2. New Directions in Political History

Author

History
Abstract

This roundtable takes up old themes and new perspectives in the field of political history. Scholars engage with six questions across three main categories: the scope of the field, current debates, and teaching. The first two questions ask how we should think about political power and the boundaries of what constitute political history. The section on current debates interrogates the relationship between governing and social movements during the GAPE, and how to situate the political violence of the January 6, 2021, Capitol Hill riot in historical perspective. The final section on teaching takes up two very different challenges. One question is a perennial concern about connecting with students in the classroom about political history. The other dilemma is how to respond to the growing cascade of censorship laws passed by state legislatures that prohibit the teaching of so-called “divisive concepts.”

6. POLITICAL CAPITALISM IN THE GILDED AGE: THE TAMMANY BANK RUN OF 1871

Abstract

The Tweed Ring spawned a vibrant financial sector that was integral to its brief success but has never been previously examined. William “Boss” Tweed and his allies employed banks controlled or comanaged by Tammany politicians to embezzle funds, build political alliances, and invest in a wide array of business ventures. The capital of these savings and commercial banks—city money, deposits from Catholic charities, and the savings of immigrant laborers—was accumulated through political channels. During their operation between 1867 and 1871, politician-bankers engaged in a mix of patronage deals and profit-driven financial speculation. In effect, Tammany banks were ground zero for the Ring's conversion of political hegemony into a windfall of economic capital that fueled party activities and buoyed personal fortunes. Importantly, the anti-Ring mobilization by upper-class reformers was more than a revolt of wealthy taxpayers concerned with abstract goals of good government or rescuing city credit; it was also a reaction by old-line bankers in direct competition with Tammany upstarts. A dramatic bank run catalyzed by reformers in November 1871 drove them into bankruptcy, bringing this novel experiment in political capitalism to an end.

9. From the Silver Screen to the Recall Ballot: Schwarzenegger as Terminator and Politician

Abstract

Arnold Schwarzenegger's electoral triumph in the 2003 California Recall should be explored through an analysis of his mobilization of the Terminator persona. If read as a social text, the Terminator stands out as an ideological “End of Labor” narrative about class violence as the United States shifted to a postindustrial economy. From the Hollywood box office to the California governor's office, Schwarzenegger's Terminator is the quintessential neoliberal Frankenstein, the labor-killing machine. The major thread running through both the films and Schwarzenegger's politics is a distinctly California brand of anti-labor populism, tailored for the state's neoliberal age of budget austerity and “permanent” fiscal and political crisis. Implications of how politicians present their political image to voters is considered, as well as prospects for the critical study of pop culture, political economy, and electoral politics.

