“…Bottom production at hadron colliders was addressed first in the late 1980s at the CERN SppS. The UA1 Collaboration investigated bottom production at high p t (p t > m b , where m b is the bottom quark mass) in pp collisions at √ s = 546 GeV and 630 GeV [131,132]. For this purpose, events containing single high-p t muons (10 < p µ t < 40 GeV/c) together with a jet or events containing dimuon pairs (2 < m µµ < 35 GeV/c 2 ) were selected.…”

Hadrons carrying open heavy flavor, i.e. single charm or bottom quarks, are among the key diagnostic tools available today for the hot and dense state of strongly interacting matter which is produced in collisions of heavy atomic nuclei at ultra-relativistic energies. First systematic heavy-flavor measurements in nucleus-nucleus collisions and the reference proton-proton system at Brookhaven National Laboratory's (BNL) Relativistic Heavy Ion Collider (RHIC) have led to tantalizing results. These studies are now continued and extended at RHIC and at CERN's Large Hadron Collider (LHC), where considerably higher collision energies are available. This review focuses on experimental results on open heavy-flavor observables at RHIC and the LHC published until July 2012. Yields of heavy-flavor hadrons and their decay products, their transverse momentum and rapidity distributions, as well as their azimuthal distributions with respect to the reaction plane in heavy-ion collisions are investigated. Various theoretical approaches are confronted with the data and implications for the properties of the hot and dense medium produced in ultra-relativistic heavy-ion collisions are discussed.

In these lectures I review what has been learned from studies of b-quark decays, including semileptonic decays (V ub and V cb ), B o −B o mixing and rare B decays. Then a discussion on CP violation follows, which leads to a summary of plans for future experiments and what is expected to be learned from them.In higher order other terms have an imaginary part; in particular the V cd term becomes −λ − A 2 λ 5 (ρ + iη), which is important for CP violation in K o L decay.

Abstract:The production cross-section of B + mesons is measured as a function of transverse momentum p T and rapidity y in proton-proton collisions at centre-of-mass energy √ s = 7 TeV, using 2.4 fb −1 of data recorded with the ATLAS detector at the Large Hadron Collider. The differential production cross-sections, determined in the range 9 GeV < p T < 120 GeV and |y| < 2.25, are compared to next-to-leading-order theoretical predictions. The ATLAS collaboration 22 IntroductionThe b-hadron production cross-section has been predicted with next-to-leading-order (NLO) accuracy for more than twenty years [1, 2] and more recently it has been predicted with fixed order plus next-to-leading-logarithms (FONLL) calculations [3,4]. Several measurements were performed with proton-antiproton collisions by the UA1 collaboration at the SppS collider (CERN) at a centre-of-mass energy of √ s = 630 GeV [5, 6] and by the CDF and D0 collaborations at the Tevatron collider (Fermilab) at √ s = 630 GeV, 1.8 TeV and 1.96 TeV [7][8][9][10][11][12][13][14][15][16]. These measurements made a significant contribution to the understanding of heavy-quark production in hadronic collisions [17]. However, the dependence of the theoretical predictions for b-quark production on the factorisation and renormalisation scales and the b-quark mass m b [2] results in theoretical uncertainties of up to 40% and, therefore, it is important to perform precise measurements of b-hadron production crosssections. In addition, measurements of b-hadron production cross-sections are of theoretical interest at higher √ s [18] and for B mesons of higher transverse momentum (p T ) [19]. Measurements of the b-hadron production cross-section in proton-proton collisions at the Large Hadron Collider (LHC) provide further tests of QCD calculations for heavyquark production at higher centre-of-mass energies and in wider transverse momentum (p T ) and rapidity (y) ranges, thanks to the extended coverage and excellent performance of the LHC detectors. Recently the LHCb collaboration measured b-hadron production crosssections using B ± → J/ψ K ± , b → J/ψ X and semileptonic b-hadron decays in the forward -1 - JHEP10(2013)042rapidity region at √ s = 7 TeV [20][21][22]. The CMS collaboration measured the production cross-sections for B + , B 0 , B s mesons, Λ b baryons, and inclusive b-hadron production using b → J/ψ X decays, semileptonic decays, and b-hadron jets at √ s = 7 TeV [23][24][25][26][27][28][29][30]. ATLAS has measured b-hadron production cross-sections using semileptonic decays [31, 32], b → J/ψ X decays [33] and b-hadron jets [34].This paper presents a measurement of the B + production cross-section using the decay channel B + → J/ψK + → µ + µ − K + in pp collisions at √ s = 7 TeV, as a function of B + transverse momentum and rapidity. The ATLAS and CMS detectors provide coverage in the central rapidity region, so their measurements are complementary to the LHCb measurements. With 2.4 fb −1 of data collected by the ATLAS detector, this analysis extends the meas...
