Searches for B and L violation in India

Searches for B and L violation in India Utpal Sarkar Physical Research Laboratory Ahmedabad, India February 11, 2011 Mini NANO Workshop 1

Prof. J. N. Goswami, Director, PRL Greetings on behalf of PRL, Prof. Goswami and myself to everyone present. Our first step would be to see if we can get some seed funds to look into the viability of the proposed project from technical angle. In India it is still being discussed seriously only within PRL. The coming 5 yr plan period, however, provide an opportunity to make a proposal with a PRL lead and all India character, as well as indicating possible international interest and hence this meeting has important significance.

The Physical Research Laboratory was established by Dr. Vikram A. Sarabhai “Countries have to provide facilities for its nationals to do front rank research within the resources that are available. It is equally necessary having produced the men who can do research, to organise task oriented projects for the nation’s practical problems. ” Work on cosmic rays, a prominent subject at that time, was started from the “RETREAT” in 1947.

First Ozone Measurement Station established at Mt. Abu in 1951 With rapidly expanding research activities, PRL needed its own campus. Foundation laid by Sir C. V. Raman in 1952 in the current premises. Inauguration of PRL Main Campus in 1954 by Pandit Jawaharlal Nehru. February 11, 2011 Mini NANO Workshop 5

Scientists from PRL initiated Space Science Research by contributing significantly to the scientific and technical developments. Thus PRL became the “cradle” of Indian Space Research Program. Drs. Sarabhai, Kalam, Nair and others Aryabhatta Satellite Rocket February 11, Launched from 2011 Thumba Mini NANO Workshop Balloon Launch 6

H 2 O OH A three colour composite of near-infrared reflected solar radiation for the lunar nearside measured by Moon Mineral Mapper payload onboard Chandrayaan 1. Blue colour indicates 3 micrometer absorption associated with the presence of OH/H 2 O that is most prominent at higher cooler Workshop latitudes. February 11, 2011 Mini NANO 8

Non-Accelerator Particle Physics Experiments February 11, 2011 Mini NANO Workshop 18

Atmospheric Neutrinos n n n Cosmic rays from outer space impinge on the atmosphere of the earth all the time They produce showers of charged particles in a cascade phenomenon The end products of these cascades also contain neutrinos of types ne and nm February 11, 2011 Mini NANO Workshop 19

First Detection of Atmospheric Neutrinos at KGF l The experiments were conducted by groups from TIFR, Durham University and Osaka University using basic trigger with scintillation counters and (NFT) for tracking detectors. Seven detectors were deployed at a depth of 2. 3 km in Heathcote shaft and Champion Reefs mines. The experiment discovered the first atmospheric neutrinos in an iron calorimeter here about the same time as a similar discovery in a mine in South Africa. February 11, 2011 Mini NANO Workshop 20

Proton Decay Experiment at KGF n n Six proton decay events were reported, three strong candidates with lifetime ~1031 yrs. Some experimental observations, called Kolar events, have yet to be explained. They suggest the existence of massive (>3 Ge. V) particles having a long life (10− 9 secs). These massive particles are also seen to decay into 2– 3 particles. February 11, 2011 Mini NANO Workshop 21

India-based Neutrino Observatory n 50, 000 ton magnetized iron particle physics calorimeter with glass Resistive Plate Chamber (RPC) technology as the sensor elements. n The detector was expected to start collecting data in the year 2012. Rescheduled to 2015. n The location of INO has attracted a lot of attention from the neutrino physics community as the distance between INO and CERN is very close to "Magic Baseline" - a distance at which the effect of the CP phase on the measurement of θ 13 is minimal. February 11, 2011 Mini NANO Workshop 22

n n The Primary goals of the INO : Unambiguous and more precise determination of Neutrino oscillation parameters using atmospheric neutrinos. Study of matter effects through electric charge identification, that may lead to the determination of the unknown sign of one of the mass differences. Study of charge-conjugation and charge parity (CP) violation in the leptonic sector as well as possible charge-conjugation, parity, time-reversal (CPT) violation studies. Study of Kolar events, possible identification of very -high energy neutrinos and multi-muon events. February 11, 2011 Mini NANO Workshop 23