10. Of Politicians, Populism, and Plates: Marketing the Body Politic

Abstract

In liberal democracies such as the United States, law emerges from a core ritual of the electoral-representation system, the theater of elections. From these cyclical rituals of consent, the "people" (re)discover political voice in embodied agents who ultimately do the work of governing. Lawmaking as a craft, or increasingly as a multibillion-dollar industry (CRP 201Oa, 20 1Ob), is performed by those who must first pass through an arena where political commitments are mediated by a space in which mass suffrage and mass consumerism dramatically converge. The experience of popular democracy for most citizens unfolds within this secular ritual that "makes" lawmakers. The very phantasmagoric spectacle of elections is the muse through which social relations are translated and reified into positive law. The state regulates everyday life through the discursive and material force of law. But what renders law so productive in the modern states quest to control, surveil, and differentiate populations? Per Max Weber's classic formulation, the state is the "monopoly of the legitimate use of physical force" (Weber 1947), a totalizing fantasy at once impossible to realize and yet utterly essential for statecraft to imagine. But law is not simply a unitary instrument to shape subjectivities, ideology, and cultural life. As Rosemary Coombe argues, law is nothing less than the "authoritative means and medium of a cultural politics in which the social is articulated." This social world itself "must be represented, performatively expressed, and institutionally inscribed" (1998, 36). Law then is also simultaneously a social, cultural, and political process, and one that leaves behind a genealogy of artifacts that help us to unpack the forces behind these modes of social regulation, ranging from outright coercion, to spontaneous consent, and counterhegemonic dissidence (Gewirtz 1996, 3). But if we begin our examination from within the courtroom, where law is interpreted, or even start our analysis within national political institutions, where law is drafted and executed, then our study falls prey to the tautological nature of state power: the law is the law because it is the law; it has a distinct legal dialect, formal procedures, and institutional avenues. Hegemonic power is always self-referential But the legal sphere especially strives for autonomy and relies on its ability to strictly separate those actions backed by the coercive apparatus of the state from those that are not. "Let literature borrow from law and life . . . but let law develop its own rules and structure and editing," declares Alan Dershowitz (1996, 104-5) in his polemic against the use of popular narrative as one strategy to combat systematic exclusions in the courtroom. For Dershowitz, the fantastic and the imaginary are external to law and should be permanently expunged in favor of the real, which must exist as a distinct category if there can be a potential for justice. Richard Sherwin, too, worries about policing the borders between law and its other, popular culture. When Law Goes Pop overflows with concerns about systemic "corruption," potential "imbalance," and the negative effects of "artificially enhanced passions," all pop-culturally driven tendencies that might potentially lead to "a state of affairs ... in which tyranny rules" (Sherwin 2000, 240-41). Sherwin observes that the culture industries progressively invade the courtroom, with an immeasurable capacity to shape popular legal consciousness and even judicial interpretation. One consequence, he suggests, is that justices, lawyers, and jurors alike are increasingly prone to conflate fiction with reality. Although Sherwin disavows the possibility of a total separation between popular culture and law, he does believe that the sheer proliferation of visual imagery in film, television, and on the Internet may have permanently forced law to a tipping point where it no longer finds legitimacy or consistency exclusively within its own domain. …

Abstract

We present the first measurement of elliptic ($v_2$) and triangular ($v_3$) flow in high-multiplicity $^{3}$He$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV. Two-particle correlations, where the particles have a large separation in pseudorapidity, are compared in $^{3}$He$+$Au and in $p$$+$$p$ collisions and indicate that collective effects dominate the second and third Fourier components for the correlations observed in the $^{3}$He$+$Au system. The collective behavior is quantified in terms of elliptic $v_2$ and triangular $v_3$ anisotropy coefficients measured with respect to their corresponding event planes. The $v_2$ values are comparable to those previously measured in $d$$+$Au collisions at the same nucleon-nucleon center-of-mass energy. Comparison with various theoretical predictions are made, including to models where the hot spots created by the impact of the three $^{3}$He nucleons on the Au nucleus expand hydrodynamically to generate the triangular flow. The agreement of these models with data may indicate the formation of low-viscosity quark-gluon plasma even in these small collision systems.

Abstract

We present azimuthal angular correlations between charged hadrons and energy deposited in calorimeter towers in central d+Au and minimum bias p+p collisions at sqrt[s_{NN}]=200 GeV. The charged hadron is measured at midrapidity |η| 2.75 is observed in d+Au collisions. Using the event plane method applied to the Au-going energy distribution, we extract the anisotropy strength v_{2} for inclusive charged hadrons at midrapidity up to p_{T}=4.5 GeV/c. We also present the measurement of v_{2} for identified π^{±} and (anti)protons in central d+Au collisions, and observe a mass-ordering pattern similar to that seen in heavy-ion collisions. These results are compared with viscous hydrodynamic calculations and measurements from p+Pb at sqrt[s_{NN}]=5.02 TeV. The magnitude of the mass ordering in d+Au is found to be smaller than that in p+Pb collisions, which may indicate smaller radial flow in lower energy d+Au collisions.

Abstract

We present midrapidity charged-pion invariant cross sections, the ratio of the pi(-) to pi(+) cross sections and the charge-separated double-spin asymmetries in polarized p + p collisions at root s = p + 200 GeV. While the cross section measurements are consistent within the errors of next-to-leading-order (NLO) perturbative quantum chromodynamics predictions (pQCD), the same calculations overestimate the ratio of the charged-pion cross sections. This discrepancy arises from the cancellation of the substantial systematic errors associated with the NLO-pQCD predictions in the ratio and highlights the constraints these data will place on flavor-dependent pion fragmentation functions. The charge-separated pion asymmetries presented here sample an x range of similar to 0.03-0.16 and provide unique information on the sign of the gluon-helicity distribution.

