Matrix product state applications for the ALPS project

Thierry Giamarchi, Timothée Ewart, Sébastien Keller

The density-matrix renormalization group method has become a standard computational approach to the low-energy physics as well as dynamics of low-dimensional quantum systems. In this paper, we present a new set of applications, available as part of the ALP ...

Composite charge 8/3 resonances at the LHC

Francesco Riva, Thibaud Vantalon

In composite Higgs models with partial compositeness, the small value of the observed Higgs mass implies the existence of light fermionic resonances, the top partners, whose quantum numbers are determined by the symmetry (and symmetry breaking) structure o ...

Observation of a new charged charmoniumlike state in B-0 -> J/psi K- pi(+) decays

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Tara Nanut, Ji Hyun Kim, Donghyun Kim, Xiao Wang

We present the results of an amplitude analysis of B-0 --> J/psi K- pi(+) decays. A new charged charmoniumlike state Z(c)(4200)(+) decaying to J/psi pi(+) is observed with a significance of 6.2 sigma. The mass and width of the Z(c)(4200)(+) are 4196(-29-13 ...

Reaction Mechanism and Catalytic Fingerprint of Allantoin Racemase

Matteo Dal Peraro, Marco Stenta, Thomas Lemmin, Matteo Thomas Degiacomi, Christophe Bovigny

The stereospecific oxidative decomposition of urate into allantoin is the core of purine catabolism in many organisms. The spontaneous decomposition of upstream intermediates and the nonenzymatic racemization of allantoin lead to an accumulation of (R)-all ...

A first top partner hunter's guide

Riccardo Rattazzi, Andrea Wulzer, Andrea De Simone

We provide a systematic effective lagrangian description of the phenomenology of the lightest top-partners in composite Higgs models. Our construction is based on symmetry, on selection rules and on plausible dynamical assumptions. The structure of the res ...

Spontaneously broken conformal symmetry: dealing with the trace anomaly

Alexander Monin, Mikhail Chapochnikov, Roberta Armillis

The majority of renormalizable field theories possessing the scale invariance at the classical level exhibits the trace anomaly once quantum corrections are taken into account. This leads to the breaking of scale and conformal invariance. At the same time ...

Spectroscopy on Rydberg states of sodium atoms on the surface of helium nanodroplets

Marcel Drabbels, Evgeniy Loginov

One- and two-photon excitation spectra of sodium atoms on the surface of helium droplets are reported. The spectra are recorded by monitoring the photoionization yield of desorbed atoms as function of excitation frequency. The excitation spectra involving ...

The quantum numbers of the X(3872) meson are determined to be J(PC) = 1(++) based on angular correlations in B+ -> X(3872)K+ decays, where X(3872) -> pi(+) pi(-) j/psi and J/psi -> pi(+) mu(-). The data correspond to 1.0 fb(-1) of pp collisions collected b ...
