**Introduction**
The physics at future high-energy lepton colliders requires jet energy reconstruction with unprecedented precision. Detector concepts for the International Linear Collider (ILC) and the Compact Linear Collider (CLIC) rely on Particle Flow Algorithms to achieve the necessary precision. This event reconstruction technique requires highly granular calorimeters to deliver...

The CALICE Digital Hadron Calorimeter (DHCAL) is a highly-granular 1 m$^3$ large prototype, based on Resistive Plate Chambers (RPCs) with digital readout of 1$\times$1 cm$^2$ pads. In special tests, 50 of its active layers were exposed to low energy particle beams, without interleaved absorber plates. The thickness of each layer corresponded approximately to 0.29 radiation lengths or 0.034...

A new reconstruction algorithm, ArborPFA, is developed to separate nearby
hadronic showers in the SDHCAL prototype. This intends to demonstrate the capability of
high granularity hadronic calorimeters such as the SDHCAL to efficiently apply Particle Flow
Algorithms. The reconstruction algorithm we present here uses the tree-like structure features of hadronic showers, that high granular...

The CALICE Semi-Digital Hadron Calorimeter technological prototype that was completed in 2011, is a sampling calorimeter using Glass Resistive Plate Chamber detectors as the active medium. This technology is one of the two options proposed for the hadron calorimeter of the International Large Detector for the International Linear Collider. The prototype was exposed to beams of muons, electrons...

Within the CALICE collaboration, several concepts for the hadronic calorimeter of a future linear collider detector are studied. After having demonstrated the capabilities of the measurement methods in *physics prototypes*, the focus now lies on improving their implementation in *engineering prototypes*, that are scalable to the full linear collider detector. The Analog Hadron Calorimeter...

The CALICE collaboration develops different high-granularity hadronic calorimeter technologies for a future linear collider. These technologies differ in active material, granularity and their readout and thus their energy reconstruction schemes. The Analogue Hadron Calorimeter (AHCAL), based on scintillator tiles with Silicon Photomultiplier readout, measures the signal amplitude of the...

Within the CALICE collaboration, several high granularity calorimeter prototypes optimised for particle flow reconstruction have been realised. One of the explored readout technologies consists of scintillating plastic elements read out by silicon photomultipliers (SiPMs), enabling unprecedented granularity in scintillator calorimeters. With this technology the ScECAL, an EM calorimeter with W...

A key ingredient to meet the requirements of the physics program at energy frontier machines such as future lepton colliders or the LHC are calorimeters with an unprecedented high granularity. These kind of calorimeters allow for the application of particle flow algorithms that rely on an excellent particle separation within the calorimeter.
The R&D program comprises an electromagnetic...

The successful running of the technological prototype of the Semi-Digital Hadronic CALorimter (SDHCAL) proposed to equip the future ILD detector of the ILC has provided excellent results in terms of energy linearity and resolution and also tracking capabilities. Stability with time of the prototype is also successfully tested.
To validate completely the SDHCAL option for ILD, a new R&D...