Abstract

The PHENIX experiment has measured open heavy-flavor production via semileptonic decay over the transverse momentum range 1 < p(T) < 6 GeV/c at forward and backward rapidity (1.4 < vertical bar y vertical bar < 2.0) in d + Au and p + p collisions at root s(NN) = 200 GeV. In central d + Au collisions, relative to the yield in p + p collisions scaled by the number of binary nucleon-nucleon collisions, a suppression is observed at forward rapidity (in the d-going direction) and an enhancement at backward rapidity (in the Au-going direction). Predictions using nuclear-modified-parton-distribution functions, even with additional nuclear-p(T) broadening, cannot simultaneously reproduce the data at both rapidity ranges, which implies that these models are incomplete and suggests the possible importance of final-state interactions in the asymmetric d + Au collision system. These results can be used to probe cold-nuclear-matter effects, which may significantly affect heavy-quark production, in addition to helping constrain the magnitude of charmonia-breakup effects in nuclear matter.

Abstract

The three gamma states, gamma (1S + 2S + 3S), are measured in d + Au and p + p collisions at root s(NN) = 200 GeV and rapidities 1.2 < vertical bar y vertical bar < 2.2 by the PHENIX experiment at the Relativistic Heavy Ion Collider. Cross sections for the inclusive gamma (1S + 2S + 3S) production are obtained. The inclusive yields per binary collision for d + Au collisions relative to those in p + p collisions (R-dAu) are found to be 0.62 +/- 0.26 (stat) +/- 0.13 (syst) in the gold-going direction and 0.91 +/- 0.33 (stat) +/- 0.16 (syst) in the deuteron-going direction. The measured results are compared to a nuclear-shadowing model, EPS09 [Eskola et al., J. High Energy Phys. 04 (2009) 065], combined with a final-state breakup cross section, sigma(br), and compared to lower energy p + A results. We also compare the results to the PHENIX J/psi results [Adare et al., Phys. Rev. Lett. 107, 142301 (2011)]. The rapidity dependence of the observed gamma suppression is consistent with lower energy p + A measurements. DOI: 10.1103/PhysRevC.87.044909

Abstract

Large parity-violating longitudinal single-spin asymmetries A(L)(e+) = 0.86(-0.14)(+0.30) and Ae(L)(e-) = 0.88(-0.71)(+0.12) are observed for inclusive high transverse momentum electrons and positrons in polarized p + p collisions at a center-of-mass energy of root s = 500 GeV with the PHENIX detector at RHIC. These e(+/-) come mainly from the decay of W-+/- and Z(0) bosons, and their asymmetries directly demonstrate parity violation in the couplings of the W-+/- to the light quarks. The observed electron and positron yields were used to estimate W-+/- boson production cross sections for the e(+/-) channels of sigma(pp -> W+X) X BR(W+ -> e(+) nu(e)) = 144.1 +/- 21.2(stat)(-10.3)(+3.4)(syst) +/- 21.6(norm) pb, and sigma(pp -> W-X) X BR(W- -> e(-) (nu) over bar (e)) = 3.17 +/- 12.1(stat)(-8.2)(+10.1)(syst) +/- 4.8(norm) pb.

Abstract

Large parity-violating longitudinal single-spin asymmetries A(L)(e+) = -0.86(-0.14) (+0.30) and A(L)(e-) = 0.88(-0.71) (+0.12) are observed for inclusive high transverse momentum electrons and positrons in polarized p+p collisions at a center-of-mass energy of sqrt[s] = 500 GeV with the PHENIX detector at RHIC. These e± come mainly from the decay of W± and Z0 bosons, and their asymmetries directly demonstrate parity violation in the couplings of the W± to the light quarks. The observed electron and positron yields were used to estimate W± boson production cross sections for the e± channels of σ(pp → W+ X) × BR(W+ → e+ ν(e)) = 144.1 ± 21.2(stat)(-10.3) (+3.4) (syst) ± 21.6(norm) pb, and σ(pp → W- X) × BR(W- → e- ν[over ¯](e)) = 31.7 ± 12.1(stat)(-8.2) (+10.1) (syst) ± 4.8(norm) pb.

