rm{CC}}$ = (0.859$pm 0.003$(stat.) $^{+0.12}_{-0.10}$(syst.))$times$10$^{-38}$cm$^2$/nucleon respectively, for a restricted phase space of induced muons: $theta_{mu} $0.4 GeV/$c$ in the laboratory frame. The measured cross section ratios are ${sigma^{rm{H_{2}O}}_{rm{CC}}}/{sigma^{rm{CH}}_{rm{CC}}}$ = 1.028$pm 0.016$(stat.)$pm 0.053$(syst.), ${sigma^{rm{Fe}}_{rm{CC}}}/{sigma^{rm{H_{2}O}}_{rm{CC}}}$ = 1.023$pm 0.012$(stat.)$pm 0.058$(syst.), and ${sigma^{rm{Fe}}_{rm{CC}}}/{sigma^{rm{CH}}_{rm{CC}}}$ = 1.049$pm 0.010$(stat.)$pm 0.043$(syst.). These results, with an unprecedented precision for the measurements of neutrino cross sections on water in the studied energy region, show good agreement with the current neutrino interaction models used in the T2K oscillation analyses.","PeriodicalId":8429,"journal":{"name":"arXiv: High Energy Physics - Experiment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81827561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
