The ESSnuSB design study: overview and future prospects
ESSnuSB is a design study for an experiment to measure the CP violation in
the leptonic sector at the second neutrino oscillation maximum using a neutrino
beam driven by the uniquely powerful ESS linear accelerator. The reduced impact
of systematic errors on sensitivity at the second maximum allows for a very
precise measurement of the CP violating parameter. This review describes the
fundamental advantages of measurement at the 2nd maximum, the necessary
upgrades to the ESS linac in order to produce a neutrino beam, the near and far
detector complexes, the expected physics reach of the proposed ESSnuSB
experiment, concluding with the near future developments aimed at the project
realization.Comment: 19 pages, 11 figures; Corrected minor error in alphabetical ordering

DEVELOPMENT OF WIRELESS TECHNIQUES IN DATA AND POWER TRANSMISSION APPLICATION FOR PARTICLE-PHYSICS DETECTORS
In the WADAPT project described in this Letter of Intent, we propose to develop wireless techniques for data and power transmission in particle-physics detectors. Wireless techniques have developed extremely fast over the last decade and are now mature for being considered as a promising alternative to cables and optical links that would revolutionize the detector design. The WADAPT consortium has been formed to identify the specific needs of different projects that might benefit from wireless techniques with the objective of providing a common platform for research and development in order to optimize effectiveness and cost. The proposed R&D will aim at designing and testing wireless demonstrators for large instrumentation systems
Wireless Allowing Data and Power Transfer
International audienceThe WADAPT consortium (Wireless Allowing Data and Power Transfer) was created to study wireless (multi-gigabit) data transfer for high-energy physics applications (LoI, CERN-LHCC-2017-002; LHCC-I-028.-2017). Emerging millimetre wave technologies allow fast signal transfer and efficient partitioning of detectors in topological regions of interest. Large bandwidths are available at those frequencies, allowing very high data rates at short range and conveniently substituting a mass of materials (cables and connectors). The Wadapt initiative aims at building proof of concept for use in future HEP experiments. For vertex detectors at HL-LHC, the bandwidth of 60 GHz is adequate and commercial products are already available, providing 6 Gbps data links. Products have been tested for signal confinement, crosstalk, electromagnetic immunity and resistance to radiation. An HEP dedicated 60 GHz Integrated Chip is being built in Heidelberg, using 130 nm SiGe BICMOS technology. It should assess the feasibility and performance of the wireless link and establish solid foundation for designing the final reading system. At longer terms, 140 GHz bands could also be used for higher data rates (> 100 Gbps) for future FCC applications. Wireless reading could widespread to many detectors, with the possibility of adding intelligence on the detector to perform four-dimensional reconstruction of the traces and vertexes online, in order to attach the traces to their vertex with great efficiency even in difficult experimental conditions. The WADAPT project includes also a long-term step aimed at transmitting energy wirelessly. This would create a new paradigm for the transmission of data and power in particle physics detectors
Study of nonstandard interactions mediated by a scalar field at the ESSnuSB experiment
In this paper, we study scalar mediator induced nonstandard interactions (SNSIs) in the context of the ESSnuSB experiment. In particular, we study the capability of ESSnuSB to put bounds on the SNSI parameters and also study the impact of SNSIs in the measurement of the leptonic âą phase âą. Existence of SNSIs modifies the neutrino mass matrix and this modification can be expressed in terms of three diagonal real parameters (âą, âą, and âą) and three off-diagonal complex parameters (âą, âą, and âą). Our study shows that the upper bounds on the parameters âą and âą depend upon how Îâą231 is minimized in the theory. However, this is not the case when one tries to measure the impact of SNSIs on âą. Further, we show that the âą sensitivity of ESSnuSB can be completely lost for certain values of âą and âą for which the appearance channel probability becomes independent of âą