Abstract

We present the first measurement of elliptic (v(2)) and triangular (v(3)) flow in high-multiplicity (3)He+Au collisions at √(s(NN))=200  GeV. Two-particle correlations, where the particles have a large separation in pseudorapidity, are compared in (3)He+Au and in p+p collisions and indicate that collective effects dominate the second and third Fourier components for the correlations observed in the (3)He+Au system. The collective behavior is quantified in terms of elliptic v(2) and triangular v(3) anisotropy coefficients measured with respect to their corresponding event planes. The v(2) values are comparable to those previously measured in d+Au collisions at the same nucleon-nucleon center-of-mass energy. Comparisons with various theoretical predictions are made, including to models where the hot spots created by the impact of the three (3)He nucleons on the Au nucleus expand hydrodynamically to generate the triangular flow. The agreement of these models with data may indicate the formation of low-viscosity quark-gluon plasma even in these small collision systems.

Abstract

We present azimuthal angular correlations between charged hadrons and energy deposited in calorimeter towers in central d+Au and minimum bias p+p collisions at sqrt[s&#95;{NN}]=200 GeV. The charged hadron is measured at midrapidity |η|<0.35, and the energy is measured at large rapidity (-3.7<η<-3.1, Au-going direction). An enhanced near-side angular correlation across |Δη|>2.75 is observed in d+Au collisions. Using the event plane method applied to the Au-going energy distribution, we extract the anisotropy strength v&#95;{2} for inclusive charged hadrons at midrapidity up to p&#95;{T}=4.5 GeV/c. We also present the measurement of v&#95;{2} for identified π^{±} and (anti)protons in central d+Au collisions, and observe a mass-ordering pattern similar to that seen in heavy-ion collisions. These results are compared with viscous hydrodynamic calculations and measurements from p+Pb at sqrt[s&#95;{NN}]=5.02 TeV. The magnitude of the mass ordering in d+Au is found to be smaller than that in p+Pb collisions, which may indicate smaller radial flow in lower energy d+Au collisions.

Abstract

The PHENIX experiment has measured open heavy-flavor production via semileptonic decay over the transverse momentum range 1 < p(T) < 6  GeV/c at forward and backward rapidity (1.4 < |y| < 2.0) in d+Au and p + p collisions at √sNN = 200  GeV. In central d+Au collisions, relative to the yield in p + p collisions scaled by the number of binary nucleon-nucleon collisions, a suppression is observed at forward rapidity (in the d-going direction) and an enhancement at backward rapidity (in the Au-going direction). Predictions using nuclear-modified-parton-distribution functions, even with additional nuclear-p(T) broadening, cannot simultaneously reproduce the data at both rapidity ranges, which implies that these models are incomplete and suggests the possible importance of final-state interactions in the asymmetric d + Au collision system. These results can be used to probe cold-nuclear-matter effects, which may significantly affect heavy-quark production, in addition to helping constrain the magnitude of charmonia-breakup effects in nuclear matter.

Abstract

Large parity-violating longitudinal single-spin asymmetries A(L)(e+) = -0.86(-0.14) (+0.30) and A(L)(e-) = 0.88(-0.71) (+0.12) are observed for inclusive high transverse momentum electrons and positrons in polarized p+p collisions at a center-of-mass energy of sqrt[s] = 500 GeV with the PHENIX detector at RHIC. These e± come mainly from the decay of W± and Z0 bosons, and their asymmetries directly demonstrate parity violation in the couplings of the W± to the light quarks. The observed electron and positron yields were used to estimate W± boson production cross sections for the e± channels of σ(pp → W+ X) × BR(W+ → e+ ν(e)) = 144.1 ± 21.2(stat)(-10.3) (+3.4) (syst) ± 21.6(norm)  pb, and σ(pp → W- X) × BR(W- → e- ν[over ¯](e)) = 31.7 ± 12.1(stat)(-8.2) (+10.1) (syst) ± 4.8(norm)  pb.
