Search for Excited Quark Resonances in the Photon $+$ Jet Invariant Mass Spectrum at 13 TeV / Sharma, Varun (Delhi U.) /CMS
We present a search for excited quarks ( $q^{*}$ ) decaying into a photon and a hadronic jet in proton-proton collisions at $\sqrt{s} = 13\,$ TeV with the CMS experimentCMS experiment. High transverse momentum photons and jets are selected to search for a resonance peak in the continuous invariant mass distribution of the photon $+$ jet system. [...]

Resonance Measurements in p–Pb Collisions at $\sqrt{s_\mathrm{{NN}}}$ = 5.02 TeV with ALICE / Sahoo, Sarita (Bhubaneswar, Inst. Phys.) /ALICE
Hadronic resonances serve as unique probes in the study of hot and dense nuclear matter produced in heavy-ion collisions. Measurements of resonance production in pp and p–Pb collisions provide the reference for studies in heavy-ion collisions. [...]

Excited States Searches for Light and Heavy Flavour Quarks with CMS Data at $\sqrt{s} = 13$  TeV / Garg, Rocky Bala (Delhi U.) ; Sharma, Varun (Delhi U.) ; Choudhary, Brajesh C (Delhi U.)
In this paper, a search for excited states of light u,d and heavy b quark has been presented using the data collected by CMS detector at $\sqrt{s} = 13$  TeV in proton-proton collisons at the LHC. The resonance for these states have been probed in $\gamma $ +Jet final state and 95 $\%$ confidence level upper limits on the product of cross sectionCross section and branching fraction are evaluated as a function of the excited quark mass in the absence of any signal..

Search for the Pair-Production of First Generation Leptoquarks in pp Collisions at $\sqrt{s}$ = 13 TeV / Bhat, M A (Tata Inst.) ; Mahakud, B (Tata Inst.) ; Cooper, S I (Alabama U.) ; Mohanty, G B (Tata Inst.) ; Aziz, T (Tata Inst.) ; Rumerio, P (Alabama U.)
The quark and lepton sectors of the standard model (SM) are strikingly similar in terms of the number of particles and generations. This hints at a fundamental symmetry existing between the two sectors. [...]

Long Range Correlations in P–Pb Collisions at $\sqrt{s_\mathrm{{NN}}}$ = 5.02 TeV with ALICE / Koyithatta Meethaleveedu, Greeshma (Indian Inst. Tech., Mumbai) /ALICE Collaboration
Angular correlation measurements between charged particles revealed the existence of a double-ridge in p–Pb collisions. Similar correlations between particles separated by several units of pseudorapidity in Pb–Pb collisions were attributed to collectivity in heavy ion collisions. [...]

Operation and radiation damage studies of the ATLAS pixel detector / Rossini, L (Milan U. ; INFN, Milan) /ATLAS
The ATLAS pixel detector provides the innermost layers of the InnerDetector tracker. Due to its proximity to the collision region the pixel detector hasbeen exposed to considerable levels of radiation during its operation at the LHC,up to $2-10^{14}n_{eq}/cm^2$. [...]

The upgrade of the Inner Tracking System of the ALICE experiment / Ravasenga, I (INFN, Turin ; Turin Polytechnic) /ALICE
In 2021, for the third run of the CERN Large Hadron Collider(LHC), Pb-Pb collisions will be performed at a centre-of-mass energy per nucleon of 5.5 TeV, with an integrated luminosity of $6×10^{27}cm^{−2}s^{−1}$ and at an unprecedented interaction rate up to 50 kHz. To fulfil the requirements of the ALICE physics program for Run 3, the ALICE experiment at LHC is planning a major upgradeduring the Long Shutdown 2 of LHC in 2019–2020. [...]

The novel photon detectors based on MPGD technologies for COMPASS RICH-1 upgrade / Chatterjee, C (INFN, Trieste ; Trieste U.) /COMPASS RICH Group
The RICH-1 detector of the COMPASS experiment at CERN SPShas been upgraded for the 2016 physics run: four MWPC-based photon detectorshave been replaced by newly developed detectors based on MPGD technologies, fora total active area of 1.4 $m^2$. The new detector architecture consists in a hybrid com-bination of two layers of THGEMs, the first acting as a reflective photocathode, anda Micromegas equipped with a pad segmented anode. [...]
